+- [Unaligned references to packed fields are now a hard error.](https://github.com/rust-lang/rust/pull/102513/) This has been a warning since 1.53, and denied by default with a future-compatibility warning since 1.62.

+- [Cargo now emits errors on invalid characters in a registry token.](https://github.com/rust-lang/cargo/pull/11600/)
+- [When `default-features` is set to false of a workspace dependency, and an inherited dependency of a member has `default-features = true`, Cargo will enable default features of that dependency.](https://github.com/rust-lang/cargo/pull/11409/)
+- [Cargo denies `CARGO_HOME` in the `[env]` configuration table. Cargo itself doesn't pick up this value, but recursive calls to cargo would, which was not intended.](https://github.com/rust-lang/cargo/pull/11644/)
+- [Debuginfo for build dependencies is now off if not explicitly set. This is expected to improve the overall build time.](https://github.com/rust-lang/cargo/pull/11252/)

+- [As previously announced 1.41 will be the last tier 1 release for 32-bit
Apple targets.][apple-32bit-drop] This means that the source code is still
available to build, but the targets are no longer being tested and release
binaries for those platforms will no longer be distributed by the Rust project.

- ./y.rs prepare [--out-dir DIR]
- ./y.rs build [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
- ./y.rs test [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
-
-OPTIONS:
- --sysroot none|clif|llvm
- Which sysroot libraries to use:
- `none` will not include any standard library in the sysroot.
- `clif` will build the standard library using Cranelift.
- `llvm` will use the pre-compiled standard library of rustc which is compiled with LLVM.
-
- --out-dir DIR
- Specify the directory in which the download, build and dist directories are stored.
- By default this is the working directory.
-
- --no-unstable-features
- fSome features are not yet ready for production usage. This option will disable these
- features. This includes the JIT mode and inline assembly support.

+The build system of cg_clif.
+
+USAGE:
+ ./y.rs prepare [--out-dir DIR]
+ ./y.rs build [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
+ ./y.rs test [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
+ ./y.rs abi-cafe [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
+ ./y.rs bench [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
+
+OPTIONS:
+ --debug
+ Build cg_clif and the standard library in debug mode rather than release mode.
+ Warning: An unoptimized cg_clif is very slow.
+
+ --sysroot none|clif|llvm
+ Which sysroot libraries to use:
+ `none` will not include any standard library in the sysroot.
+ `clif` will build the standard library using Cranelift.
+ `llvm` will use the pre-compiled standard library of rustc which is compiled with LLVM.
+
+ --out-dir DIR
+ Specify the directory in which the download, build and dist directories are stored.
+ By default this is the working directory.
+
+ --no-unstable-features
+ Some features are not yet ready for production usage. This option will disable these
+ features. This includes the JIT mode and inline assembly support.
+
+REQUIREMENTS:
+ * Rustup: The build system has a hard coded dependency on rustup to install the right nightly
+ version and make sure it is used where necessary.
+ * Git: `./y.rs prepare` uses git for applying patches and on Windows for downloading test repos.
+ * Curl and tar (non-Windows only): Used by `./y.rs prepare` to download a single commit for
+ repos. Git will be used to clone the whole repo when using Windows.
+ * [Hyperfine](https://github.com/sharkdp/hyperfine/): Used for benchmarking with `./y.rs bench`.

+
+Erroneous code example:
+
+```compile_fail,E0789
+// NOTE: both of these attributes are perma-unstable and should *never* be
+// used outside of the compiler and standard library.
+#![feature(rustc_attrs)]
+#![feature(staged_api)]

+struct Foo;
+// ^^^ error: `rustc_allowed_through_unstable_modules` attribute must be
+// paired with a `stable` attribute
+```
+
+Typically when an item is marked with a `stable` attribute, the modules that
+enclose the item must also be marked with `stable` attributes, otherwise the
+item becomes *de facto* unstable. `#[rustc_allowed_through_unstable_modules]`
+is a workaround which allows an item to "escape" its unstable parent modules.
+This error occurs when an item is marked with
+`#[rustc_allowed_through_unstable_modules]` but no supplementary `stable`
+attribute exists. See [#99288](https://github.com/rust-lang/rust/pull/99288)
+for an example of `#[rustc_allowed_through_unstable_modules]` in use.

+An unaligned references to a field of a [packed] struct got created.
+
+Erroneous code example:
+
+```compile_fail,E0793
+#[repr(packed)]
+pub struct Foo {
+ field1: u64,
+ field2: u8,
+}
+
+unsafe {
+ let foo = Foo { field1: 0, field2: 0 };
+ // Accessing the field directly is fine.
+ let val = foo.field1;
+ // A reference to a packed field causes a error.
+ let val = &foo.field1; // ERROR
+ // An implicit `&` is added in format strings, causing the same error.
+ println!("{}", foo.field1); // ERROR
+}
+```
+
+Creating a reference to an insufficiently aligned packed field is
+[undefined behavior] and therefore disallowed. Using an `unsafe` block does not
+change anything about this. Instead, the code should do a copy of the data in
+the packed field or use raw pointers and unaligned accesses.
+
+```
+#[repr(packed)]
+pub struct Foo {
+ field1: u64,
+ field2: u8,
+}
+
+unsafe {
+ let foo = Foo { field1: 0, field2: 0 };
+
+ // Instead of a reference, we can create a raw pointer...
+ let ptr = std::ptr::addr_of!(foo.field1);
+ // ... and then (crucially!) access it in an explicitly unaligned way.
+ let val = unsafe { ptr.read_unaligned() };
+ // This would *NOT* be correct:
+ // let val = unsafe { *ptr }; // Undefined Behavior due to unaligned load!
+
+ // For formatting, we can create a copy to avoid the direct reference.
+ let copy = foo.field1;
+ println!("{}", copy);
+ // Creating a copy can be written in a single line with curly braces.
+ // (This is equivalent to the two lines above.)
+ println!("{}", { foo.field1 });
+}
+```
+
+### Additional information
+
+Note that this error is specifically about *references* to packed fields.
+Direct by-value access of those fields is fine, since then the compiler has
+enough information to generate the correct kind of access.
+
+See [issue #82523] for more information.

-//! A folding traversal mechanism for complex data structures that contain type
-//! information.
-//!
-//! This is a modifying traversal. It consumes the data structure, producing a
-//! (possibly) modified version of it. Both fallible and infallible versions are
-//! available. The name is potentially confusing, because this traversal is more
-//! like `Iterator::map` than `Iterator::fold`.
-//!
-//! This traversal has limited flexibility. Only a small number of "types of
-//! interest" within the complex data structures can receive custom
-//! modification. These are the ones containing the most important type-related
-//! information, such as `Ty`, `Predicate`, `Region`, and `Const`.
-//!
-//! There are three groups of traits involved in each traversal.
-//! - `TypeFoldable`. This is implemented once for many types, including:
-//! - Types of interest, for which the methods delegate to the folder.
-//! - All other types, including generic containers like `Vec` and `Option`.
-//! It defines a "skeleton" of how they should be folded.
-//! - `TypeSuperFoldable`. This is implemented only for each type of interest,
-//! and defines the folding "skeleton" for these types.
-//! - `TypeFolder`/`FallibleTypeFolder. One of these is implemented for each
-//! folder. This defines how types of interest are folded.
-//!
-//! This means each fold is a mixture of (a) generic folding operations, and (b)
-//! custom fold operations that are specific to the folder.
-//! - The `TypeFoldable` impls handle most of the traversal, and call into
-//! `TypeFolder`/`FallibleTypeFolder` when they encounter a type of interest.
-//! - A `TypeFolder`/`FallibleTypeFolder` may call into another `TypeFoldable`
-//! impl, because some of the types of interest are recursive and can contain
-//! other types of interest.
-//! - A `TypeFolder`/`FallibleTypeFolder` may also call into a `TypeSuperFoldable`
-//! impl, because each folder might provide custom handling only for some types
-//! of interest, or only for some variants of each type of interest, and then
-//! use default traversal for the remaining cases.
-//!
-//! For example, if you have `struct S(Ty, U)` where `S: TypeFoldable` and `U:
-//! TypeFoldable`, and an instance `s = S(ty, u)`, it would be folded like so:
-//! ```text
-//! s.fold_with(folder) calls
-//! - ty.fold_with(folder) calls
-//! - folder.fold_ty(ty) may call
-//! - ty.super_fold_with(folder)
-//! - u.fold_with(folder)
-//! ```

-//! A visiting traversal mechanism for complex data structures that contain type
-//! information.
-//!
-//! This is a read-only traversal of the data structure.
-//!
-//! This traversal has limited flexibility. Only a small number of "types of
-//! interest" within the complex data structures can receive custom
-//! visitation. These are the ones containing the most important type-related
-//! information, such as `Ty`, `Predicate`, `Region`, and `Const`.
-//!
-//! There are three groups of traits involved in each traversal.
-//! - `TypeVisitable`. This is implemented once for many types, including:
-//! - Types of interest, for which the methods delegate to the visitor.
-//! - All other types, including generic containers like `Vec` and `Option`.
-//! It defines a "skeleton" of how they should be visited.
-//! - `TypeSuperVisitable`. This is implemented only for each type of interest,
-//! and defines the visiting "skeleton" for these types.
-//! - `TypeVisitor`. This is implemented for each visitor. This defines how
-//! types of interest are visited.
-//!
-//! This means each visit is a mixture of (a) generic visiting operations, and (b)
-//! custom visit operations that are specific to the visitor.
-//! - The `TypeVisitable` impls handle most of the traversal, and call into
-//! `TypeVisitor` when they encounter a type of interest.
-//! - A `TypeVisitor` may call into another `TypeVisitable` impl, because some of
-//! the types of interest are recursive and can contain other types of interest.
-//! - A `TypeVisitor` may also call into a `TypeSuperVisitable` impl, because each
-//! visitor might provide custom handling only for some types of interest, or
-//! only for some variants of each type of interest, and then use default
-//! traversal for the remaining cases.
-//!
-//! For example, if you have `struct S(Ty, U)` where `S: TypeVisitable` and `U:
-//! TypeVisitable`, and an instance `s = S(ty, u)`, it would be visited like so:
-//! ```text
-//! s.visit_with(visitor) calls
-//! - ty.visit_with(visitor) calls
-//! - visitor.visit_ty(ty) may call
-//! - ty.super_visit_with(visitor)
-//! - u.visit_with(visitor)
-//! ```

+/// During MIR building, Drop and DropAndReplace terminators are inserted in every place where a drop may occur.
+/// However, in this phase, the presence of these terminators does not guarantee that a destructor will run,
+/// as the target of the drop may be uninitialized.
+/// In general, the compiler cannot determine at compile time whether a destructor will run or not.
+///
+/// At a high level, this pass refines Drop and DropAndReplace to only run the destructor if the
+/// target is initialized. The way this is achievied is by inserting drop flags for every variable
+/// that may be dropped, and then using those flags to determine whether a destructor should run.
+/// This pass also removes DropAndReplace, replacing it with a Drop paired with an assign statement.
+/// Once this is complete, Drop terminators in the MIR correspond to a call to the "drop glue" or
+/// "drop shim" for the type of the dropped place.
+///
+/// This pass relies on dropped places having an associated move path, which is then used to determine
+/// the initialization status of the place and its descendants.
+/// It's worth noting that a MIR containing a Drop without an associated move path is probably ill formed,
+/// as it would allow running a destructor on a place behind a reference:
+///
+/// ```text

-//! Write the output of rustc's analysis to an implementor of Dump.
-//!
-//! Dumping the analysis is implemented by walking the AST and getting a bunch of
-//! info out from all over the place. We use `DefId`s to identify objects. The
-//! tricky part is getting syntactic (span, source text) and semantic (reference
-//! `DefId`s) information for parts of expressions which the compiler has discarded.
-//! E.g., in a path `foo::bar::baz`, the compiler only keeps a span for the whole
-//! path and a reference to `baz`, but we want spans and references for all three
-//! idents.
-//!
-//! SpanUtils is used to manipulate spans. In particular, to extract sub-spans
-//! from spans (e.g., the span for `bar` from the above example path).
-//! DumpVisitor walks the AST and processes it, and Dumper is used for
-//! recording the output.

-// A signature is a string representation of an item's type signature, excluding
-// any body. It also includes ids for any defs or refs in the signature. For
-// example:
-//
-// ```
-// fn foo(x: String) {
-// println!("{}", x);
-// }
-// ```
-// The signature string is something like "fn foo(x: String) {}" and the signature
-// will have defs for `foo` and `x` and a ref for `String`.
-//
-// All signature text should parse in the correct context (i.e., in a module or
-// impl, etc.). Clients may want to trim trailing `{}` or `;`. The text of a
-// signature is not guaranteed to be stable (it may improve or change as the
-// syntax changes, or whitespace or punctuation may change). It is also likely
-// not to be pretty - no attempt is made to prettify the text. It is recommended
-// that clients run the text through Rustfmt.
-//
-// This module generates Signatures for items by walking the AST and looking up
-// references.
-//
-// Signatures do not include visibility info. I'm not sure if this is a feature
-// or an omission (FIXME).
-//
-// FIXME where clauses need implementing, defs/refs in generics are mostly missing.

+//! A folding traversal mechanism for complex data structures that contain type
+//! information.
+//!
+//! This is a modifying traversal. It consumes the data structure, producing a
+//! (possibly) modified version of it. Both fallible and infallible versions are
+//! available. The name is potentially confusing, because this traversal is more
+//! like `Iterator::map` than `Iterator::fold`.
+//!
+//! This traversal has limited flexibility. Only a small number of "types of
+//! interest" within the complex data structures can receive custom
+//! modification. These are the ones containing the most important type-related
+//! information, such as `Ty`, `Predicate`, `Region`, and `Const`.
+//!
+//! There are three groups of traits involved in each traversal.
+//! - `TypeFoldable`. This is implemented once for many types, including:
+//! - Types of interest, for which the methods delegate to the folder.
+//! - All other types, including generic containers like `Vec` and `Option`.
+//! It defines a "skeleton" of how they should be folded.
+//! - `TypeSuperFoldable`. This is implemented only for each type of interest,
+//! and defines the folding "skeleton" for these types.
+//! - `TypeFolder`/`FallibleTypeFolder. One of these is implemented for each
+//! folder. This defines how types of interest are folded.
+//!
+//! This means each fold is a mixture of (a) generic folding operations, and (b)
+//! custom fold operations that are specific to the folder.
+//! - The `TypeFoldable` impls handle most of the traversal, and call into
+//! `TypeFolder`/`FallibleTypeFolder` when they encounter a type of interest.
+//! - A `TypeFolder`/`FallibleTypeFolder` may call into another `TypeFoldable`
+//! impl, because some of the types of interest are recursive and can contain
+//! other types of interest.
+//! - A `TypeFolder`/`FallibleTypeFolder` may also call into a `TypeSuperFoldable`
+//! impl, because each folder might provide custom handling only for some types
+//! of interest, or only for some variants of each type of interest, and then
+//! use default traversal for the remaining cases.
+//!
+//! For example, if you have `struct S(Ty, U)` where `S: TypeFoldable` and `U:
+//! TypeFoldable`, and an instance `s = S(ty, u)`, it would be folded like so:
+//! ```text
+//! s.fold_with(folder) calls
+//! - ty.fold_with(folder) calls
+//! - folder.fold_ty(ty) may call
+//! - ty.super_fold_with(folder)
+//! - u.fold_with(folder)
+//! ```

+//! A visiting traversal mechanism for complex data structures that contain type
+//! information.
+//!
+//! This is a read-only traversal of the data structure.
+//!
+//! This traversal has limited flexibility. Only a small number of "types of
+//! interest" within the complex data structures can receive custom
+//! visitation. These are the ones containing the most important type-related
+//! information, such as `Ty`, `Predicate`, `Region`, and `Const`.
+//!
+//! There are three groups of traits involved in each traversal.
+//! - `TypeVisitable`. This is implemented once for many types, including:
+//! - Types of interest, for which the methods delegate to the visitor.
+//! - All other types, including generic containers like `Vec` and `Option`.
+//! It defines a "skeleton" of how they should be visited.
+//! - `TypeSuperVisitable`. This is implemented only for each type of interest,
+//! and defines the visiting "skeleton" for these types.
+//! - `TypeVisitor`. This is implemented for each visitor. This defines how
+//! types of interest are visited.
+//!
+//! This means each visit is a mixture of (a) generic visiting operations, and (b)
+//! custom visit operations that are specific to the visitor.
+//! - The `TypeVisitable` impls handle most of the traversal, and call into
+//! `TypeVisitor` when they encounter a type of interest.
+//! - A `TypeVisitor` may call into another `TypeVisitable` impl, because some of
+//! the types of interest are recursive and can contain other types of interest.
+//! - A `TypeVisitor` may also call into a `TypeSuperVisitable` impl, because each
+//! visitor might provide custom handling only for some types of interest, or
+//! only for some variants of each type of interest, and then use default
+//! traversal for the remaining cases.
+//!
+//! For example, if you have `struct S(Ty, U)` where `S: TypeVisitable` and `U:
+//! TypeVisitable`, and an instance `s = S(ty, u)`, it would be visited like so:
+//! ```text
+//! s.visit_with(visitor) calls
+//! - ty.visit_with(visitor) calls
+//! - visitor.visit_ty(ty) may call
+//! - ty.super_visit_with(visitor)
+//! - u.visit_with(visitor)
+//! ```

+/// IPv4-compatible IPv6 addresses are defined in [IETF RFC 4291 Section 2.5.5.1], and have been officially deprecated.
+/// The RFC describes the format of an "IPv4-Compatible IPv6 address" as follows:
+///
+/// ```text
+/// | 80 bits | 16 | 32 bits |
+/// +--------------------------------------+--------------------------+
+/// |0000..............................0000|0000| IPv4 address |
+/// +--------------------------------------+----+---------------------+
+/// ```
+/// So `::a.b.c.d` would be an IPv4-compatible IPv6 address representing the IPv4 address `a.b.c.d`.
+///
+/// To convert from an IPv4 address to an IPv4-compatible IPv6 address, use [`Ipv4Addr::to_ipv6_compatible`].
+/// Use [`Ipv6Addr::to_ipv4`] to convert an IPv4-compatible IPv6 address to the canonical IPv4 address.
+///
+/// [IETF RFC 4291 Section 2.5.5.1]: https://datatracker.ietf.org/doc/html/rfc4291#section-2.5.5.1
+///
+/// ### IPv4-Mapped IPv6 Addresses
+///
+/// IPv4-mapped IPv6 addresses are defined in [IETF RFC 4291 Section 2.5.5.2].
+/// The RFC describes the format of an "IPv4-Mapped IPv6 address" as follows:
+///
+/// ```text
+/// | 80 bits | 16 | 32 bits |
+/// +--------------------------------------+--------------------------+
+/// |0000..............................0000|FFFF| IPv4 address |
+/// +--------------------------------------+----+---------------------+
+/// ```
+/// So `::ffff:a.b.c.d` would be an IPv4-mapped IPv6 address representing the IPv4 address `a.b.c.d`.
+///
+/// To convert from an IPv4 address to an IPv4-mapped IPv6 address, use [`Ipv4Addr::to_ipv6_mapped`].
+/// Use [`Ipv6Addr::to_ipv4`] to convert an IPv4-mapped IPv6 address to the canonical IPv4 address.
+/// Note that this will also convert the IPv6 loopback address `::1` to `0.0.0.1`. Use
+/// [`Ipv6Addr::to_ipv4_mapped`] to avoid this.
+///
+/// [IETF RFC 4291 Section 2.5.5.2]: https://datatracker.ietf.org/doc/html/rfc4291#section-2.5.5.2
+///
+/// # Textual representation
+///
+/// `Ipv6Addr` provides a [`FromStr`] implementation. There are many ways to represent
+/// an IPv6 address in text, but in general, each segments is written in hexadecimal
+/// notation, and segments are separated by `:`. For more information, see
+/// [IETF RFC 5952].
+///
+/// [`FromStr`]: crate::str::FromStr
+/// [IETF RFC 5952]: https://tools.ietf.org/html/rfc5952
+///
+/// # Examples
+///
+/// ```
+/// use std::net::Ipv6Addr;
+///
+/// let localhost = Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1);
+/// assert_eq!("::1".parse(), Ok(localhost));
+/// assert_eq!(localhost.is_loopback(), true);
+/// ```

-/// # Embedding IPv4 Addresses
-///
-/// See [`IpAddr`] for a type encompassing both IPv4 and IPv6 addresses.
-///
-/// To assist in the transition from IPv4 to IPv6 two types of IPv6 addresses that embed an IPv4 address were defined:
-/// IPv4-compatible and IPv4-mapped addresses. Of these IPv4-compatible addresses have been officially deprecated.
-///
-/// Both types of addresses are not assigned any special meaning by this implementation,
-/// other than what the relevant standards prescribe. This means that an address like `::ffff:127.0.0.1`,
-/// while representing an IPv4 loopback address, is not itself an IPv6 loopback address; only `::1` is.
-/// To handle these so called "IPv4-in-IPv6" addresses, they have to first be converted to their canonical IPv4 address.
-///
-/// ### IPv4-Compatible IPv6 Addresses
-///
-/// IPv4-compatible IPv6 addresses are defined in [IETF RFC 4291 Section 2.5.5.1], and have been officially deprecated.
-/// The RFC describes the format of an "IPv4-Compatible IPv6 address" as follows:

-/// ```text
-/// | 80 bits | 16 | 32 bits |
-/// +--------------------------------------+--------------------------+
-/// |0000..............................0000|0000| IPv4 address |
-/// +--------------------------------------+----+---------------------+
-/// ```
-/// So `::a.b.c.d` would be an IPv4-compatible IPv6 address representing the IPv4 address `a.b.c.d`.
-///
-/// To convert from an IPv4 address to an IPv4-compatible IPv6 address, use [`Ipv4Addr::to_ipv6_compatible`].
-/// Use [`Ipv6Addr::to_ipv4`] to convert an IPv4-compatible IPv6 address to the canonical IPv4 address.
-///
-/// [IETF RFC 4291 Section 2.5.5.1]: https://datatracker.ietf.org/doc/html/rfc4291#section-2.5.5.1
-///
-/// ### IPv4-Mapped IPv6 Addresses
-///
-/// IPv4-mapped IPv6 addresses are defined in [IETF RFC 4291 Section 2.5.5.2].
-/// The RFC describes the format of an "IPv4-Mapped IPv6 address" as follows:
-///
-/// ```text
-/// | 80 bits | 16 | 32 bits |
-/// +--------------------------------------+--------------------------+
-/// |0000..............................0000|FFFF| IPv4 address |
-/// +--------------------------------------+----+---------------------+
-/// ```
-/// So `::ffff:a.b.c.d` would be an IPv4-mapped IPv6 address representing the IPv4 address `a.b.c.d`.
-///
-/// To convert from an IPv4 address to an IPv4-mapped IPv6 address, use [`Ipv4Addr::to_ipv6_mapped`].
-/// Use [`Ipv6Addr::to_ipv4`] to convert an IPv4-mapped IPv6 address to the canonical IPv4 address.
-/// Note that this will also convert the IPv6 loopback address `::1` to `0.0.0.1`. Use
-/// [`Ipv6Addr::to_ipv4_mapped`] to avoid this.
-///
-/// [IETF RFC 4291 Section 2.5.5.2]: https://datatracker.ietf.org/doc/html/rfc4291#section-2.5.5.2
-///
-/// # Textual representation
-///
-/// `Ipv6Addr` provides a [`FromStr`] implementation. There are many ways to represent
-/// an IPv6 address in text, but in general, each segments is written in hexadecimal
-/// notation, and segments are separated by `:`. For more information, see
-/// [IETF RFC 5952].

-//! A wait-flag-based thread parker.
-//!
-//! Some operating systems provide low-level parking primitives like wait counts,
-//! event flags or semaphores which are not susceptible to race conditions (meaning
-//! the wakeup can occur before the wait operation). To implement the `std` thread
-//! parker on top of these primitives, we only have to ensure that parking is fast
-//! when the thread token is available, the atomic ordering guarantees are maintained
-//! and spurious wakeups are minimized.
-//!
-//! To achieve this, this parker uses an atomic variable with three states: `EMPTY`,
-//! `PARKED` and `NOTIFIED`:
-//! * `EMPTY` means the token has not been made available, but the thread is not
-//! currently waiting on it.
-//! * `PARKED` means the token is not available and the thread is parked.
-//! * `NOTIFIED` means the token is available.
-//!
-//! `park` and `park_timeout` change the state from `EMPTY` to `PARKED` and from
-//! `NOTIFIED` to `EMPTY`. If the state was `NOTIFIED`, the thread was unparked and
-//! execution can continue without calling into the OS. If the state was `EMPTY`,
-//! the token is not available and the thread waits on the primitive (here called
-//! "wait flag").
-//!
-//! `unpark` changes the state to `NOTIFIED`. If the state was `PARKED`, the thread
-//! is or will be sleeping on the wait flag, so we raise it.

is bootstrapped and in general, some of the technical details of the build
system.
-## Using rustbuild
+Note that this README only covers internal information, not how to use the tool.
+Please check [bootstrapping dev guide][bootstrapping-dev-guide] for further information.
-The rustbuild build system has a primary entry point, a top level `x.py` script:
+[bootstrapping-dev-guide]: https://rustc-dev-guide.rust-lang.org/building/bootstrapping.html
-```sh
-$ python ./x.py build
-```
-
-Note that if you're on Unix, you should be able to execute the script directly:
-
-```sh
-$ ./x.py build
-```
-
-The script accepts commands, flags, and arguments to determine what to do:
-
-* `build` - a general purpose command for compiling code. Alone, `build` will
- bootstrap the entire compiler, and otherwise, arguments passed indicate what to
- build. For example:
-
- ```
- # build the whole compiler
- ./x.py build --stage 2
-
- # build the stage1 compiler
- ./x.py build
-
- # build stage0 libstd
- ./x.py build --stage 0 library/std
-
- # build a particular crate in stage0
- ./x.py build --stage 0 library/test
- ```
-
- If files that would normally be rebuilt from stage 0 are dirty, the rebuild can be
- overridden using `--keep-stage 0`. Using `--keep-stage n` will skip all steps
- that belong to stage n or earlier:
-
- ```
- # build stage 1, keeping old build products for stage 0
- ./x.py build --keep-stage 0
- ```
-
-* `test` - a command for executing unit tests. Like the `build` command, this
- will execute the entire test suite by default, and otherwise, it can be used to
- select which test suite is run:
-
- ```
- # run all unit tests
- ./x.py test
-
- # execute tool tests
- ./x.py test tidy
-
- # execute the UI test suite
- ./x.py test tests/ui
-
- # execute only some tests in the UI test suite
- ./x.py test tests/ui --test-args substring-of-test-name
-
- # execute tests in the standard library in stage0
- ./x.py test --stage 0 library/std
-
- # execute tests in the core and standard library in stage0,
- # without running doc tests (thus avoid depending on building the compiler)
- ./x.py test --stage 0 --no-doc library/core library/std
+## Introduction
- # execute all doc tests
- ./x.py test src/doc
- ```
+The build system defers most of the complicated logic managing invocations
+of rustc and rustdoc to Cargo itself. However, moving through various stages
+and copying artifacts is still necessary for it to do. Each time rustbuild
+is invoked, it will iterate through the list of predefined steps and execute
+each serially in turn if it matches the paths passed or is a default rule.
+For each step rustbuild relies on the step internally being incremental and
+parallel. Note, though, that the `-j` parameter to rustbuild gets forwarded
+to appropriate test harnesses and such.
-* `doc` - a command for building documentation. Like above, can take arguments
- for what to document.
-
-## Configuring rustbuild
-
-rustbuild offers a TOML-based configuration system with a `config.toml`
-file. An example of this configuration can be found at `config.toml.example`,
-and the configuration file can also be passed as `--config path/to/config.toml`
-if the build system is being invoked manually (via the python script).
-
-You can generate a config.toml using `./configure` options if you want to automate creating the file without having to edit it.
-
-Finally, rustbuild makes use of the [cc-rs crate] which has [its own
-method][env-vars] of configuring C compilers and C flags via environment
-variables.

-## Build stages
+## Build phases
The rustbuild build system goes through a few phases to actually build the
compiler. What actually happens when you invoke rustbuild is:
-1. The entry point script, `x.py` is run. This script is
- responsible for downloading the stage0 compiler/Cargo binaries, and it then
- compiles the build system itself (this folder). Finally, it then invokes the
- actual `bootstrap` binary build system.

+ Finally, it then invokes the actual `bootstrap` binary build system.
2. In Rust, `bootstrap` will slurp up all configuration, perform a number of
sanity checks (whether compilers exist, for example), and then start building the
stage0 artifacts.

The goal of each stage is to (a) leverage Cargo as much as possible and failing
that (b) leverage Rust as much as possible!
-## Incremental builds
-
-You can configure rustbuild to use incremental compilation with the
-`--incremental` flag:
-
-```sh
-$ ./x.py build --incremental
-```
-
-The `--incremental` flag will store incremental compilation artifacts
-in `build/<host>/stage0-incremental`. Note that we only use incremental
-compilation for the stage0 -> stage1 compilation -- this is because
-the stage1 compiler is changing, and we don't try to cache and reuse
-incremental artifacts across different versions of the compiler.
-
-You can always drop the `--incremental` to build as normal (but you
-will still be using the local nightly as your bootstrap).

-## Cargo projects
-
-The current build is unfortunately not quite as simple as `cargo build` in a
-directory, but rather the compiler is split into three different Cargo projects:
-
-* `library/std` - the standard library
-* `library/test` - testing support, depends on libstd
-* `compiler/rustc` - the actual compiler itself
-
-Each "project" has a corresponding Cargo.lock file with all dependencies, and
-this means that building the compiler involves running Cargo three times. The
-structure here serves two goals:
-
-1. Facilitating dependencies coming from crates.io. These dependencies don't
- depend on `std`, so libstd is a separate project compiled ahead of time
- before the actual compiler builds.
-2. Splitting "host artifacts" from "target artifacts". That is, when building
- code for an arbitrary target, you don't need the entire compiler, but you'll
- end up needing libraries like libtest that depend on std but also want to use
- crates.io dependencies. Hence, libtest is split out as its own project that
- is sequenced after `std` but before `rustc`. This project is built for all
- targets.
-
-There is some loss in build parallelism here because libtest can be compiled in
-parallel with a number of rustc artifacts, but in theory, the loss isn't too bad!
-
-## Build tools
-
-We've actually got quite a few tools that we use in the compiler's build system
-and for testing. To organize these, each tool is a project in `src/tools` with a
-corresponding `Cargo.toml`. All tools are compiled with Cargo (currently having
-independent `Cargo.lock` files) and do not currently explicitly depend on the
-compiler or standard library. Compiling each tool is sequenced after the
-appropriate libstd/libtest/librustc compile above.
-
## Extending rustbuild
-So, you'd like to add a feature to the rustbuild build system or just fix a bug.
-Great! One of the major motivational factors for moving away from `make` is that
-Rust is in theory much easier to read, modify, and write. If you find anything
-excessively confusing, please open an issue on this, and we'll try to get it
-documented or simplified, pronto.
+When you use the bootstrap system, you'll call it through the entry point script
+(`x`, `x.ps1`, or `x.py`). However, most of the code lives in `src/bootstrap`.
+`bootstrap` has a difficult problem: it is written in Rust, but yet it is run
+before the Rust compiler is built! To work around this, there are two components
+of bootstrap: the main one written in rust, and `bootstrap.py`. `bootstrap.py`
+is what gets run by entry point script. It takes care of downloading the `stage0`
+compiler, which will then build the bootstrap binary written in Rust.
-First up, you'll probably want to read over the documentation above, as that'll
-give you a high level overview of what rustbuild is doing. You also probably
-want to play around a bit yourself by just getting it up and running before you
-dive too much into the actual build system itself.
+Because there are two separate codebases behind `x.py`, they need to
+be kept in sync. In particular, both `bootstrap.py` and the bootstrap binary
+parse `config.toml` and read the same command line arguments. `bootstrap.py`
+keeps these in sync by setting various environment variables, and the
+programs sometimes have to add arguments that are explicitly ignored, to be
+read by the other.
-After that, each module in rustbuild should have enough documentation to keep
-you up and running. Some general areas that you may be interested in modifying

//! crates.io and Cargo.
//! * A standard interface to build across all platforms, including MSVC
//!
-//! ## Architecture
-//!
-//! The build system defers most of the complicated logic managing invocations
-//! of rustc and rustdoc to Cargo itself. However, moving through various stages
-//! and copying artifacts is still necessary for it to do. Each time rustbuild
-//! is invoked, it will iterate through the list of predefined steps and execute
-//! each serially in turn if it matches the paths passed or is a default rule.
-//! For each step rustbuild relies on the step internally being incremental and
-//! parallel. Note, though, that the `-j` parameter to rustbuild gets forwarded
-//! to appropriate test harnesses and such.
-//!
-//! Most of the "meaty" steps that matter are backed by Cargo, which does indeed
-//! have its own parallelism and incremental management. Later steps, like
-//! tests, aren't incremental and simply run the entire suite currently.
-//! However, compiletest itself tries to avoid running tests when the artifacts
-//! that are involved (mainly the compiler) haven't changed.
-//!
-//! When you execute `x.py build`, the steps executed are:
-//!
-//! * First, the python script is run. This will automatically download the
-//! stage0 rustc and cargo according to `src/stage0.json`, or use the cached
-//! versions if they're available. These are then used to compile rustbuild
-//! itself (using Cargo). Finally, control is then transferred to rustbuild.
-//!
-//! * Rustbuild takes over, performs sanity checks, probes the environment,
-//! reads configuration, and starts executing steps as it reads the command
-//! line arguments (paths) or going through the default rules.
-//!
-//! The build output will be something like the following:
-//!
-//! Building stage0 std artifacts
-//! Copying stage0 std
-//! Building stage0 test artifacts
-//! Copying stage0 test
-//! Building stage0 compiler artifacts
-//! Copying stage0 rustc
-//! Assembling stage1 compiler
-//! Building stage1 std artifacts
-//! Copying stage1 std
-//! Building stage1 test artifacts
-//! Copying stage1 test
-//! Building stage1 compiler artifacts
-//! Copying stage1 rustc
-//! Assembling stage2 compiler
-//! Uplifting stage1 std
-//! Uplifting stage1 test
-//! Uplifting stage1 rustc
-//!
-//! Let's disect that a little:
-//!
-//! ## Building stage0 {std,test,compiler} artifacts
-//!
-//! These steps use the provided (downloaded, usually) compiler to compile the
-//! local Rust source into libraries we can use.
-//!
-//! ## Copying stage0 {std,test,rustc}
-//!
-//! This copies the build output from Cargo into
-//! `build/$HOST/stage0-sysroot/lib/rustlib/$ARCH/lib`. FIXME: this step's
-//! documentation should be expanded -- the information already here may be
-//! incorrect.
-//!
-//! ## Assembling stage1 compiler
-//!
-//! This copies the libraries we built in "building stage0 ... artifacts" into
-//! the stage1 compiler's lib directory. These are the host libraries that the
-//! compiler itself uses to run. These aren't actually used by artifacts the new
-//! compiler generates. This step also copies the rustc and rustdoc binaries we
-//! generated into build/$HOST/stage/bin.
-//!
-//! The stage1/bin/rustc is a fully functional compiler, but it doesn't yet have
-//! any libraries to link built binaries or libraries to. The next 3 steps will
-//! provide those libraries for it; they are mostly equivalent to constructing
-//! the stage1/bin compiler so we don't go through them individually.
-//!
-//! ## Uplifting stage1 {std,test,rustc}
-//!
-//! This step copies the libraries from the stage1 compiler sysroot into the
-//! stage2 compiler. This is done to avoid rebuilding the compiler; libraries
-//! we'd build in this step should be identical (in function, if not necessarily
-//! identical on disk) so there's no need to recompile the compiler again. Note
-//! that if you want to, you can enable the full-bootstrap option to change this
-//! behavior.
-//!
-//! Each step is driven by a separate Cargo project and rustbuild orchestrates
-//! copying files between steps and otherwise preparing for Cargo to run.
-//!
//! ## Further information
//!
//! More documentation can be found in each respective module below, and you can

A board crate is the perfect starting point, if you're new to embedded Rust. They nicely abstract the HW details that might be overwhelming when starting studying this subject, and makes standard tasks easy, like turning a LED on or off. The functionality it exposes varies a lot between boards. Since this book aims at staying hardware agnostic, the board crates won't be covered by this book.

# AST Validation
-AST validation is the process of checking various correctness properties about
-the AST after macro expansion.
+<!-- toc -->
-**TODO**: write this chapter. [#656](https://github.com/rust-lang/rustc-dev-guide/issues/656)
+## About
+
+_AST validation_ is a separate AST pass that visits each
+item in the tree and performs simple checks. This pass
+doesn't perform any complex analysis, type checking or
+name resolution.
+
+Before performing any validation, the compiler first expands
+the macros. Then this pass performs validations to check
+that each AST item is in the correct state. And when this pass
+is done, the compiler runs the crate resolution pass.
+
+## Validations
+
+Validations are defined in `AstValidator` type, which
+itself is located in `rustc_ast_passes` crate. This
+type implements various simple checks which emit errors
+when certain language rules are broken.
+
+In addition, `AstValidator` implements `Visitor` trait
+that defines how to visit AST items (which can be functions,
+traits, enums, etc).
+
+For each item, visitor performs specific checks. For
+example, when visiting a function declaration,
+`AstValidator` checks that the function has:
+
+* no more than `u16::MAX` parameters;
+* c-variadic functions are declared with at least one named argument;
+* c-variadic argument goes the last in the declaration;
+* documentation comments aren't applied to function parameters;
+* and other validations.

+In this part, we will investigate the build command's stdout in an action

+
+### Building stage0 {std,compiler} artifacts
+
+These steps use the provided (downloaded, usually) compiler to compile the
+local Rust source into libraries we can use.
+
+### Copying stage0 {std,rustc}
+
+This copies the library and compiler artifacts from Cargo into
+`stage0-sysroot/lib/rustlib/{target-triple}/lib`
+
+### Assembling stage1 compiler
+
+This copies the libraries we built in "building stage0 ... artifacts" into
+the stage1 compiler's lib directory. These are the host libraries that the
+compiler itself uses to run. These aren't actually used by artifacts the new
+compiler generates. This step also copies the rustc and rustdoc binaries we
+generated into `build/$HOST/stage/bin`.
+
+The stage1/bin/rustc is a fully functional compiler, but it doesn't yet have
+any libraries to link built binaries or libraries to. The next 3 steps will
+provide those libraries for it; they are mostly equivalent to constructing
+the stage1/bin compiler so we don't go through them individually.

+### Neovim
+
+For Neovim users there are several options for configuring for rustc. The easiest way is by using
+[neoconf.nvim](https://github.com/folke/neoconf.nvim/), which allows for project-local
+configuration files with the native LSP. The steps for how to use it are below. Note that requires
+Rust-Analyzer to already be configured with Neovim. Steps for this can be
+[found here](https://rust-analyzer.github.io/manual.html#nvim-lsp).
+
+1. First install the plugin. This can be done by following the steps in the README.
+2. Run `x.py setup`, which will have a prompt for it to create a `.vscode/settings.json` file.
+`neoconf` is able to read and update Rust-Analyzer settings automatically when the project is
+opened when this file is detected.
+
+If you're running `coc.nvim`, you can use `:CocLocalConfig` to create a
+`.vim/coc-settings.json` and copy the settings from
+[this file](https://github.com/rust-lang/rust/blob/master/src/etc/vscode_settings.json).
+
+Another way is without a plugin, and creating your own logic in your configuration. To do this you
+must translate the JSON to Lua yourself. The translation is 1:1 and fairly straight-forward. It
+must be put in the `["rust-analyzer"]` key of the setup table, which is
+[shown here](https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md#rust_analyzer)
+
+If you would like to use the build task that is described above, you may either make your own
+command in your config, or you can install a plugin such as
+[overseer.nvim](https://github.com/stevearc/overseer.nvim) that can [read VSCode's `task.json`
+files](https://github.com/stevearc/overseer.nvim/blob/master/doc/guides.md#vs-code-tasks), and

+# Canonicalization
+
+Canonicalization is the process of *isolating* a value from its context and is necessary
+for global caching of goals which include inference variables.
+
+The idea is that given the goals `u32: Trait<?x>` and `u32: Trait<?y>`, where `?x` and `?y`
+are two different currently unconstrained inference variables, we should get the same result
+for both goals. We can therefore prove *the canonical query* `exists<T> u32: Trait<T>` once
+and reuse the result.
+
+Let's first go over the way canonical queries work and then dive into the specifics of
+how canonicalization works.
+
+## A walkthrough of canonical queries
+
+To make this a bit easier, let's use the trait goal `u32: Trait<?x>` as an example with the
+assumption that the only relevant impl is `impl<T> Trait<Vec<T>> for u32`.
+
+### Canonicalizing the input
+
+We start by *canonicalizing* the goal, replacing inference variables with existential and
+placeholders with universal bound variables. This would result in the *canonical goal*
+`exists<T> u32: Trait<T>`.
+
+We remember the original values of all bound variables in the original context. Here this would
+map `T` back to `?x`. These original values are used later on when dealing with the query
+response.
+
+We now call the canonical query with the canonical goal.
+
+### Instantiating the canonical goal inside of the query
+
+To actually try to prove the canonical goal we start by instantiating the bound variables with
+inference variables and placeholders again.
+
+This happens inside of the query in a completely separate `InferCtxt`. Inside of the query we
+now have a goal `u32: Trait<?0>`. We also remember which value we've used to instantiate the bound
+variables in the canonical goal, which maps `T` to `?0`.
+
+We now compute the goal `u32: Trait<?0>` and figure out that this holds, but we've constrained
+`?0` to `Vec<?1>`. We finally convert this result to something useful to the caller.
+
+### Canonicalizing the query response
+
+We have to return to the caller both whether the goal holds, and the inference constraints
+from inside of the query.
+
+To return the inference results to the caller we canonicalize the mapping from bound variables
+to the instantiated values in the query. This means that the query response is `Certainty::Yes`
+and a mapping from `T` to `exists<U> Vec<U>`.
+
+### Instantiating the query response
+
+The caller now has to apply the constraints returned by the query. For this they first
+instantiate the bound variables of the canonical response with inference variables and
+placeholders again, so the mapping in the response is now from `T` to `Vec<?z>`.
+
+It now equates the original value of `T` (`?x`) with the value for `T` in the
+response (`Vec<?z>`), which correctly constrains `?x` to `Vec<?z>`.
+
+## `ExternalConstraints`
+
+Computing a trait goal may not only constrain inference variables, it can also add region
+obligations, e.g. given a goal `(): AOutlivesB<'a, 'b>` we would like to return the fact that
+`'a: 'b` has to hold.
+
+This is done by not only returning the mapping from bound variables to the instantiated values
+from the query but also extracting additional `ExternalConstraints` from the `InferCtxt` context
+while building the response.
+
+## How exactly does canonicalization work
+
+TODO: link to code once the PR lands and elaborate
+
+- types and consts: infer to existentially bound var, placeholder to universally bound var,
+ considering universes
+- generic parameters in the input get treated as placeholders in the root universe
+- all regions in the input get all mapped to existentially bound vars and we "uniquify" them.
+ `&'a (): Trait<'a>` gets canonicalized to `exists<'0, '1> &'0 (): Trait<'1>`. We do not care
+ about their universes and simply put all regions into the highest universe of the input.
+- once we collected all canonical vars we compress their universes, see comment in `finalize`.
+- in the output everything in a universe of the caller gets put into the root universe and only
+ gets its correct universe when we unify the var values with the orig values of the caller
+- we do not uniquify regions in the response and don't canonicalize `'static` \ No newline at end of file

+# Coinduction
+
+The trait solver may use coinduction when proving goals.
+Coinduction is fairly subtle so we're giving it its own chapter.
+
+## Coinduction and induction
+
+With induction, we recursively apply proofs until we end up with a finite proof tree.
+Consider the example of `Vec<Vec<Vec<u32>>>: Debug` which results in the following tree.
+
+- `Vec<Vec<Vec<u32>>>: Debug`
+ - `Vec<Vec<u32>>: Debug`
+ - `Vec<u32>: Debug`
+ - `u32: Debug`
+
+This tree is finite. But not all goals we would want to hold have finite proof trees,
+consider the following example:
+
+```rust
+struct List<T> {
+ value: T,
+ next: Option<Box<List<T>>>,
+}
+```
+
+For `List<T>: Send` to hold all its fields have to recursively implement `Send` as well.
+This would result in the following proof tree:
+
+- `List<T>: Send`
+ - `T: Send`
+ - `Option<Box<List<T>>>: Send`
+ - `Box<List<T>>: Send`
+ - `List<T>: Send`
+ - `T: Send`
+ - `Option<Box<List<T>>>: Send`
+ - `Box<List<T>>: Send`
+ - ...
+
+This tree would be infinitely large which is exactly what coinduction is about.
+
+> To **inductively** prove a goal you need to provide a finite proof tree for it.
+> To **coinductively** prove a goal the provided proof tree may be infinite.
+
+## Why is coinduction correct
+
+When checking whether some trait goals holds, we're asking "does there exist an `impl`
+which satisfies this bound". Even if are infinite chains of nested goals, we still have a
+unique `impl` which should be used.
+
+## How to implement coinduction
+
+While our implementation can not check for coinduction by trying to construct an infinite
+tree as that would take infinite resources, it still makes sense to think of coinduction
+from this perspective.
+
+As we cannot check for infinite trees, we instead search for patterns for which we know that
+they would result in an infinite proof tree. The currently pattern we detect are (canonical)
+cycles. If `T: Send` relies on `T: Send` then it's pretty clear that this will just go on forever.
+
+With cycles we have to be careful with caching. Because of canonicalization of regions and
+inference variables encountering a cycle doesn't mean that we would get an infinite proof tree.
+Looking at the following example:
+```rust
+trait Foo {}
+struct Wrapper<T>(T);
+
+impl<T> Foo for Wrapper<Wrapper<T>>
+where
+ Wrapper<T>: Foo
+{}
+```
+Proving `Wrapper<?0>: Foo` uses the impl `impl<T> Foo for Wrapper<Wrapper<T>>` which constrains
+`?0` to `Wrapper<?1>` and then requires `Wrapper<?1>: Foo`. Due to canonicalization this would be
+detected as a cycle.
+
+The idea to solve is to return a *provisional result* whenever we detect a cycle and repeatedly
+retry goals until the *provisional result* is equal to the final result of that goal. We
+start out by using `Yes` with no constraints as the result and then update it to the result of
+the previous iteration whenever we have to rerun.
+
+TODO: elaborate here. We use the same approach as chalk for coinductive cycles.
+Note that the treatment for inductive cycles currently differs by simply returning `Overflow`.
+See [the relevant chapters][chalk] in the chalk book.
+
+[chalk]: https://rust-lang.github.io/chalk/book/recursive/inductive_cycles.html
+
+
+## Future work
+
+We currently only consider auto-traits, `Sized`, and `WF`-goals to be coinductive.
+In the future we pretty much intend for all goals to be coinductive.
+Lets first elaborate on why allowing more coinductive proofs is even desirable.
+
+### Recursive data types already rely on coinduction...
+
+...they just tend to avoid them in the trait solver.
+
+```rust
+enum List<T> {
+ Nil,
+ Succ(T, Box<List<T>>),
+}
+
+impl<T: Clone> Clone for List<T> {
+ fn clone(&self) -> Self {
+ match self {
+ List::Nil => List::Nil,
+ List::Succ(head, tail) => List::Succ(head.clone(), tail.clone()),
+ }
+ }
+}
+```
+
+We are using `tail.clone()` in this impl. For this we have to prove `Box<List<T>>: Clone`
+which requires `List<T>: Clone` but that relies on the impl which we are currently checking.
+By adding that requirement to the `where`-clauses of the impl, which is what we would
+do with [perfect derive], we move that cycle into the trait solver and [get an error][ex1].
+
+### Recursive data types
+
+We also need coinduction to reason about recursive types containing projections,
+e.g. the following currently fails to compile even though it should be valid.
+```rust
+use std::borrow::Cow;
+pub struct Foo<'a>(Cow<'a, [Foo<'a>]>);
+```
+This issue has been known since at least 2015, see
+[#23714](https://github.com/rust-lang/rust/issues/23714) if you want to know more.
+
+### Explicitly checked implied bounds
+
+When checking an impl, we assume that the types in the impl headers are well-formed.
+This means that when using instantiating the impl we have to prove that's actually the case.
+[#100051](https://github.com/rust-lang/rust/issues/100051) shows that this is not the case.
+To fix this, we have to add `WF` predicates for the types in impl headers.
+Without coinduction for all traits, this even breaks `core`.
+
+```rust
+trait FromResidual<R> {}
+trait Try: FromResidual<<Self as Try>::Residual> {
+ type Residual;
+}
+
+struct Ready<T>(T);
+impl<T> Try for Ready<T> {
+ type Residual = Ready<()>;
+}
+impl<T> FromResidual<<Ready<T> as Try>::Residual> for Ready<T> {}
+```
+
+When checking that the impl of `FromResidual` is well formed we get the following cycle:
+
+The impl is well formed if `<Ready<T> as Try>::Residual` and `Ready<T>` are well formed.
+- `wf(<Ready<T> as Try>::Residual)` requires
+- `Ready<T>: Try`, which requires because of the super trait
+- `Ready<T>: FromResidual<Ready<T> as Try>::Residual>`, **because of implied bounds on impl**
+- `wf(<Ready<T> as Try>::Residual)` :tada: **cycle**
+
+### Issues when extending coinduction to more goals
+
+There are some additional issues to keep in mind when extending coinduction.
+The issues here are not relevant for the current solver.
+
+#### Implied super trait bounds
+
+Our trait system currently treats super traits, e.g. `trait Trait: SuperTrait`,
+by 1) requiring that `SuperTrait` has to hold for all types which implement `Trait`,
+and 2) assuming `SuperTrait` holds if `Trait` holds.
+
+Relying on 2) while proving 1) is unsound. This can only be observed in case of
+coinductive cycles. Without cycles, whenever we rely on 2) we must have also
+proven 1) without relying on 2) for the used impl of `Trait`.
+
+```rust
+trait Trait: SuperTrait {}
+
+impl<T: Trait> Trait for T {}
+
+// Keeping the current setup for coinduction
+// would allow this compile. Uff :<
+fn sup<T: SuperTrait>() {}
+fn requires_trait<T: Trait>() { sup::<T>() }
+fn generic<T>() { requires_trait::<T>() }
+```
+This is not really fundamental to coinduction but rather an existing property
+which is made unsound because of it.
+
+##### Possible solutions
+
+The easiest way to solve this would be to completely remove 2) and always elaborate
+`T: Trait` to `T: Trait` and `T: SuperTrait` outside of the trait solver.
+This would allow us to also remove 1), but as we still have to prove ordinary
+`where`-bounds on traits, that's just additional work.
+
+While one could imagine ways to disable cyclic uses of 2) when checking 1),
+at least the ideas of myself - @lcnr - are all far to complex to be reasonable.
+
+#### `normalizes_to` goals and progress
+
+A `normalizes_to` goal represents the requirement that `<T as Trait>::Assoc` normalizes
+to some `U`. This is achieved by defacto first normalizing `<T as Trait>::Assoc` and then
+equating the resulting type with `U`. It should be a mapping as each projection should normalize
+to exactly one type. By simply allowing infinite proof trees, we would get the following behavior:
+
+```rust
+trait Trait {
+ type Assoc;
+}
+
+impl Trait for () {
+ type Assoc = <() as Trait>::Assoc;
+}
+```
+
+If we now compute `normalizes_to(<() as Trait>::Assoc, Vec<u32>)`, we would resolve the impl
+and get the associated type `<() as Trait>::Assoc`. We then equate that with the expected type,
+causing us to check `normalizes_to(<() as Trait>::Assoc, Vec<u32>)` again.
+This just goes on forever, resulting in an infinite proof tree.
+
+This means that `<() as Trait>::Assoc` would be equal to any other type which is unsound.
+
+##### How to solve this
+
+**WARNING: THIS IS SUBTLE AND MIGHT BE WRONG**
+
+Unlike trait goals, `normalizes_to` has to be *productive*[^1]. A `normalizes_to` goal
+is productive once the projection normalizes to a rigid type constructor,
+so `<() as Trait>::Assoc` normalizing to `Vec<<() as Trait>::Assoc>` would be productive.
+
+A `normalizes_to` goal has two kinds of nested goals. Nested requirements needed to actually

+# Trait solving (new)
+
+This chapter describes how trait solving works with the new WIP solver located in
+[`rustc_trait_selection/solve`][solve]. Feel free to also look at the docs for
+[the current solver](../traits/resolution.md) and [the chalk solver](../traits/chalk.md)
+can be found separately.
+
+## Core concepts
+
+The goal of the trait system is to check whether a given trait bound is satisfied.
+Most notably when typechecking the body of - potentially generic - functions.
+For example:
+
+```rust
+fn uses_vec_clone<T: Clone>(x: Vec<T>) -> (Vec<T>, Vec<T>) {
+ (x.clone(), x)
+}
+```
+Here the call to `x.clone()` requires us to prove that `Vec<T>` implements `Clone` given
+the assumption that `T: Clone` is true. We can assume `T: Clone` as that will be proven by
+callers of this function.
+
+The concept of "prove the `Vec<T>: Clone` with the assumption `T: Clone`" is called a [`Goal`].
+Both `Vec<T>: Clone` and `T: Clone` are represented using [`Predicate`]. There are other
+predicates, most notably equality bounds on associated items: `<Vec<T> as IntoIterator>::Item == T`.
+See the `PredicateKind` enum for an exhaustive list. A `Goal` is represented as the `predicate` we
+have to prove and the `param_env` in which this predicate has to hold.
+
+We prove goals by checking whether each possible [`Candidate`] applies for the given goal by
+recursively proving its nested goals. For a list of possible candidates with examples, look at
+[`CandidateSource`]. The most important candidates are `Impl` candidates, i.e. trait implementations
+written by the user, and `ParamEnv` candidates, i.e. assumptions in our current environment.
+
+Looking at the above example, to prove `Vec<T>: Clone` we first use
+`impl<T: Clone> Clone for Vec<T>`. To use this impl we have to prove the nested
+goal that `T: Clone` holds. This can use the assumption `T: Clone` from the `ParamEnv`
+which does not have any nested goals. Therefore `Vec<T>: Clone` holds.
+
+The trait solver can either return success, ambiguity or an error as a [`CanonicalResponse`].
+For success and ambiguity it also returns constraints inference and region constraints.
+
+## Requirements
+
+Before we dive into the new solver lets first take the time to go through all of our requirements
+on the trait system. We can then use these to guide our design later on.
+
+TODO: elaborate on these rules and get more precise about their meaning.
+Also add issues where each of these rules have been broken in the past
+(or still are).
+
+### 1. The trait solver has to be *sound*
+
+This means that we must never return *success* for goals for which no `impl` exists. That would
+simply be unsound by assuming a trait is implemented even though it is not. When using predicates
+from the `where`-bounds, the `impl` will be proved by the user of the item.
+
+### 2. If type checker solves generic goal concrete instantiations of that goal have the same result
+
+Pretty much: If we successfully typecheck a generic function concrete instantiations
+of that function should also typeck. We should not get errors post-monomorphization.
+We can however get overflow as in the following snippet:
+
+```rust
+fn foo<T: Trait>(x: )
+```
+
+### 3. Trait goals in empty environments are proven by a unique impl
+
+If a trait goal holds with an empty environment, there is a unique `impl`,
+either user-defined or builtin, which is used to prove that goal.
+
+This is necessary for codegen to select a unique method.
+An exception here are *marker traits* which are allowed to overlap.
+
+### 4. Normalization in empty environments results in a unique type
+
+Normalization for alias types/consts has a unique result. Otherwise we can easily implement
+transmute in safe code. Given the following function, we have to make sure that the input and
+output types always get normalized to the same concrete type.
+```rust
+fn foo<T: Trait>(
+ x: <T as Trait>::Assoc
+) -> <T as Trait>::Assoc {
+ x
+}
+```
+
+### 5. During coherence trait solving has to be complete
+
+During coherence we never return *error* for goals which can be proven. This allows overlapping
+impls which would break rule 3.
+
+### 6. Trait solving must be (free) lifetime agnostic
+
+Trait solving during codegen should have the same result as during typeck. As we erase
+all free regions during codegen we must not rely on them during typeck. A noteworthy example
+is special behavior for `'static`.
+
+### 7. Removing ambiguity makes strictly more things compile
+
+We *should* not rely on ambiguity for things to compile.
+Not doing that will cause future improvements to be breaking changes.
+
+### 8. semantic equality implies structural equality
+
+Two types being equal in the type system must mean that they have the same `TypeId`.

+## Comparing types
+
+Because types are interned, it is possible to compare them for equality efficiently using `==`
+– however, this is almost never what you want to do unless you happen to be hashing and looking
+for duplicates. This is because often in Rust there are multiple ways to represent the same type,
+particularly once inference is involved.
+
+For example, the type `{integer}` (`ty::Infer(ty::IntVar(..))` an integer inference variable,
+the type of an integer literal like `0`) and `u8` (`ty::UInt(..)`) should often be treated as
+equal when testing whether they can be assigned to each other (which is a common operation in
+diagnostics code). `==` on them will return `false` though, since they are different types.
+
+The simplest way to compare two types correctly requires an inference context (`infcx`).
+If you have one, you can use `infcx.can_eq(param_env, ty1, ty2)`
+to check whether the types can be made equal.
+This is typically what you want to check during diagnostics, which is concerned with questions such
+as whether two types can be assigned to each other, not whether they're represented identically in
+the compiler's type-checking layer.
+
+When working with an inference context, you have to be careful to ensure that potential inference
+variables inside the types actually belong to that inference context. If you are in a function
+that has access to an inference context already, this should be the case. Specifically, this is the
+case during HIR type checking or MIR borrow checking.
+
+Another consideration is normalization. Two types may actually be the same, but one is behind an
+associated type. To compare them correctly, you have to normalize the types first. This is
+primarily a concern during HIR type checking and with all types from a `TyCtxt` query
+(for example from `tcx.type_of()`).
+
+When a `FnCtxt` or an `ObligationCtxt` is available during type checking, `.normalize(ty)`
+should be used on them to normalize the type. After type checking, diagnostics code can use
+`tcx.normalize_erasing_regions(ty)`.
+
+There are also cases where using `==` on `Ty` is fine. This is for example the case in late lints
+or after monomorphization, since type checking has been completed, meaning all inference variables
+are resolved and all regions have been erased. In these cases, if you know that inference variables
+or normalization won't be a concern, `#[allow]` or `#[expect]`ing the lint is recommended.
+
+When diagnostics code does not have access to an inference context, it should be threaded through
+the function calls if one is available in some place (like during type checking).
+
+If no inference context is available at all, then one can be created as described in
+[type-inference]. But this is only useful when the involved types (for example, if
+they came from a query like `tcx.type_of()`) are actually substituted with fresh
+inference variables using [`fresh_substs_for_item`]. This can be used to answer questions
+like "can `Vec<T>` for any `T` be unified with `Vec<u32>`?".

Linking to a Fuchsia checkout can help with debugging Fuchsia libraries,

+### Debugging the compiler test suite
+
+Debugging the compiler test suite requires some special configuration:
+
+First, we have to properly configure zxdb so it will be able to find debug
+symbols and source information for our test. The test runner can do this for us
+with:
+
+```sh
+src/ci/docker/scripts/fuchsia-test-runner.py debug \
+ --rust-src ${RUST_SRC_PATH} \
+ --fuchsia-src ${FUCHSIA_SRC_PATH} \
+ --test ${TEST}
+```
+
+where `${TEST}` is relative to Rust's `tests` directory (e.g. `ui/abi/...`).
+
+This will start a zxdb session that is properly configured for the specific test
+being run. All three arguments are optional, so you can omit `--fuchsia-src` if
+you don't have it downloaded. Now is a good time to set any desired breakpoints,
+like `b main`.
+
+Next, we have to tell `x.py` not to optimize or strip debug symbols from our
+test suite binaries. We can do this by passing some new arguments to `rustc`
+through our `x.py` invocation. The full invocation is:
+
+```sh

+#### else blocks (let-else statements)
+
+If a let statement contains an `else` component, also known as a let-else statement,
+then the `else` component should be formatted according to the same rules as the `else` block
+in [control flow expressions (i.e. if-else, and if-let-else expressions)](./expressions.md#control-flow-expressions).
+Apply the same formatting rules to the components preceding
+the `else` block (i.e. the `let pattern: Type = initializer_expr ...` portion)
+as described [above](#let-statements)
+
+Similarly to if-else expressions, if the initializer
+expression is multi-lined, then the `else` keyword and opening brace of the block (i.e. `else {`)
+should be put on the same line as the end of the initializer
+expression with a preceding space if all the following are true:
+
+* The initializer expression ends with one or more closing
+ parentheses, square brackets, and/or braces
+* There is nothing else on that line
+* That line is not indented beyond the indent of the first line containing the `let` keyword
+
+For example:
+
+```rust
+let Some(x) = y.foo(
+ "abc",
+ fairly_long_identifier,
+ "def",
+ "123456",
+ "string",
+ "cheese",
+) else {
+ bar()
+}
+```
+
+Otherwise, the `else` keyword and opening brace should be placed on the next line after the end of the initializer expression, and should not be indented (the `else` keyword should be aligned with the `let` keyword).
+
+For example:
+
+```rust
+let Some(x) = abcdef()
+ .foo(
+ "abc",
+ some_really_really_really_long_ident,
+ "ident",
+ "123456",
+ )
+ .bar()
+ .baz()
+ .qux("fffffffffffffffff")
+else {
+ foo_bar()
+}
+```
+
+##### Single line let-else statements
+
+The entire let-else statement may be formatted on a single line if all the following are true:
+
+* the entire statement is *short*
+* the `else` block contains a single-line expression and no statements
+* the `else` block contains no comments
+* the let statement components preceding the `else` block can be formatted on a single line
+
+```rust
+let Some(1) = opt else { return };
+
+let Some(1) = opt else {
+ return;
+};
+
+let Some(1) = opt else {
+ // nope
+ return
+};
+```
+
+Formatters may allow users to configure the value of the threshold
+used to determine whether a let-else statement is *short*.

+# `export-executable-symbols`
+
+The tracking issue for this feature is: [#84161](https://github.com/rust-lang/rust/issues/84161).
+
+------------------------
+
+The `-Zexport-executable-symbols` compiler flag makes `rustc` export symbols from executables. The resulting binary is runnable, but can also be used as a dynamic library. This is useful for interoperating with programs written in other languages, in particular languages with a runtime like Java or Lua.
+
+For example on windows:
+```rust
+#[no_mangle]
+fn my_function() -> usize {
+ return 42;
+}
+
+fn main() {
+ println!("Hello, world!");
+}
+```
+
+A standard `cargo build` will produce a `.exe` without an export directory. When the `export-executable-symbols` flag is added
+
+```Bash
+export RUSTFLAGS="-Zexport-executable-symbols"
+cargo build
+```
+
+the binary has an export directory with the functions:
+
+```plain
+The Export Tables (interpreted .edata section contents)
+
+...
+
+[Ordinal/Name Pointer] Table
+ [ 0] my_function
+ [ 1] main
+```
+(the output of `objdump -x` on the binary)
+
+Please note that the `#[no_mangle]` attribute is required. Without it, the symbol is not exported.
+
+The equivalent of this flag in C and C++ compilers is the `__declspec(dllexport)` annotation or the `-rdynamic` linker flag.

+
+------------------------
+
+Enable generation of NOP sleds for XRay function tracing instrumentation.
+For more information on XRay,
+read [LLVM documentation](https://llvm.org/docs/XRay.html),
+and/or the [XRay whitepaper](http://research.google.com/pubs/pub45287.html).
+
+Set the `-Z instrument-xray` compiler flag in order to enable XRay instrumentation.
+
+ - `-Z instrument-xray` – use the default settings
+ - `-Z instrument-xray=skip-exit` – configure a custom setting
+ - `-Z instrument-xray=ignore-loops,instruction-threshold=300` –
+ multiple settings separated by commas
+
+Supported options:
+
+ - `always` – force instrumentation of all functions
+ - `never` – do no instrument any functions
+ - `ignore-loops` – ignore presence of loops,
+ instrument functions based only on instruction count
+ - `instruction-threshold=10` – set a different instruction threshold for instrumentation
+ - `skip-entry` – do no instrument function entry
+ - `skip-exit` – do no instrument function exit
+
+The default settings are:
+
+ - instrument both entry & exit from functions
+ - instrument functions with at least 200 instructions,
+ or containing a non-trivial loop
+
+Note that `-Z instrument-xray` only enables generation of NOP sleds
+which on their own don't do anything useful.
+In order to actually trace the functions,
+you will need to link a separate runtime library of your choice,
+such as Clang's [XRay Runtime Library](https://www.llvm.org/docs/XRay.html#xray-runtime-library).

-very selectively, if at all.
+The `restriction` category should, *emphatically*, not be enabled as a whole. The contained
+lints may lint against perfectly reasonable code, may not have an alternative suggestion,
+and may contradict any other lints (including other categories). Lints should be considered
+on a case-by-case basis before enabling.

+[^restrict]: Some use cases for `restriction` lints include:
+ - Strict coding styles (e.g. [`clippy::else_if_without_else`]).
+ - Additional restrictions on CI (e.g. [`clippy::todo`]).
+ - Preventing panicking in certain functions (e.g. [`clippy::unwrap_used`]).
+ - Running a lint only on a subset of code (e.g. `#[forbid(clippy::float_arithmetic)]` on a module).

+### arithmetic-side-effects-allowed
+Suppress checking of the passed type names in all types of operations.
+
+If a specific operation is desired, consider using `arithmetic_side_effects_allowed_binary` or `arithmetic_side_effects_allowed_unary` instead.
+
+#### Example
+
+```toml
+arithmetic-side-effects-allowed = ["SomeType", "AnotherType"]
+```
+
+#### Noteworthy
+
+A type, say `SomeType`, listed in this configuration has the same behavior of
+`["SomeType" , "*"], ["*", "SomeType"]` in `arithmetic_side_effects_allowed_binary`.
+
+**Default Value:** `{}` (`rustc_data_structures::fx::FxHashSet<String>`)
+
+* [arithmetic_side_effects](https://rust-lang.github.io/rust-clippy/master/index.html#arithmetic_side_effects)
+
+
+### arithmetic-side-effects-allowed-binary
+Suppress checking of the passed type pair names in binary operations like addition or
+multiplication.
+
+Supports the "*" wildcard to indicate that a certain type won't trigger the lint regardless
+of the involved counterpart. For example, `["SomeType", "*"]` or `["*", "AnotherType"]`.
+
+Pairs are asymmetric, which means that `["SomeType", "AnotherType"]` is not the same as
+`["AnotherType", "SomeType"]`.
+
+#### Example
+
+```toml
+arithmetic-side-effects-allowed-binary = [["SomeType" , "f32"], ["AnotherType", "*"]]
+```
+
+**Default Value:** `[]` (`Vec<[String; 2]>`)
+
+* [arithmetic_side_effects](https://rust-lang.github.io/rust-clippy/master/index.html#arithmetic_side_effects)
+
+
+### arithmetic-side-effects-allowed-unary
+Suppress checking of the passed type names in unary operations like "negation" (`-`).
+
+#### Example
+
+```toml
+arithmetic-side-effects-allowed-unary = ["SomeType", "AnotherType"]
+```
+
+**Default Value:** `{}` (`rustc_data_structures::fx::FxHashSet<String>`)
+
+* [arithmetic_side_effects](https://rust-lang.github.io/rust-clippy/master/index.html#arithmetic_side_effects)

+A function or function pointer.
+
+Functions are the primary way code is executed within Rust. Function blocks, usually just
+called functions, can be defined in a variety of different places and be assigned many
+different attributes and modifiers.
+
+Standalone functions that just sit within a module not attached to anything else are common,
+but most functions will end up being inside [`impl`] blocks, either on another type itself, or
+as a trait impl for that type.
+
+```rust
+fn standalone_function() {
+ // code
+}
+
+pub fn public_thing(argument: bool) -> String {
+ // code
+ # "".to_string()
+}
+
+struct Thing {
+ foo: i32,
+}
+
+impl Thing {
+ pub fn new() -> Self {
+ Self {
+ foo: 42,
+ }
+ }
+}
+```
+
+In addition to presenting fixed types in the form of `fn name(arg: type, ..) -> return_type`,
+functions can also declare a list of type parameters along with trait bounds that they fall
+into.
+
+```rust
+fn generic_function<T: Clone>(x: T) -> (T, T, T) {
+ (x.clone(), x.clone(), x.clone())
+}
+
+fn generic_where<T>(x: T) -> T
+ where T: std::ops::Add<Output = T> + Copy
+{
+ x + x + x
+}
+```
+
+Declaring trait bounds in the angle brackets is functionally identical to using a `where`
+clause. It's up to the programmer to decide which works better in each situation, but `where`
+tends to be better when things get longer than one line.
+
+Along with being made public via `pub`, `fn` can also have an [`extern`] added for use in
+FFI.
+

+book] or the [Reference].

-/// Higher-order macro describing the server RPC API, allowing automatic
-/// generation of type-safe Rust APIs, both client-side and server-side.
-///
-/// `with_api!(MySelf, my_self, my_macro)` expands to:
-/// ```rust,ignore (pseudo-code)
-/// my_macro! {
-/// // ...
-/// Literal {
-/// // ...
-/// fn character(ch: char) -> MySelf::Literal;
-/// // ...
-/// fn span(my_self: &MySelf::Literal) -> MySelf::Span;
-/// fn set_span(my_self: &mut MySelf::Literal, span: MySelf::Span);
-/// },
-/// // ...
-/// }
-/// ```
-///
-/// The first two arguments serve to customize the arguments names
-/// and argument/return types, to enable several different usecases:
-///
-/// If `my_self` is just `self`, then each `fn` signature can be used
-/// as-is for a method. If it's anything else (`self_` in practice),
-/// then the signatures don't have a special `self` argument, and
-/// can, therefore, have a different one introduced.
-///
-/// If `MySelf` is just `Self`, then the types are only valid inside
-/// a trait or a trait impl, where the trait has associated types
-/// for each of the API types. If non-associated types are desired,
-/// a module name (`self` in practice) can be used instead of `Self`.

//! idea here is that people who do not use Cargo, can instead teach their build
//! system to generate `rust-project.json` which can be ingested by
//! rust-analyzer.
+//!
+//! This short file is a somewhat big conceptual piece of the architecture of
+//! rust-analyzer, so it's worth elaborating on the underlying ideas and
+//! motivation.
+//!
+//! For rust-analyzer to function, it needs some information about the project.
+//! Specifically, it maintains an in-memory data structure which lists all the
+//! crates (compilation units) and dependencies between them. This is necessary
+//! a global singleton, as we do want, eg, find usages to always search across
+//! the whole project, rather than just in the "current" crate.
+//!
+//! Normally, we get this "crate graph" by calling `cargo metadata
+//! --message-format=json` for each cargo workspace and merging results. This
+//! works for your typical cargo project, but breaks down for large folks who
+//! have a monorepo with an infinite amount of Rust code which is built with bazel or
+//! some such.
+//!
+//! To support this use case, we need to make _something_ configurable. To avoid
+//! a [midlayer mistake](https://lwn.net/Articles/336262/), we allow configuring
+//! the lowest possible layer. `ProjectJson` is essentially a hook to just set
+//! that global singleton in-memory data structure. It is optimized for power,
+//! not for convenience (you'd be using cargo anyway if you wanted nice things,
+//! right? :)
+//!
+//! `rust-project.json` also isn't necessary a file. Architecturally, we support
+//! any convenient way to specify this data, which today is:
+//!
+//! * file on disk
+//! * a field in the config (ie, you can send a JSON request with the contents
+//! of rust-project.json to rust-analyzer, no need to write anything to disk)
+//!
+//! Another possible thing we don't do today, but which would be totally valid,
+//! is to add an extension point to VS Code extension to register custom
+//! project.
+//!
+//! In general, it is assumed that if you are going to use `rust-project.json`,
+//! you'd write a fair bit of custom code gluing your build system to ra through
+//! this JSON format. This logic can take form of a VS Code extension, or a
+//! proxy process which injects data into "configure" LSP request, or maybe just
+//! a simple build system rule to generate the file.
+//!
+//! In particular, the logic for lazily loading parts of the monorepo as the
+//! user explores them belongs to that extension (it's totally valid to change
+//! rust-project.json over time via configuration request!)

-=== Emacs
+=== VS Code or VSCodium in Flatpak
+
+Setting up `rust-analyzer` with a Flatpak version of Code is not trivial because of the Flatpak sandbox.
+While the sandbox can be disabled for some directories, `/usr/bin` will always be mounted under `/run/host/usr/bin`.
+This prevents access to the system's C compiler, a system-wide installation of Rust, or any other libraries you might want to link to.
+Some compilers and libraries can be acquired as Flatpak SDKs, such as `org.freedesktop.Sdk.Extension.rust-stable` or `org.freedesktop.Sdk.Extension.llvm15`.
+
+If you use a Flatpak SDK for Rust, there should be no extra steps necessary.
-Note this excellent https://robert.kra.hn/posts/2021-02-07_rust-with-emacs/[guide] from https://github.com/rksm[@rksm].
+If you want to use Flatpak in combination with `rustup`, the following steps might help:
+
+ - both Rust and `rustup` have to be installed using https://rustup.rs. Distro packages _will not_ work.
+ - you need to launch Code, open a terminal and run `echo $PATH`
+ - using https://flathub.org/apps/details/com.github.tchx84.Flatseal[Flatseal], you must add an environment variable called `PATH`.
+ Set its value to the output from above, appending `:~/.cargo/bin`, where `~` is the path to your home directory.
+ You must replace `~`, as it won't be expanded otherwise.
+ - while Flatseal is open, you must enable access to "All user files"
+
+A C compiler should already be available via `org.freedesktop.Sdk`.
+Any other tools or libraries you will need to acquire from Flatpak.
+
+=== Emacs
Prerequisites: You have installed the <<rust-analyzer-language-server-binary,`rust-analyzer` binary>>.
-Emacs support is maintained as part of the https://github.com/emacs-lsp/lsp-mode[Emacs-LSP] package in https://github.com/emacs-lsp/lsp-mode/blob/master/lsp-rust.el[lsp-rust.el].
+To use `rust-analyzer`, you need to install and enable one of the two popular two popular LSP client implementations for Emacs, https://github.com/joaotavora/eglot[Eglot] or https://github.com/emacs-lsp/lsp-mode[LSP Mode]. Both enable `rust-analyzer` by default in rust buffers if it is available.
+
+==== Eglot
+
+Eglot is the more minimalistic and lightweight LSP client for Emacs, integrates well with existing Emacs functionality and will be built into Emacs starting from release 29.
+
+After installing Eglot, e.g. via `M-x package-install` (not needed from Emacs 29), you can enable it via the `M-x eglot` command or load it automatically in `rust-mode` via
+
+[source,emacs-lisp]
+----
+(add-hook 'rust-mode-hook 'eglot-ensure)
+----
+
+For more detailed instructions and options see the https://joaotavora.github.io/eglot[Eglot manual] (also available from Emacs via `M-x info`) and the
+https://github.com/joaotavora/eglot/blob/master/README.md[Eglot readme].
+
+Eglot does not support the rust-analyzer extensions to the language-server protocol and does not aim to do so in the future. The https://github.com/nemethf/eglot-x#rust-analyzer-extensions[eglot-x] package adds experimental support for those LSP extensions.
+
+==== LSP Mode
+
+LSP-mode is the original LSP-client for emacs. Compared to Eglot it has a larger codebase and supports more features, like LSP protocol extensions.
+With extension packages like https://github.com/emacs-lsp/lsp-mode[LSP UI] it offers a lot of visual eyecandy.
+Further it integrates well with https://github.com/emacs-lsp/dap-mode[DAP mode] for support of the Debug Adapter Protocol.
+
+You can install LSP-mode via `M-x package-install` and then run it via the `M-x lsp` command or load it automatically in rust buffers with
+
+[source,emacs-lisp]
+----
+(add-hook 'rust-mode-hook 'lsp-deferred)

+
+For more information on how to set up LSP mode and its extension package see the instructions in the https://emacs-lsp.github.io/lsp-mode/page/installation[LSP mode manual].
+Also see the https://emacs-lsp.github.io/lsp-mode/page/lsp-rust-analyzer/[rust-analyzer section] for `rust-analyzer` specific options and commands, which you can optionally bind to keys.
-1. Install the most recent version of `emacs-lsp` package by following the https://github.com/emacs-lsp/lsp-mode[Emacs-LSP instructions].
-2. Set `lsp-rust-server` to `'rust-analyzer`.
-3. Run `lsp` in a Rust buffer.
-4. (Optionally) bind commands like `lsp-rust-analyzer-join-lines`, `lsp-extend-selection` and `lsp-rust-analyzer-expand-macro` to keys.
+Note the excellent https://robert.kra.hn/posts/2021-02-07_rust-with-emacs/[guide] from https://github.com/rksm[@rksm] on how to set-up Emacs for Rust development with LSP mode and several other packages.

While most errors and warnings provided by rust-analyzer come from the `cargo check` integration, there's a growing number of diagnostics implemented using rust-analyzer's own analysis.
Some of these diagnostics don't respect `\#[allow]` or `\#[deny]` attributes yet, but can be turned off using the `rust-analyzer.diagnostics.enable`, `rust-analyzer.diagnostics.experimental.enable` or `rust-analyzer.diagnostics.disabled` settings.

## [Unreleased]
+## [1.5.2] 2023-01-24
+
+### Fixed
+
+- Resolve issue when comments are found within const generic defaults in unit structs [#5668](https://github.com/rust-lang/rustfmt/issues/5668)
+- Resolve issue when block comments are found within trait generics [#5358](https://github.com/rust-lang/rustfmt/issues/5358)
+- Correctly handle alignment of comments containing unicode characters [#5504](https://github.com/rust-lang/rustfmt/issues/5504)
+- Properly indent a single generic bound that requires being written across multiple lines [#4689](https://github.com/rust-lang/rustfmt/issues/4689) (n.b. this change is version gated and will only appear when the `version` configuration option is set to `Two`)
+
+### Changed
+
+- Renamed `fn_args_layout` configuration option to `fn_params_layout` [#4149](https://github.com/rust-lang/rustfmt/issues/4149). Note that `fn_args_layout` has only been soft deprecated: `fn_args_layout` will continue to work without issue, but rustfmt will display a warning to encourage users to switch to the new name
+
+### Added
+
+- New configuration option (`skip_macro_invocations`)[https://rust-lang.github.io/rustfmt/?version=master&search=#skip_macro_invocations] [#5347](https://github.com/rust-lang/rustfmt/pull/5347) that can be used to globally define a single enumerated list of macro calls that rustfmt should skip formatting. rustfmt [currently also supports this via a custom tool attribute](https://github.com/rust-lang/rustfmt#tips), however, these cannot be used in all contexts because [custom inner attributes are unstable](https://github.com/rust-lang/rust/issues/54726)
+
+### Misc
+
+- rustfmt now internally supports the ability to have both stable and unstable variants of a configuration option [#5378](https://github.com/rust-lang/rustfmt/issues/5378). This ability will allow the rustfmt team to make certain configuration options available on stable toolchains more quickly because we no longer have to wait for _every_ variant to be stable-ready before stabilizing _any_ variant.
+
+### Install/Download Options
+- **rustup (nightly)** - nightly-2023-01-24
+- **GitHub Release Binaries** - [Release v1.5.2](https://github.com/rust-lang/rustfmt/releases/tag/v1.5.2)
+- **Build from source** - [Tag v1.5.2](https://github.com/rust-lang/rustfmt/tree/v1.5.2), see instructions for how to [install rustfmt from source][install-from-source]

**N.B** A bug was introduced in v1.5.0/nightly-2022-06-15 which modified formatting. If you happened to run rustfmt over your code with one of those ~10 nightlies it's possible you may have seen formatting changes, and you may see additional changes after this fix since that bug has now been reverted.

+[![Coverage Status](https://coveralls.io/repos/github/gimli-rs/addr2line/badge.svg?branch=master)](https://coveralls.io/github/gimli-rs/addr2line?branch=master)
+
+A cross-platform library for retrieving per-address debug information
+from files with DWARF debug information.
+
+`addr2line` uses [`gimli`](https://github.com/gimli-rs/gimli) to parse
+the debug information, and exposes an interface for finding
+the source file, line number, and wrapping function for instruction
+addresses within the target program. These lookups can either be
+performed programmatically through `Context::find_location` and
+`Context::find_frames`, or via the included example binary,
+`addr2line` (named and modelled after the equivalent utility from
+[GNU binutils](https://sourceware.org/binutils/docs/binutils/addr2line.html)).
+
+# Quickstart
+ - Add the [`addr2line` crate](https://crates.io/crates/addr2line) to your `Cargo.toml`
+ - Load the file and parse it with [`addr2line::object::read::File::parse`](https://docs.rs/object/*/object/read/struct.File.html#method.parse)
+ - Pass the parsed file to [`addr2line::Context::new` ](https://docs.rs/addr2line/*/addr2line/struct.Context.html#method.new)
+ - Use [`addr2line::Context::find_location`](https://docs.rs/addr2line/*/addr2line/struct.Context.html#method.find_location)
+ or [`addr2line::Context::find_frames`](https://docs.rs/addr2line/*/addr2line/struct.Context.html#method.find_frames)
+ to look up debug information for an address
+
+# Performance
+
+`addr2line` optimizes for speed over memory by caching parsed information.
+The DWARF information is parsed lazily where possible.
+
+The library aims to perform similarly to equivalent existing tools such

+//! This crate provides a cross-platform library and binary for translating addresses into
+//! function names, file names and line numbers. Given an address in an executable or an
+//! offset in a section of a relocatable object, it uses the debugging information to
+//! figure out which file name and line number are associated with it.
+//!
+//! When used as a library, files must first be loaded using the
+//! [`object`](https://github.com/gimli-rs/object) crate.
+//! A context can then be created with [`Context::new`](./struct.Context.html#method.new).
+//! The context caches some of the parsed information so that multiple lookups are
+//! efficient.
+//! Location information is obtained with
+//! [`Context::find_location`](./struct.Context.html#method.find_location) or
+//! [`Context::find_location_range`](./struct.Context.html#method.find_location_range).
+//! Function information is obtained with
+//! [`Context::find_frames`](./struct.Context.html#method.find_frames), which returns
+//! a frame for each inline function. Each frame contains both name and location.
+//!
+//! The crate has an example CLI wrapper around the library which provides some of
+//! the functionality of the `addr2line` command line tool distributed with [GNU
+//! binutils](https://www.gnu.org/software/binutils/).
+//!
+//! Currently this library only provides information from the DWARF debugging information,
+//! which is parsed using [`gimli`](https://github.com/gimli-rs/gimli). The example CLI
+//! wrapper also uses symbol table information provided by the `object` crate.

+
+_🎵 Immutability never bothered me anyway 🎶_
+
+This crate provides various "frozen" collections.
+
+These are append-only collections where references to entries can be held on to even across insertions. This is safe because these collections only support storing data that's present behind some indirection -- i.e. `String`, `Vec<T>`, `Box<T>`, etc, and they only yield references to the data behind the allocation (`&str`, `&[T]`, and `&T` respectively)
+
+The typical use case is having a global cache of strings or other data which the rest of the program borrows from.
+
+### Running all examples
+
+```bash
+cargo test --examples --features indexmap
+```

+//! This crate provides various "Frozen" collections.

+//! These are append-only collections where references to entries can be held
+//! on to even across insertions. This is safe because these collections only
+//! support storing data that's present behind some indirection -- i.e. `String`,
+//! `Vec<T>`, `Box<T>`, etc, and they only yield references to the data behind the
+//! allocation (`&str`, `&[T]`, and `&T` respectively)
+//!
+//! The typical use case is having a global cache of strings or other data which the rest of the program borrows from.

+ `Format`, version or address size parameters to accept an `Encoding`
+ parameter instead.
+ Notable changes are `LocationLists::locations`, `RangeLists::ranges`,
+ and `Expression::evaluation`.
+ [#364](https://github.com/gimli-rs/gimli/pull/364)

+ of byte arrays.
+ [#365](https://github.com/gimli-rs/gimli/pull/365)
+
+* Replaced `EvaluationResult::TextBase` with
+ `EvaluationResult::RequiresRelocatedAddress`. The handling of `TextBase`
+ was incorrect.
+ [#335](https://github.com/gimli-rs/gimli/pull/335)
+
+* Added `EvaluationResult::IndexedAddress` for operations that require an
+ address from `.debug_addr`.
+ [#358](https://github.com/gimli-rs/gimli/pull/358)
+
+* Added `Reader::read_slice`. Added a default implementation of
+ `Reader::read_u8_array` which uses this.
+ [#358](https://github.com/gimli-rs/gimli/pull/358)
+
+### Added
+
+* Added initial support for writing DWARF. This is targeted at supporting
+ line number information only.
+ [#340](https://github.com/gimli-rs/gimli/pull/340)
+ [#344](https://github.com/gimli-rs/gimli/pull/344)

+ and `DW_FORM_loclistx` attributes.
+ [#358](https://github.com/gimli-rs/gimli/pull/358)
+
+* Added high level `Dwarf` and `Unit` types. Existing code does not need to
+ switch to using these types, but doing so will make DWARF 5 support simpler.
+ [#352](https://github.com/gimli-rs/gimli/pull/352)
+ [#380](https://github.com/gimli-rs/gimli/pull/380)
+ [#381](https://github.com/gimli-rs/gimli/pull/381)
+
+* Added `EhFrame::set_address_size` and `DebugFrame::set_address_size` methods

+ the native size.
+ [#325](https://github.com/gimli-rs/gimli/pull/325)
+
+* Added architecture specific definitions for `Register` values and names.
+ Changed dwarfdump to print them.

+ [#323](https://github.com/gimli-rs/gimli/pull/323)
+
+* Changed `LineRows` to be covariant in its `Reader` type parameter.
+ [#324](https://github.com/gimli-rs/gimli/pull/324)

+
+Released 2018/06/01.
+
+### Added

+ crate is available. Disable the "std" feature and enable the "alloc"
+ feature. [#138][] [#271][]

+
+* A `dwarf-validate` example program that checks the integrity of the given
+ DWARF and its references between sections. [#290][]
+
+* Added the `EndianReader<T>` type, an easy way to define a custom `Reader`
+ implementation with a reference to a generic buffer of bytes and an associated
+ endianity. [#298][] [#302][]
+
+### Changed
+
+* Various speed improvements for evaluating `.debug_line` line number
+ programs. [#276][]
+
+* The example `dwarfdump` clone is a [whole lot faster

+
+* `EndianBuf` has been renamed to `EndianSlice`, use that name instead. [#295][]
+
+### Fixed
+
+* Evaluating the `DW_CFA_restore_state` opcode properly maintains the current
+ location. Previously it would incorrectly restore the old location when
+ popping from evaluation stack. [#274][]

+
+--------------------------------------------------------------------------------
+
+## 0.15.0
+
+Released 2017/12/01.
+
+### Added
+
+* Added the `EndianBuf::to_string()` method. [#233][]
+
+* Added more robust error handling in our example `dwarfdump` clone. [#234][]
+
+* Added `FrameDescriptionEntry::initial_address` method. [#237][]
+
+* Added `FrameDescriptionEntry::len` method. [#237][]
+
+* Added the `FrameDescriptionEntry::entry_len` method. [#241][]
+
+* Added the `CommonInformationEntry::offset` method. [#241][]
+
+* Added the `CommonInformationEntry::entry_len` method. [#241][]
+
+* Added the `CommonInformationEntry::version` method. [#241][]
+
+* Added the `CommonInformationEntry::augmentation` method. [#241][]
+
+* Added the `CommonInformationEntry::code_alignment_factor` method. [#241][]
+
+* Added the `CommonInformationEntry::data_alignment_factor` method. [#241][]
+
+* Added the `CommonInformationEntry::return_address_register` method. [#241][]
+
+* Added support for printing `.eh_frame` sections to our example `dwarfdump`
+ clone. [#241][]
+
+* Added support for parsing the `.eh_frame_hdr` section. On Linux, the
+ `.eh_frame_hdr` section provides a pointer to the already-mapped-in-memory
+ `.eh_frame` data, so that it doesn't need to be duplicated, and a binary
+ search table of its entries for faster unwinding information lookups. [#250][]
+
+* Added support for parsing DWARF 5 compilation unit headers. [#257][]
+
+* Added support for DWARF 5's `DW_FORM_implicit_const`. [#257][]
+
+### Changed
+
+* Unwinding methods now give ownership of the unwinding context back to the
+ caller if errors are encountered, not just on the success path. This allows
+ recovering from errors in signal-safe code, where constructing a new unwinding
+ context is not an option because it requires allocation. This is a **breaking
+ change** affecting `UnwindSection::unwind_info_for_address` and
+ `UninitializedUnwindContext::initialize`. [#241][]
+
+* `CfaRule` and `RegisterRule` now expose their `DW_OP` expressions as
+ `Expression`. This is a minor **breaking change**. [#241][]
+
+* The `Error::UnknownVersion` variant now contains the unknown version
+ number. This is a minor **breaking change**. [#245][]
+
+* `EvaluationResult::RequiresEntryValue` requires an `Expression` instead of a
+ `Reader` now. This is a minor **breaking change**. [#256][]

+
+--------------------------------------------------------------------------------
+
+## 0.14.0
+
+Released 2017/08/08.
+
+### Added
+
+* All `pub` types now `derive(Hash)`. [#192][]
+
+* All the constants from DWARF 5 are now defined. [#193][]
+
+* Added support for the `DW_OP_GNU_parameter_ref` GNU extension to parsing and
+ evaluation DWARF opcodes. [#208][]
+
+* Improved LEB128 parsing performance. [#216][]
+
+* Improved `.debug_{aranges,pubnames,pubtypes}` parsing performance. [#218][]
+
+* Added the ability to choose endianity dynamically at run time, rather than
+ only statically at compile time. [#219][]
+
+### Changed
+
+* The biggest change of this release is that `gimli` no longer requires the
+ object file's section be fully loaded into memory. This enables using `gimli`
+ on 32 bit platforms where there often isn't enough contiguous virtual memory
+ address space to load debugging information into. The default behavior is
+ still geared for 64 bit platforms, where address space overfloweth, and you
+ can still load the whole sections of the object file (or the entire object
+ file) into memory. This is abstracted over with the `gimli::Reader`
+ trait. This manifests as small (but many) breaking changes to much of the
+ public API. [#182][]
+
+### Fixed
+
+* The `DW_END_*` constants for defining endianity of a compilation unit were
+ previously incorrect. [#193][]
+
+* The `DW_OP_addr` opcode is relative to the base address of the `.text` section
+ of the binary, but we were incorrectly treating it as an absolute value. [#210][]

+# Contributing to `gimli`
+
+Hi! We'd love to have your contributions! If you want help or mentorship, reach
+out to us in a GitHub issue, or ping `fitzgen` in `#rust` on `irc.mozilla.org`.

+
+## <a id="coc"></a> Code of Conduct
+
+We abide by the
+[Rust Code of Conduct](https://www.rust-lang.org/en-US/conduct.html) and ask
+that you do as well.
+
+## <a id="issues"></a> Filing an Issue
+
+Think you've found a bug? File an issue! To help us understand and reproduce the
+issue, provide us with:
+
+* The (preferably minimal) test case
+* Steps to reproduce the issue using the test case
+* The expected result of following those steps
+* The actual result of following those steps
+
+Definitely file an issue if you see an unexpected panic originating from within
+`gimli`! `gimli` should never panic unless it is explicitly documented to panic
+in the specific circumstances provided.
+
+## <a id="building"></a> Building `gimli`
+
+`gimli` should always build on stable `rustc`, but we recommend using
+[`rustup`](https://www.rustup.rs/) so you can switch to nightly `rustc` and run
+benchmarks.
+
+To build `gimli`:
+
+```
+$ cargo build
+```
+
+## <a id="testing"></a> Testing `gimli`
+
+Run the tests with `cargo`:
+
+```
+$ cargo test
+```
+
+### <a id="coverage"></a> Test Coverage
+
+If you have `kcov` installed under linux, then you can generate code coverage
+results using the `coverage` script in the root of the repository, and view them
+at `target/kcov/index.html`. Otherwise you can create a pull request and view
+the coverage results on coveralls.io.
+
+```
+$ ./coverage
+```
+
+The ideal we aim to reach is having our unit tests exercise every branch in
+`gimli`. We allow an exception for branches which propagate errors inside a
+`try!(..)` invocation, but we *do* want to exercise the original error paths.
+
+Pull requests adding new code should ensure that this ideal is met.
+
+At the time of writing we have 94% test coverage according to our coveralls.io
+continuous integration. That number should generally stay the same or go up ;)
+This is a bit subjective, because -.001% is just noise and doesn't matter.
+
+### <a id="test-assembler"></a> Using `test-assembler`
+
+We use the awesome
+[`test-assembler`](https://github.com/luser/rust-test-assembler) crate to
+construct binary test data. It makes building complex test cases readable.
+
+[Here is an example usage in `gimli`](https://github.com/gimli-rs/gimli/blob/156451f3fe6eeb2fa62b84b362c33fcb176e1171/src/loc.rs#L263)
+
+### <a id="fuzzing"></a> Fuzzing
+
+First, install `cargo fuzz`:
+
+```
+$ cargo install cargo-fuzz
+```
+
+Optionally, [set up the corpora for our fuzz targets by following these
+instructions](https://github.com/gimli-rs/gimli-libfuzzer-corpora/blob/master/README.md#using-these-corpora).
+
+Finally, run a fuzz target! In this case, we are running the `eh_frame` fuzz
+target:
+
+```
+$ cargo fuzz run eh_frame
+```
+
+The fuzz target definitions live in `fuzz/fuzz_targets/*`. You can add new ones
+via `cargo fuzz add <my_new_target>`.
+
+## <a id="benchmarking"></a> Benchmarking
+
+The benchmarks require nightly `rustc`, so use `rustup`:
+
+```
+$ rustup run nightly cargo bench
+```
+
+We aim to be the fastest DWARF library. Period.
+
+Please provide before and after benchmark results with your pull requests. You
+may also find [`cargo benchcmp`](https://github.com/BurntSushi/cargo-benchcmp)
+handy for comparing results.
+
+Pull requests adding `#[bench]` micro-benchmarks that exercise a new edge case
+are very welcome!
+
+## <a id="style"></a> Style
+
+We use `rustfmt` to automatically format and style all of our code.
+
+To install `rustfmt`:
+
+```
+$ rustup component add rustfmt-preview
+```
+
+To run `rustfmt` on `gimli`:
+
+```
+$ cargo fmt
+```

+
+[![](https://img.shields.io/crates/v/gimli.svg) ![](https://img.shields.io/crates/d/gimli.svg)](https://crates.io/crates/gimli)
+[![](https://docs.rs/gimli/badge.svg)](https://docs.rs/gimli/)
+[![Build Status](https://github.com/gimli-rs/gimli/workflows/Rust/badge.svg)](https://github.com/gimli-rs/gimli/actions)
+[![Coverage Status](https://coveralls.io/repos/github/gimli-rs/gimli/badge.svg?branch=master)](https://coveralls.io/github/gimli-rs/gimli?branch=master)
+
+`gimli` is a blazing fast library for consuming the
+[DWARF debugging format](https://dwarfstd.org/).
+
+* **Zero copy:** everything is just a reference to the original input buffer. No
+ copies of the input data get made.
+
+* **Lazy:** you can iterate compilation units without parsing their
+ contents. Parse only as many debugging information entry (DIE) trees as you
+ iterate over. `gimli` also uses `DW_AT_sibling` references to avoid parsing a
+ DIE's children to find its next sibling, when possible.
+
+* **Cross-platform:** `gimli` makes no assumptions about what kind of object
+ file you're working with. The flipside to that is that it's up to you to
+ provide an ELF loader on Linux or Mach-O loader on macOS.
+
+ * Unsure which object file parser to use? Try the cross-platform
+ [`object`](https://github.com/gimli-rs/object) crate. See the
+ [`examples/`](./examples) directory for usage with `gimli`.
+
+## Install
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+gimli = "0.26.2"
+```
+
+The minimum supported Rust version is 1.42.0.
+
+## Documentation
+
+* [Documentation on docs.rs](https://docs.rs/gimli/)
+
+* Example programs:
+
+ * [A simple `.debug_info` parser](./examples/simple.rs)
+
+ * [A simple `.debug_line` parser](./examples/simple_line.rs)
+
+ * [A `dwarfdump` clone](./examples/dwarfdump.rs)
+
+ * [An `addr2line` clone](https://github.com/gimli-rs/addr2line)
+
+ * [`ddbug`](https://github.com/gimli-rs/ddbug), a utility giving insight into
+ code generation by making debugging information readable.
+
+ * [`dwprod`](https://github.com/fitzgen/dwprod), a tiny utility to list the
+ compilers used to create each compilation unit within a shared library or
+ executable (via `DW_AT_producer`).
+
+ * [`dwarf-validate`](./examples/dwarf-validate.rs), a program to validate the
+ integrity of some DWARF and its references between sections and compilation
+ units.
+
+## License
+

+# What are these files?
+
+These files are the DWARF data generated for (an early version of) this
+library. Each file corresponds is a section from the built library's object
+file. By splitting the sections out to their own files, we don't need to worry
+about cross platform and cross object file format issues when running examples.
+
+# Updating and adding new sections
+
+## macOS
+
+Use `otool` to list the sections of a binary:
+
+```
+$ otool -l path/to/binary
+```
+
+You should see output similar to this:
+
+```
+Load command 0
+ cmd LC_SEGMENT_64
+ cmdsize 72
+ segname __PAGEZERO
+ vmaddr 0x0000000000000000
+ vmsize 0x0000000100000000
+ fileoff 0
+ filesize 0
+ maxprot 0x00000000
+ initprot 0x00000000
+ nsects 0
+ flags 0x0
+Load command 1
+ cmd LC_SEGMENT_64

+ vmsize 0x00000000001b7000
+ fileoff 0
+ filesize 1798144
+ maxprot 0x00000007
+ initprot 0x00000005
+ nsects 8
+ flags 0x0
+Section
+ sectname __text
+ segname __TEXT
+ addr 0x0000000100000a50
+ size 0x0000000000170716
+ offset 2640
+ align 2^4 (16)
+ reloff 0
+ nreloc 0
+ flags 0x80000400
+ reserved1 0
+ reserved2 0
+```
+
+Etc.
+
+Find the `Section` entry of the section you'd like to isolate. For example, if
+you're looking for `eh_frame`, find an entry like this:
+
+```
+Section
+ sectname __eh_frame
+ segname __TEXT
+ addr 0x0000000100192f38
+ size 0x00000000000240c8
+ offset 1650488
+ align 2^3 (8)
+ reloff 0
+ nreloc 0
+ flags 0x00000000
+ reserved1 0
+ reserved2 0
+```
+
+Then use `dd` to copy `size` bytes starting from `offset`:
+
+```
+$ dd bs=1 skip=1650488 count=$(printf "%d" 0x00000000000240c8) if=path/to/binary of=fixtures/self/eh_frame
+```
+
+Finally, use `otool` and `hexdump` to verify that the isolated section has the
+same data as the section within the binary:
+
+```
+$ otool -s __TEXT __eh_frame path/to/binary | head
+path/to/binary:

+//! `gimli` is a library for reading and writing the
+//! [DWARF debugging format](https://dwarfstd.org/).
+//!
+//! See the [read](./read/index.html) and [write](./write/index.html) modules
+//! for examples and API documentation.
+//!
+//! ## Cargo Features
+//!
+//! Cargo features that can be enabled with `gimli`:
+//!
+//! * `std`: Enabled by default. Use the `std` library. Disabling this feature
+//! allows using `gimli` in embedded environments that do not have access to
+//! `std`. Note that even when `std` is disabled, `gimli` still requires an
+//! implementation of the `alloc` crate.
+//!
+//! * `read`: Enabled by default. Enables the `read` module. Use of `std` is
+//! optional.
+//!
+//! * `write`: Enabled by default. Enables the `write` module. Always uses
+//! the `std` library.

+/// Note that the whole original buffer is kept alive in memory even if there is

+/// long as `MmapFile` dereferences to the underlying `[u8]` data.

+//! # fn example() -> Result<(), gimli::Error> {
+//! # type R = gimli::EndianSlice<'static, gimli::LittleEndian>;
+//! # let get_file_section_reader = |name| -> Result<R, gimli::Error> { unimplemented!() };
+//! # let get_sup_file_section_reader = |name| -> Result<R, gimli::Error> { unimplemented!() };
+//! // Read the DWARF sections with whatever object loader you're using.
+//! // These closures should return a `Reader` instance (e.g. `EndianSlice`).
+//! let loader = |section: gimli::SectionId| { get_file_section_reader(section.name()) };
+//! let sup_loader = |section: gimli::SectionId| { get_sup_file_section_reader(section.name()) };
+//! let mut dwarf = gimli::Dwarf::load(loader)?;
+//! dwarf.load_sup(sup_loader)?;
+//!
+//! // Iterate over all compilation units.
+//! let mut iter = dwarf.units();
+//! while let Some(header) = iter.next()? {
+//! // Parse the abbreviations and other information for this compilation unit.
+//! let unit = dwarf.unit(header)?;
+//!
+//! // Iterate over all of this compilation unit's entries.
+//! let mut entries = unit.entries();
+//! while let Some((_, entry)) = entries.next_dfs()? {
+//! // If we find an entry for a function, print it.
+//! if entry.tag() == gimli::DW_TAG_subprogram {
+//! println!("Found a function: {:?}", entry);
+//! }
+//! }
+//! }
+//! # unreachable!()
+//! # }
+//! ```

+//! executable (via `DW_AT_producer`)
+//!
+//! * [`dwarf-validate`](https://github.com/gimli-rs/gimli/blob/master/examples/dwarf-validate.rs),
+//! a program to validate the integrity of some DWARF and its references
+//! between sections and compilation units.
+//!
+//! ## API Structure
+//!
+//! * Basic familiarity with DWARF is assumed.
+//!
+//! * The [`Dwarf`](./struct.Dwarf.html) type contains the commonly used DWARF
+//! sections. It has methods that simplify access to debugging data that spans
+//! multiple sections. Use of this type is optional, but recommended.
+//!
+//! * Each section gets its own type. Consider these types the entry points to
+//! the library:
+//!
+//! * [`DebugAbbrev`](./struct.DebugAbbrev.html): The `.debug_abbrev` section.
+//!
+//! * [`DebugAddr`](./struct.DebugAddr.html): The `.debug_addr` section.
+//!
+//! * [`DebugAranges`](./struct.DebugAranges.html): The `.debug_aranges`
+//! section.
+//!
+//! * [`DebugFrame`](./struct.DebugFrame.html): The `.debug_frame` section.
+//!
+//! * [`DebugInfo`](./struct.DebugInfo.html): The `.debug_info` section.
+//!
+//! * [`DebugLine`](./struct.DebugLine.html): The `.debug_line` section.
+//!
+//! * [`DebugLineStr`](./struct.DebugLineStr.html): The `.debug_line_str` section.
+//!
+//! * [`DebugLoc`](./struct.DebugLoc.html): The `.debug_loc` section.
+//!
+//! * [`DebugLocLists`](./struct.DebugLocLists.html): The `.debug_loclists` section.
+//!
+//! * [`DebugPubNames`](./struct.DebugPubNames.html): The `.debug_pubnames`
+//! section.
+//!
+//! * [`DebugPubTypes`](./struct.DebugPubTypes.html): The `.debug_pubtypes`
+//! section.
+//!
+//! * [`DebugRanges`](./struct.DebugRanges.html): The `.debug_ranges` section.
+//!
+//! * [`DebugRngLists`](./struct.DebugRngLists.html): The `.debug_rnglists` section.
+//!
+//! * [`DebugStr`](./struct.DebugStr.html): The `.debug_str` section.
+//!
+//! * [`DebugStrOffsets`](./struct.DebugStrOffsets.html): The `.debug_str_offsets` section.
+//!
+//! * [`DebugTypes`](./struct.DebugTypes.html): The `.debug_types` section.
+//!
+//! * [`DebugCuIndex`](./struct.DebugCuIndex.html): The `.debug_cu_index` section.
+//!
+//! * [`DebugTuIndex`](./struct.DebugTuIndex.html): The `.debug_tu_index` section.
+//!
+//! * [`EhFrame`](./struct.EhFrame.html): The `.eh_frame` section.
+//!
+//! * [`EhFrameHdr`](./struct.EhFrameHdr.html): The `.eh_frame_hdr` section.
+//!
+//! * Each section type exposes methods for accessing the debugging data encoded
+//! in that section. For example, the [`DebugInfo`](./struct.DebugInfo.html)
+//! struct has the [`units`](./struct.DebugInfo.html#method.units) method for
+//! iterating over the compilation units defined within it.
+//!
+//! * Offsets into a section are strongly typed: an offset into `.debug_info` is
+//! the [`DebugInfoOffset`](./struct.DebugInfoOffset.html) type. It cannot be
+//! used to index into the [`DebugLine`](./struct.DebugLine.html) type because
+//! `DebugLine` represents the `.debug_line` section. There are similar types
+//! for offsets relative to a compilation unit rather than a section.
+//!
+//! ## Using with `FallibleIterator`
+//!
+//! The standard library's `Iterator` trait and related APIs do not play well
+//! with iterators where the `next` operation is fallible. One can make the
+//! `Iterator`'s associated `Item` type be a `Result<T, E>`, however the
+//! provided methods cannot gracefully handle the case when an `Err` is
+//! returned.
+//!
+//! This situation led to the
+//! [`fallible-iterator`](https://crates.io/crates/fallible-iterator) crate's
+//! existence. You can read more of the rationale for its existence in its
+//! docs. The crate provides the helpers you have come to expect (eg `map`,
+//! `filter`, etc) for iterators that can fail.
+//!
+//! `gimli`'s many lazy parsing iterators are a perfect match for the
+//! `fallible-iterator` crate's `FallibleIterator` trait because parsing is not
+//! done eagerly. Parse errors later in the input might only be discovered after
+//! having iterated through many items.
+//!
+//! To use `gimli` iterators with `FallibleIterator`, import the crate and trait
+//! into your code:
+//!
+//! ```
+//! # #[cfg(feature = "fallible-iterator")]
+//! # fn foo() {
+//! // Use the `FallibleIterator` trait so its methods are in scope!
+//! use fallible_iterator::FallibleIterator;
+//! use gimli::{DebugAranges, EndianSlice, LittleEndian};
+//!
+//! fn find_sum_of_address_range_lengths(aranges: DebugAranges<EndianSlice<LittleEndian>>)
+//! -> gimli::Result<u64>
+//! {
+//! // `DebugAranges::headers` returns a `FallibleIterator`!
+//! aranges.headers()
+//! // `flat_map` is provided by `FallibleIterator`!
+//! .flat_map(|header| Ok(header.entries()))
+//! // `map` is provided by `FallibleIterator`!
+//! .map(|arange| Ok(arange.length()))
+//! // `fold` is provided by `FallibleIterator`!
+//! .fold(0, |sum, len| Ok(sum + len))
+//! }
+//! # }
+//! # fn main() {}
+//! ```

+/// # Usage
+/// A DWARF expression may require additional data to produce a final result,
+/// such as the value of a register or a memory location. Once initial setup
+/// is complete (i.e. `set_initial_value()`, `set_object_address()`) the
+/// consumer calls the `evaluate()` method. That returns an `EvaluationResult`,
+/// which is either `EvaluationResult::Complete` or a value indicating what
+/// data is needed to resume the `Evaluation`. The consumer is responsible for
+/// producing that data and resuming the computation with the correct method,
+/// as documented for `EvaluationResult`. Only once an `EvaluationResult::Complete`
+/// is returned can the consumer call `result()`.
+///
+/// This design allows the consumer of `Evaluation` to decide how and when to
+/// produce the required data and resume the computation. The `Evaluation` can
+/// be driven synchronously (as shown below) or by some asynchronous mechanism
+/// such as futures.

+/// ## Choosing a `Reader` Implementation
+///
+/// `gimli` comes with a few different `Reader` implementations and lets you

+/// view into the raw bytes that make up some DWARF, but this view might borrow
+/// the underlying data or use reference counting ownership, and it might be
+/// thread safe or not.
+///
+/// | Implementation | Ownership | Thread Safe | Notes |
+/// |:------------------|:------------------|:------------|:------|
+/// | [`EndianSlice`](./struct.EndianSlice.html) | Borrowed | Yes | Fastest, but requires that all of your code work with borrows. |
+/// | [`EndianRcSlice`](./struct.EndianRcSlice.html) | Reference counted | No | Shared ownership via reference counting, which alleviates the borrow restrictions of `EndianSlice` but imposes reference counting increments and decrements. Cannot be sent across threads, because the reference count is not atomic. |
+/// | [`EndianArcSlice`](./struct.EndianArcSlice.html) | Reference counted | Yes | The same as `EndianRcSlice`, but uses atomic reference counting, and therefore reference counting operations are slower but `EndianArcSlice`s may be sent across threads. |
+/// | [`EndianReader<T>`](./struct.EndianReader.html) | Same as `T` | Same as `T` | Escape hatch for easily defining your own type of `Reader`. |

+/// A raw reader of the data that defines the Debugging Information Entries.

+/// `EntriesRaw` provides primitives to read the components of Debugging Information

+/// followed by a number of attributes (read with `read_attribute`).
+/// The user must provide the control flow to read these correctly.
+/// In particular, all attributes must always be read before reading another

+//! Write DWARF debugging information.
+//!
+//! ## API Structure
+//!
+//! This module works by building up a representation of the debugging information
+//! in memory, and then writing it all at once. It supports two major use cases:
+//!
+//! * Use the [`DwarfUnit`](./struct.DwarfUnit.html) type when writing DWARF
+//! for a single compilation unit.
+//!
+//! * Use the [`Dwarf`](./struct.Dwarf.html) type when writing DWARF for multiple
+//! compilation units.
+//!
+//! The module also supports reading in DWARF debugging information and writing it out
+//! again, possibly after modifying it. Create a [`read::Dwarf`](../read/struct.Dwarf.html)
+//! instance, and then use [`Dwarf::from`](./struct.Dwarf.html#method.from) to convert
+//! it to a writable instance.
+//!
+//! ## Example Usage
+//!
+//! Write a compilation unit containing only the top level DIE.
+//!
+//! ```rust
+//! use gimli::write::{
+//! Address, AttributeValue, DwarfUnit, EndianVec, Error, Range, RangeList, Sections,
+//! };
+//!
+//! fn example() -> Result<(), Error> {
+//! // Choose the encoding parameters.
+//! let encoding = gimli::Encoding {
+//! format: gimli::Format::Dwarf32,
+//! version: 5,
+//! address_size: 8,
+//! };
+//! // Create a container for a single compilation unit.
+//! let mut dwarf = DwarfUnit::new(encoding);
+//! // Set a range attribute on the root DIE.
+//! let range_list = RangeList(vec![Range::StartLength {
+//! begin: Address::Constant(0x100),
+//! length: 42,
+//! }]);
+//! let range_list_id = dwarf.unit.ranges.add(range_list);
+//! let root = dwarf.unit.root();
+//! dwarf.unit.get_mut(root).set(
+//! gimli::DW_AT_ranges,
+//! AttributeValue::RangeListRef(range_list_id),
+//! );
+//! // Create a `Vec` for each DWARF section.
+//! let mut sections = Sections::new(EndianVec::new(gimli::LittleEndian));
+//! // Finally, write the DWARF data to the sections.
+//! dwarf.write(&mut sections)?;
+//! sections.for_each(|id, data| {
+//! // Here you can add the data to the output object file.
+//! Ok(())
+//! })
+//! }
+//! # fn main() {
+//! # example().unwrap();
+//! # }

-Language Server Protocol types for Rust.

-This library uses the URL crate for parsing URIs. Note that there is
-some confusion on the meaning of URLs vs URIs:
-<http://stackoverflow.com/a/28865728/393898>. According to that
-information, on the classical sense of "URLs", "URLs" are a subset of
-URIs, But on the modern/new meaning of URLs, they are the same as
-URIs. The important take-away aspect is that the URL crate should be
-able to parse any URI, such as `urn:isbn:0451450523`.

+Language Server Protocol types for Rust.

+Based on: <https://microsoft.github.io/language-server-protocol/specification>
+
+This library uses the URL crate for parsing URIs. Note that there is
+some confusion on the meaning of URLs vs URIs:
+<http://stackoverflow.com/a/28865728/393898>. According to that
+information, on the classical sense of "URLs", "URLs" are a subset of
+URIs, But on the modern/new meaning of URLs, they are the same as
+URIs. The important take-away aspect is that the URL crate should be
+able to parse any URI, such as `urn:isbn:0451450523`.

+# miniz_oxide
+
+A fully safe, pure rust replacement for the [miniz](https://github.com/richgel999/miniz) DEFLATE/zlib encoder/decoder.
+The main intention of this crate is to be used as a back-end for the [flate2](https://github.com/alexcrichton/flate2-rs), but it can also be used on it's own. Using flate2 with the ```rust_backend``` feature provides an easy to use streaming API for miniz_oxide.
+
+The library is fully [no_std](https://docs.rust-embedded.org/book/intro/no-std.html), though it requires the use of the `alloc` and `collection` crates as it allocates memory.
+
+miniz_oxide 0.5.x Requires at least rust 1.40.0 0.3.x requires at least rust 0.36.0.
+
+miniz_oxide features no use of unsafe code.
+
+miniz_oxide can optionally be made to use a simd-accelerated version of adler32 via the [simd-adler32](https://crates.io/crates/simd-adler32) crate by enabling the 'simd' feature. This is not enabled by default as due to the use of simd intrinsics, the simd-adler32 has to use unsafe. The default setup uses the [adler](https://crates.io/crates/adler) crate which features no unsafe code.
+
+## Usage
+Simple compression/decompression:
+```rust
+
+use miniz_oxide::deflate::compress_to_vec;
+use miniz_oxide::inflate::decompress_to_vec;
+
+fn roundtrip(data: &[u8]) {
+ // Compress the input
+ let compressed = compress_to_vec(data, 6);
+ // Decompress the compressed input
+ let decompressed = decompress_to_vec(compressed.as_slice()).expect("Failed to decompress!");
+ // Check roundtrip succeeded
+ assert_eq!(data, decompressed);
+}
+
+fn main() {
+ roundtrip("Hello, world!".as_bytes());
+}
+
+```
+These simple functions will do everything in one go and are thus not recommended for use cases where the input size may be large or unknown, for that use case consider using miniz_oxide via flate2 or the low-level streaming functions instead.

+/// Main decompression function. Keeps decompressing data from `in_buf` until the `in_buf` is
+/// empty, `out` is full, the end of the deflate stream is hit, or there is an error in the
+/// deflate stream.
+///
+/// # Arguments
+///
+/// `r` is a [`DecompressorOxide`] struct with the state of this stream.
+///
+/// `in_buf` is a reference to the compressed data that is to be decompressed. The decompressor will
+/// start at the first byte of this buffer.
+///
+/// `out` is a reference to the buffer that will store the decompressed data, and that
+/// stores previously decompressed data if any.
+///
+/// * The offset given by `out_pos` indicates where in the output buffer slice writing should start.
+/// * If [`TINFL_FLAG_USING_NON_WRAPPING_OUTPUT_BUF`] is not set, the output buffer is used in a
+/// wrapping manner, and it's size is required to be a power of 2.
+/// * The decompression function normally needs access to 32KiB of the previously decompressed data
+///(or to the beginning of the decompressed data if less than 32KiB has been decompressed.)
+/// - If this data is not available, decompression may fail.
+/// - Some deflate compressors allow specifying a window size which limits match distances to
+/// less than this, or alternatively an RLE mode where matches will only refer to the previous byte
+/// and thus allows a smaller output buffer. The window size can be specified in the zlib
+/// header structure, however, the header data should not be relied on to be correct.
+///
+/// `flags` indicates settings and status to the decompression function.
+/// * The [`TINFL_FLAG_HAS_MORE_INPUT`] has to be specified if more compressed data is to be provided
+/// in a subsequent call to this function.
+/// * See the the [`inflate_flags`] module for details on other flags.
+///
+/// # Returns
+///
+/// Returns a tuple containing the status of the compressor, the number of input bytes read, and the
+/// number of bytes output to `out`.
+///
+/// This function shouldn't panic pending any bugs.

A fully safe, pure rust replacement for the [miniz](https://github.com/richgel999/miniz) DEFLATE/zlib encoder/decoder.
The main intention of this crate is to be used as a back-end for the [flate2](https://github.com/alexcrichton/flate2-rs), but it can also be used on it's own. Using flate2 with the ```rust_backend``` feature provides an easy to use streaming API for miniz_oxide.
-The library is fully [no_std](https://docs.rust-embedded.org/book/intro/no-std.html), though it requires the use of the `alloc` and `collection` crates as it allocates memory.
+The library is fully [no_std](https://docs.rust-embedded.org/book/intro/no-std.html). By default, the `with-alloc` feature is enabled, which requires the use of the `alloc` and `collection` crates as it allocates memory.
-miniz_oxide 0.5.x Requires at least rust 1.40.0 0.3.x requires at least rust 0.36.0.
+The `std` feature additionally turns on things only available if `no_std` is not used. Currently this only means implementing [Error](https://doc.rust-lang.org/stable/std/error/trait.Error.html) for the `DecompressError` error struct returned by the simple decompression functions if enabled together with `with-alloc`.
+
+Using the library with `default-features = false` removes the dependency on `alloc`
+and `collection` crates, making it suitable for systems without an allocator.
+Running without allocation reduces crate functionality:
+
+- The `deflate` module is removed complete
+- Some `inflate` functions which return a `Vec` are removed
+
+miniz_oxide 0.5.x and 0.6.x Requires at least rust 1.40.0 0.3.x requires at least rust 0.36.0.

-For anything more complex than plain foreground colour changes, you need to construct `Style` values themselves, rather than beginning with a `Colour`.
+For anything more complex than plain foreground color changes, you need to construct `Style` values themselves, rather than beginning with a `Color`.
You can do this by chaining methods based on a new `Style`, created with `Style::new()`.
Each method creates a new style that has that specific property set.
For example:
```rust
-use ansi_term::Style;
+use nu_ansi_term::Style;
println!("How about some {} and {}?",
Style::new().bold().paint("bold"),
Style::new().underline().paint("underline"));
```
-For brevity, these methods have also been implemented for `Colour` values, so you can give your styles a foreground colour without having to begin with an empty `Style` value:

+In some cases, you may find it easier to change the foreground on an existing `Style` rather than starting from the appropriate `Color`.
You can do this using the `fg` method:
```rust
-use ansi_term::Style;

```
-You can turn a `Colour` into a `Style` with the `normal` method.
-This will produce the exact same `ANSIString` as if you just used the `paint` method on the `Colour` directly, but it’s useful in certain cases: for example, you may have a method that returns `Styles`, and need to represent both the “red bold” and “red, but not bold” styles with values of the same type. The `Style` struct also has a `Default` implementation if you want to have a style with *nothing* set.

## Combining successive coloured strings
-The benefit of writing ANSI escape codes to the terminal is that they *stack*: you do not need to end every coloured string with a reset code if the text that follows it is of a similar style.
+The benefit of writing ANSI escape codes to the terminal is that they _stack_: you do not need to end every coloured string with a reset code if the text that follows it is of a similar style.
For example, if you want to have some blue text followed by some blue bold text, it’s possible to send the ANSI code for blue, followed by the ANSI code for bold, and finishing with a reset code without having to have an extra one between the two strings.
This crate can optimise the ANSI codes that get printed in situations like this, making life easier for your terminal renderer.
-The `ANSIStrings` struct takes a slice of several `ANSIString` values, and will iterate over each of them, printing only the codes for the styles that need to be updated as part of its formatting routine.
+The `AnsiStrings` struct takes a slice of several `AnsiString` values, and will iterate over each of them, printing only the codes for the styles that need to be updated as part of its formatting routine.
The following code snippet uses this to enclose a binary number displayed in red bold text inside some red, but not bold, brackets:
```rust
-use ansi_term::Colour::Red;
-use ansi_term::{ANSIString, ANSIStrings};
+use nu_ansi_term::Color::Red;
+use nu_ansi_term::{AnsiString, AnsiStrings};
let some_value = format!("{:b}", 42);
-let strings: &[ANSIString<'static>] = &[
+let strings: &[AnsiString<'static>] = &[
Red.paint("["),
Red.bold().paint(some_value),
Red.paint("]"),
];
-println!("Value: {}", ANSIStrings(strings));
+println!("Value: {}", AnsiStrings(strings));
```
There are several things to note here.
-Firstly, the `paint` method can take *either* an owned `String` or a borrowed `&str`.
-Internally, an `ANSIString` holds a copy-on-write (`Cow`) string value to deal with both owned and borrowed strings at the same time.

+Internally, an `AnsiString` holds a copy-on-write (`Cow`) string value to deal with both owned and borrowed strings at the same time.
This is used here to display a `String`, the result of the `format!` call, using the same mechanism as some statically-available `&str` slices.
-Secondly, that the `ANSIStrings` value works in the same way as its singular counterpart, with a `Display` implementation that only performs the formatting when required.

## Byte strings
This library also supports formatting `[u8]` byte strings; this supports applications working with text in an unknown encoding.
-`Style` and `Colour` support painting `[u8]` values, resulting in an `ANSIByteString`.
+`Style` and `Color` support painting `[u8]` values, resulting in an `AnsiByteString`.
This type does not implement `Display`, as it may not contain UTF-8, but it does provide a method `write_to` to write the result to any value that implements `Write`:
```rust
-use ansi_term::Colour::Green;
+use nu_ansi_term::Color::Green;
Green.paint("user data".as_bytes()).write_to(&mut std::io::stdout()).unwrap();
```
-Similarly, the type `ANSIByteStrings` supports writing a list of `ANSIByteString` values with minimal escape sequences:

+
+Provides a macro to simplify operator overloading. See the [documentation](https://docs.rs/overload/) for details and supported operators.
+
+## Example
+
+```rust
+extern crate overload;
+use overload::overload;
+use std::ops; // <- don't forget this or you'll get nasty errors
+
+#[derive(PartialEq, Debug)]
+struct Val {
+ v: i32
+}
+
+overload!((a: ?Val) + (b: ?Val) -> Val { Val { v: a.v + b.v } });
+```
+
+The macro call in the snippet above generates the following code:
+
+```rust
+impl ops::Add<Val> for Val {
+ type Output = Val;
+ fn add(self, b: Val) -> Self::Output {
+ let a = self;
+ Val { v: a.v + b.v }
+ }
+}
+impl ops::Add<&Val> for Val {
+ type Output = Val;
+ fn add(self, b: &Val) -> Self::Output {
+ let a = self;
+ Val { v: a.v + b.v }
+ }
+}
+impl ops::Add<Val> for &Val {
+ type Output = Val;
+ fn add(self, b: Val) -> Self::Output {
+ let a = self;
+ Val { v: a.v + b.v }

+//! Provides a macro to simplify operator overloading.
+//!
+//! To use, include the following:
+//! ```
+//! extern crate overload;
+//! use overload::overload;
+//! use std::ops; // <- don't forget this or you'll get nasty errors
+//! ```
+//!
+//! # Introduction
+//!
+//! Suppose we have the following `struct` definition:
+//! ```
+//! #[derive(PartialEq, Debug)]
+//! struct Val {
+//! v: i32
+//! }
+//! ```
+//! We can overload the addition of `Val`s like so:
+//! ```
+//! # extern crate overload;
+//! # use overload::overload;
+//! # use std::ops;
+//! # #[derive(PartialEq, Debug)]
+//! # struct Val {
+//! # v: i32
+//! # }
+//! overload!((a: Val) + (b: Val) -> Val { Val { v: a.v + b.v } });
+//! ```
+//! The macro call above generates the following code:
+//! ```ignore
+//! impl ops::Add<Val> for Val {
+//! type Output = Val;
+//! fn add(self, b: Val) -> Self::Output {
+//! let a = self;
+//! Val { v: a.v + b.v }
+//! }
+//! }
+//! ```
+//! We are now able to add `Val`s:
+//! ```
+//! # extern crate overload;
+//! # use overload::overload;
+//! # use std::ops;
+//! # #[derive(PartialEq, Debug)]
+//! # struct Val {
+//! # v: i32
+//! # }
+//! # overload!((a: Val) + (b: Val) -> Val { Val { v: a.v + b.v } });
+//! assert_eq!(Val{v:3} + Val{v:5}, Val{v:8});
+//! ```
+//!
+//! # Owned and borrowed types
+//!
+//! If we also wanted to overload addition for the borrowed type `&Val` we could write:
+//! ```
+//! # extern crate overload;
+//! # use overload::overload;
+//! # use std::ops;
+//! # #[derive(PartialEq, Debug)]
+//! # struct Val {
+//! # v: i32
+//! # }
+//! overload!((a: &Val) + (b: &Val) -> Val { Val { v: a.v + b.v } });
+//! ```
+//! We might also want to overload addition between the owned and borrowed types:
+//! ```
+//! # extern crate overload;
+//! # use overload::overload;
+//! # use std::ops;
+//! # #[derive(PartialEq, Debug)]
+//! # struct Val {
+//! # v: i32
+//! # }
+//! overload!((a: Val) + (b: &Val) -> Val { Val { v: a.v + b.v } });
+//! overload!((a: &Val) + (b: Val) -> Val { Val { v: a.v + b.v } });
+//! ```
+//! Let's see how we can write these combinations more concisely.
+//!
+//! We can include a `?` in front of a type to indicate that it should stand in for both the owned and borrowed type.
+//!
+//! To overload addition for all four combinations between `Val` and `&Val` we can therefore simply include a `?` in front of both types:
+//! ```
+//! # extern crate overload;
+//! # use overload::overload;
+//! # use std::ops;
+//! # #[derive(PartialEq, Debug)]
+//! # struct Val {
+//! # v: i32
+//! # }
+//! overload!((a: ?Val) + (b: ?Val) -> Val { Val { v: a.v + b.v } });
+//! ```
+//! The macro call above generates the following code:
+//! ```ignore
+//! impl ops::Add<Val> for Val {
+//! type Output = Val;
+//! fn add(self, b: Val) -> Self::Output {
+//! let a = self;
+//! Val { v: a.v + b.v }
+//! }
+//! }
+//!
+//! impl ops::Add<&Val> for Val {
+//! type Output = Val;
+//! fn add(self, b: &Val) -> Self::Output {
+//! let a = self;
+//! Val { v: a.v + b.v }
+//! }
+//! }
+//!
+//! impl ops::Add<Val> for &Val {
+//! type Output = Val;
+//! fn add(self, b: Val) -> Self::Output {
+//! let a = self;
+//! Val { v: a.v + b.v }
+//! }
+//! }
+//!
+//! impl ops::Add<&Val> for &Val {
+//! type Output = Val;
+//! fn add(self, b: &Val) -> Self::Output {
+//! let a = self;
+//! Val { v: a.v + b.v }
+//! }
+//! }
+//! ```
+//! We are now able to add `Val`s and `&Val`s in any combination:
+//! ```
+//! # extern crate overload;
+//! # use overload::overload;
+//! # use std::ops;
+//! # #[derive(PartialEq, Debug)]
+//! # struct Val {
+//! # v: i32
+//! # }
+//! # overload!((a: ?Val) + (b: ?Val) -> Val { Val { v: a.v + b.v } });
+//! assert_eq!(Val{v:3} + Val{v:5}, Val{v:8});
+//! assert_eq!(Val{v:3} + &Val{v:5}, Val{v:8});
+//! assert_eq!(&Val{v:3} + Val{v:5}, Val{v:8});
+//! assert_eq!(&Val{v:3} + &Val{v:5}, Val{v:8});
+//! ```
+//!
+//! # Binary operators
+//!
+//! The general syntax to overload a binary operator between types `<a_type>` and `<b_type>` is:
+//! ```ignore
+//! overload!((<a_ident>: <a_type>) <op> (<b_ident>: <b_type>) -> <out_type> { /*body*/ });
+//! ```
+//! Inside the body you can use `<a_ident>` and `<b_ident>` freely to perform any computation.
+//!
+//! The last line of the body needs to be an expression (i.e. no `;` at the end of the line) of type `<out_type>`.
+//!
+//! | Operator | Example | Trait |
+//! |----------|-----------------------------------------------------------------|--------|
+//! | + | `overload!((a: A) + (b: B) -> C { /*...*/ );` | Add |
+//! | - | `overload!((a: A) - (b: B) -> C { /*...*/ );` | Sub |
+//! | * | `overload!((a: A) * (b: B) -> C { /*...*/ );` | Mul |
+//! | / | `overload!((a: A) / (b: B) -> C { /*...*/ );` | Div |
+//! | % | `overload!((a: A) % (b: B) -> C { /*...*/ );` | Rem |
+//! | & | `overload!((a: A) & (b: B) -> C { /*...*/ );` | BitAnd |
+//! | \| | <code>overload!((a: A) &vert; (b: B) -> C { /\*...*\/ );</code> | BitOr |
+//! | ^ | `overload!((a: A) ^ (b: B) -> C { /*...*/ );` | BitXor |
+//! | << | `overload!((a: A) << (b: B) -> C { /*...*/ );` | Shl |
+//! | >> | `overload!((a: A) >> (b: B) -> C { /*...*/ );` | Shr |
+//!
+//! # Assignment operators
+//!
+//! The general syntax to overload an assignment operator between types `<a_type>` and `<b_type>` is:
+//! ```ignore
+//! overload!((<a_ident>: &mut <a_type>) <op> (<b_ident>: <b_type>) { /*body*/ });
+//! ```
+//! Inside the body you can use `<a_ident>` and `<b_ident>` freely to perform any computation and mutate `<a_ident>` as desired.
+//!
+//! | Operator | Example | Trait |
+//! |----------|------------------------------------------------------------------|--------------|
+//! | += | `overload!((a: &mut A) += (b: B) { /*...*/ );` | AddAssign |
+//! | -= | `overload!((a: &mut A) -= (b: B) { /*...*/ );` | SubAssign |
+//! | *= | `overload!((a: &mut A) *= (b: B) { /*...*/ );` | MulAssign |
+//! | /= | `overload!((a: &mut A) /= (b: B) { /*...*/ );` | DivAssign |
+//! | %= | `overload!((a: &mut A) %= (b: B) { /*...*/ );` | RemAssign |
+//! | &= | `overload!((a: &mut A) &= (b: B) { /*...*/ );` | BitAndAssign |
+//! | \|= | <code>overload!((a: &mut A) &vert;= (b: B) { /\*...*\/ );</code> | BitOrAssign |
+//! | ^= | `overload!((a: &mut A) ^= (b: B) { /*...*/ );` | BitXorAssign |
+//! | <<= | `overload!((a: &mut A) <<= (b: B) { /*...*/ );` | ShlAssign |
+//! | >>= | `overload!((a: &mut A) >>= (b: B) { /*...*/ );` | ShrAssign |
+//!
+//! # Unary operators
+//!
+//! The general syntax to overload a unary operator for type `<a_type>` is:
+//! ```ignore
+//! overload!(<op> (<a_ident>: <a_type>) -> <out_type> { /*body*/ });
+//! ```
+//! Inside the body you can use `<a_ident>` freely to perform any computation.
+//!
+//! The last line of the body needs to be an expression (i.e. no `;` at the end of the line) of type `<out_type>`.
+//!
+//! | Operator | Example | Trait |
+//! |----------|---------------------------------------------------------|-------|
+//! | - | `overload!(- (a: A) -> B { /*...*/ );` | Neg |
+//! | ! | `overload!(! (a: A) -> B { /*...*/ );` | Not |
+//!
+//! # Notes
+//!
+//! Remember that you can only overload operators between one or more types if at least one of the types is defined in the current crate.

+# Release rayon 1.6.1 (2022-12-09)
+
+- Simplified `par_bridge` to only pull one item at a time from the iterator,
+ without batching. Threads that are waiting for iterator items will now block
+ appropriately rather than spinning CPU. (Thanks @njaard!)
+- Added protection against recursion in `par_bridge`, so iterators that also
+ invoke rayon will not cause mutex recursion deadlocks.
+
+# Release rayon-core 1.10.1 (2022-11-18)
+
+- Fixed a race condition with threads going to sleep while a broadcast starts.
+
# Release rayon 1.6.0 / rayon-core 1.10.0 (2022-11-18)
- The minimum supported `rustc` is now 1.56.

-# RLS-data
-
-Data structures used by the RLS and the Rust compiler.
-
-These are used by the save-analysis functionality in the compiler
-(`rustc -Zsave-analysis`). In that use, the compiler translates info in its
-internal data structures to these data structures then serialises them as JSON.
-Clients (such as the RLS) can use this crate when deserialising.
-
-The data can also be passed directly from compiler to client if the compiler is
-used as a library.

+ // Our first line of defense is the borrow checker: we have a mutable borrow, so nothing

+ // state again before we release the borrow, everything should be A-OK! We do this cleanup
+ // in our Drop impl.
+ //
+ // Unfortunately, that's unsound, because mem::forget exists and The Leakpocalypse Is Real.

+ // leaks the Drain, we just leak everything the ThinVec contained out of spite! If they
+ // *don't* leak us then we can properly repair the len in our Drop impl. This is known
+ // as "leak amplification", and is the same approach std uses.
+ //
+ // But we can do slightly better than setting the len to 0! The drain breaks us up into

+ //
+ // ```text
+ //
+ // [A, B, C, D, E, F, G, H, _, _]
+ // ____ __________ ____ ____
+ // | | | |
+ // prefix drain tail spare-cap
+ // ```
+ //
+ // As the drain iterator is consumed from both ends (DoubleEnded!), we'll start to look
+ // like this:
+ //
+ // ```text
+ // [A, B, _, _, E, _, G, H, _, _]
+ // ____ __________ ____ ____
+ // | | | |
+ // prefix drain tail spare-cap
+ // ```
+ //
+ // Note that the prefix is always valid and untouched, as such we can set the len
+ // to the prefix when doing leak-amplification. As a bonus, we can use this value
+ // to remember where the drain range starts. At the end we'll look like this
+ // (we exhaust ourselves in our Drop impl):
+ //
+ // ```text
+ // [A, B, _, _, _, _, G, H, _, _]
+ // _____ __________ _____ ____
+ // | | | |
+ // len drain tail spare-cap

+ // ___________ ________________

+# 0.3.16 (October 6, 2022)
+
+This release of `tracing-subscriber` fixes a regression introduced in
+[v0.3.15][subscriber-0.3.15] where `Option::None`'s `Layer` implementation would
+set the max level hint to `OFF`. In addition, it adds several new APIs,
+including the `Filter::event_enabled` method for filtering events based on
+fields values, and the ability to log internal errors that occur when writing a
+log line.
+
+This release also replaces the dependency on the unmaintained [`ansi-term`]
+crate with the [`nu-ansi-term`] crate, resolving an *informational* security
+advisory ([RUSTSEC-2021-0139]) for [`ansi-term`]'s maintainance status. This
+increases the minimum supported Rust version (MSRV) to Rust 1.50+, although the
+crate should still compile for the previous MSRV of Rust 1.49+ when the `ansi`
+feature is not enabled.
+
+### Fixed
+
+- **layer**: `Option::None`'s `Layer` impl always setting the `max_level_hint`
+ to `LevelFilter::OFF` ([#2321])
+- Compilation with `-Z minimal versions` ([#2246])
+- **env-filter**: Clarify that disabled level warnings are emitted by
+ `tracing-subscriber` ([#2285])
+
+### Added
+
+- **fmt**: Log internal errors to `stderr` if writing a log line fails ([#2102])
+- **fmt**: `FmtLayer::log_internal_errors` and
+ `FmtSubscriber::log_internal_errors` methods for configuring whether internal
+ writer errors are printed to `stderr` ([#2102])
+- **fmt**: `#[must_use]` attributes on builders to warn if a `Subscriber` is
+ configured but not set as the default subscriber ([#2239])
+- **filter**: `Filter::event_enabled` method for filtering an event based on its
+ fields ([#2245], [#2251])
+- **filter**: `Targets::default_level` accessor ([#2242])
+
+### Changed
+
+- **ansi**: Replaced dependency on unmaintained `ansi-term` crate with
+ `nu-ansi-term` (([#2287], fixes informational advisory [RUSTSEC-2021-0139])
+- `tracing-core`: updated to [0.1.30][core-0.1.30]
+- Minimum Supported Rust Version (MSRV) increased to Rust 1.50+ (when the
+ `ansi`) feature flag is enabled ([#2287])
+
+### Documented
+
+- **fmt**: Correct inaccuracies in `fmt::init` documentation ([#2224])
+- **filter**: Fix incorrect doc link in `filter::Not` combinator ([#2249])
+
+Thanks to new contributors @cgbur, @DesmondWillowbrook, @RalfJung, and
+@poliorcetics, as well as returning contributors @CAD97, @connec, @jswrenn,

+# 0.3.15 (Jul 20, 2022)
+
+This release fixes a bug where the `reload` layer would fail to pass through
+`max_level_hint` to the underlying layer, potentially breaking filtering.
+
+### Fixed
+
+- **reload**: pass through `max_level_hint` to the inner `Layer` ([#2204])
+
+Thanks to @guswynn for contributing to this release!
+
+[#2204]: https://github.com/tokio-rs/tracing/pull/2204
+
+# 0.3.14 (Jul 1, 2022)
+
+This release fixes multiple filtering bugs in the `Layer` implementations for
+`Option<impl Layer>` and `Vec<impl Layer>`.
+
+### Fixed
+
+- **layer**: `Layer::event_enabled` implementation for `Option<impl Layer<S>>`
+ returning `false` when the `Option` is `None`, disabling all events globally
+ ([#2193])
+- **layer**: `Layer::max_level_hint` implementation for `Option<impl Layer<S>>`
+ incorrectly disabling max level filtering when the option is `None` ([#2195])
+- **layer**: `Layer::max_level_hint` implementation for `Vec<impl Layer<S>>`
+ returning `LevelFilter::ERROR` rather than `LevelFilter::OFF` when the `Vec`
+ is empty ([#2195])
+
+Thanks to @CAD97 and @guswynn for contributing to this release!

+# 0.3.13 (Jun 30, 2022) (YANKED)
+
+This release of `tracing-subscriber` fixes a compilation failure due to an
+incorrect `tracing-core` dependency that was introduced in v0.3.12.
+
+### Changed
+
+- **tracing_core**: Updated minimum dependency version to 0.1.28 ([#2190])
+
+[#2190]: https://github.com/tokio-rs/tracing/pull/2190
+
+# 0.3.12 (Jun 29, 2022) (YANKED)
+
+This release of `tracing-subscriber` adds a new `Layer::event_enabled` method,
+which allows `Layer`s to filter events *after* their field values are recorded;
+a `Filter` implementation for `reload::Layer`, to make using `reload` with
+per-layer filtering more ergonomic, and additional inherent method downcasting
+APIs for the `Layered` type. In addition, it includes dependency updates, and
+minor fixes for documentation and feature flagging.
+
+### Added
+
+- **layer**: `Layer::event_enabled` method, which can be implemented to filter
+ events based on their field values ([#2008])
+- **reload**: `Filter` implementation for `reload::Layer` ([#2159])
+- **layer**: `Layered::downcast_ref` and `Layered::is` inherent methods
+ ([#2160])
+
+### Changed
+
+- **parking_lot**: Updated dependency on `parking_lot` to 0.13.0 ([#2143])
+- Replaced `lazy_static` dependency with `once_cell` ([#2147])
+
+### Fixed
+
+- Don't enable `tracing-core` features by default ([#2107])
+- Several documentation link and typo fixes ([#2064], [#2068], #[2077], [#2161],
+ [#1088])
+
+Thanks to @ben0x539, @jamesmunns, @georgemp, @james7132, @jswrenn, @CAD97, and

+# 0.3.11 (Apr 9, 2022)
+
+This is a bugfix release for the `Filter` implementation for `EnvFilter` added
+in [v0.3.10].
+
+### Fixed
+
+- **env-filter**: Added missing `Filter::on_record` callback to `EnvFilter`'s
+ `Filter` impl ([#2058])
+- **env-filter**: Fixed method resolution issues when calling `EnvFilter`
+ methods with both the `Filter` and `Layer` traits in scope ([#2057])

+
+# 0.3.10 (Apr 1, 2022)
+
+This release adds several new features, including a `Filter` implementation and
+new builder API for `EnvFilter`, support for using a `Vec<L> where L: Layer` as
+a `Layer`, and a number of smaller API improvements to make working with dynamic
+and reloadable layers easier.
+
+### Added
+
+- **registry**: Implement `Filter` for `EnvFilter`, allowing it to be used with
+ per-layer filtering ([#1983])
+- **registry**: `Filter::on_new_span`, `Filter::on_enter`,
+ `Filter::on_exit`, `Filter::on_close` and `Filter::on_record` callbacks to
+ allow `Filter`s to track span states internally ([#1973], [#2017], [#2031])
+- **registry**: `Filtered::filter` and `Filtered::filter_mut` accessors
+ ([#1959])
+- **registry**: `Filtered::inner` and `Filtered::inner_mut` accessors to borrow
+ the wrapped `Layer` ([#2034])
+- **layer**: Implement `Layer` for `Vec<L: Layer>`, to allow composing together
+ a dynamically sized list of `Layer`s ([#2027])
+- **layer**: `Layer::boxed` method to make type-erasing `Layer`s easier
+ ([#2026])
+- **fmt**: `fmt::Layer::writer` and `fmt::Layer::writer_mut` accessors ([#2034])
+- **fmt**: `fmt::Layer::set_ansi` method to allow changing the ANSI formatting
+ configuration at runtime ([#2034])
+- **env-filter**: `EnvFilter::builder` to configure a new `EnvFilter` prior to
+ parsing it ([#2035])
+- Several documentation fixes and improvements ([#1972], [#1971], [#2023],
+ [#2023])
+
+### Fixed
+
+- **fmt**: `fmt::Layer`'s auto traits no longer depend on the `Subscriber` type
+ parameter's auto traits ([#2025])
+- **env-filter**: Fixed missing help text when the `ansi` feature is disabled
+ ([#2029])
+

+# 0.3.8 (Feb 4, 2022)
+
+This release adds *experimental* support for recording structured field
+values using the [`valuable`] crate to the `format::Json` formatter. In
+particular, user-defined types which are recorded using their
+[`valuable::Valuable`] implementations will be serialized as JSON objects,
+rather than using their `fmt::Debug` representation. See [this blog post][post]
+for details on `valuable`.
+
+Note that `valuable` support currently requires `--cfg tracing_unstable`. See
+the documentation for details.
+
+Additionally, this release includes a number of other smaller API improvements.
+
+### Added
+
+- **json**: Experimental support for recording [`valuable`] values as structured
+ JSON ([#1862], [#1901])
+- **filter**: `Targets::would_enable` method for testing if a `Targets` filter
+ would enable a given target ([#1903])
+- **fmt**: `map_event_format`, `map_fmt_fields`, and `map_writer` methods to
+ `fmt::Layer` and `fmt::SubscriberBuilder` ([#1871])
+
+### Changed
+
+- `tracing-core`: updated to [0.1.22][core-0.1.22]
+
+### Fixed
+
+- Set `smallvec` minimal version to 1.2.0, to fix compilation errors with `-Z
+ minimal-versions` ([#1890])
+- Minor documentation fixes ([#1902], [#1893])
+
+Thanks to @guswynn, @glts, and @lilyball for contributing to this release!

+# 0.3.7 (Jan 25, 2022)
+
+This release adds combinators for combining filters.
+
+Additionally, this release also updates the `thread-local` crate to v1.1.4,
+fixing warnings for the security advisory [RUSTSEC-2022-0006]. Note that
+previous versions of `tracing-subscriber` did not use any of the `thread-local`
+crate's APIs effected by the vulnerability. However, updating the version fixes
+warnings emitted by `cargo audit` and similar tools.

+ configuration methods to `fmt::Format`, `fmt::SubscriberBuilder`, and
+ `fmt::Layer` ([#1773])
+
+### Fixed
+
+- **fmt**: Removed incorrect leading comma from span fields with the `Pretty`
+ formatter ([#1833])
+
+### Deprecated

+using local timestamps with the `time` crate.
+
+### Added
+
+- **fmt**: Added `OffsetLocalTime` formatter to `fmt::time` for formatting local
+ timestamps with a fixed offset ([#1772])
+
+### Fixed
+
+- **fmt**: Added a `Targets` filter to `fmt::init()` and `fmt::try_init()` when
+ the "env-filter" feature is disabled, so that `RUST_LOG` is still honored
+ ([#1781])

//! Formatters for logging `tracing` events.
+//!
+//! This module provides several formatter implementations, as well as utilities
+//! for implementing custom formatters.
+//!
+//! # Formatters
+//! This module provides a number of formatter implementations:
+//!
+//! * [`Full`]: The default formatter. This emits human-readable,
+//! single-line logs for each event that occurs, with the current span context
+//! displayed before the formatted representation of the event. See
+//! [here](Full#example-output) for sample output.
+//!
+//! * [`Compact`]: A variant of the default formatter, optimized for
+//! short line lengths. Fields from the current span context are appended to
+//! the fields of the formatted event, and span names are not shown; the
+//! verbosity level is abbreviated to a single character. See
+//! [here](Compact#example-output) for sample output.
+//!
+//! * [`Pretty`]: Emits excessively pretty, multi-line logs, optimized
+//! for human readability. This is primarily intended to be used in local
+//! development and debugging, or for command-line applications, where
+//! automated analysis and compact storage of logs is less of a priority than
+//! readability and visual appeal. See [here](Pretty#example-output)
+//! for sample output.
+//!
+//! * [`Json`]: Outputs newline-delimited JSON logs. This is intended
+//! for production use with systems where structured logs are consumed as JSON
+//! by analysis and viewing tools. The JSON output is not optimized for human
+//! readability. See [here](Json#example-output) for sample output.

+//! ## Runtime Configuration With `Layer`s
+//!
+//! In some cases, a particular [`Layer`] may be enabled or disabled based on
+//! runtime configuration. This can introduce challenges, because the type of a
+//! layered [`Subscriber`] depends on which layers are added to it: if an `if`
+//! or `match` expression adds some [`Layer`] implementation in one branch,
+//! and other layers in another, the [`Subscriber`] values returned by those
+//! branches will have different types. For example, the following _will not_
+//! work:
+//!
+//! ```compile_fail
+//! # fn docs() -> Result<(), Box<dyn std::error::Error + 'static>> {
+//! # struct Config {
+//! # is_prod: bool,
+//! # path: &'static str,
+//! # }
+//! # let cfg = Config { is_prod: false, path: "debug.log" };
+//! use std::fs::File;
+//! use tracing_subscriber::{Registry, prelude::*};
+//!
+//! let stdout_log = tracing_subscriber::fmt::layer().pretty();
+//! let subscriber = Registry::default().with(stdout_log);
+//!
+//! // The compile error will occur here because the if and else
+//! // branches have different (and therefore incompatible) types.
+//! let subscriber = if cfg.is_prod {
+//! let file = File::create(cfg.path)?;
+//! let layer = tracing_subscriber::fmt::layer()
+//! .json()
+//! .with_writer(Arc::new(file));
+//! layer.with(subscriber)
+//! } else {
+//! layer
+//! };
+//!
+//! tracing::subscriber::set_global_default(subscriber)
+//! .expect("Unable to set global subscriber");
+//! # Ok(()) }
+//! ```
+//!
+//! However, a [`Layer`] wrapped in an [`Option`] [also implements the `Layer`
+//! trait][option-impl]. This allows individual layers to be enabled or disabled at
+//! runtime while always producing a [`Subscriber`] of the same type. For
+//! example:
+//!
+//! ```
+//! # fn docs() -> Result<(), Box<dyn std::error::Error + 'static>> {
+//! # struct Config {
+//! # is_prod: bool,
+//! # path: &'static str,
+//! # }
+//! # let cfg = Config { is_prod: false, path: "debug.log" };
+//! use std::fs::File;
+//! use tracing_subscriber::{Registry, prelude::*};
+//!
+//! let stdout_log = tracing_subscriber::fmt::layer().pretty();
+//! let subscriber = Registry::default().with(stdout_log);
+//!
+//! // if `cfg.is_prod` is true, also log JSON-formatted logs to a file.
+//! let json_log = if cfg.is_prod {
+//! let file = File::create(cfg.path)?;
+//! let json_log = tracing_subscriber::fmt::layer()
+//! .json()
+//! .with_writer(file);
+//! Some(json_log)
+//! } else {
+//! None
+//! };
+//!
+//! // If `cfg.is_prod` is false, then `json` will be `None`, and this layer
+//! // will do nothing. However, the subscriber will still have the same type
+//! // regardless of whether the `Option`'s value is `None` or `Some`.
+//! let subscriber = subscriber.with(json_log);
+//!
+//! tracing::subscriber::set_global_default(subscriber)
+//! .expect("Unable to set global subscriber");
+//! # Ok(()) }
+//! ```
+//!
+//! If a [`Layer`] may be one of several different types, note that [`Box<dyn
+//! Layer<S> + Send + Sync>` implements `Layer`][box-impl].
+//! This may be used to erase the type of a [`Layer`].
+//!
+//! For example, a function that configures a [`Layer`] to log to one of
+//! several outputs might return a `Box<dyn Layer<S> + Send + Sync + 'static>`:
+//! ```
+//! use tracing_subscriber::{
+//! Layer,
+//! registry::LookupSpan,
+//! prelude::*,
+//! };
+//! use std::{path::PathBuf, fs::File, io};
+//!
+//! /// Configures whether logs are emitted to a file, to stdout, or to stderr.
+//! pub enum LogConfig {
+//! File(PathBuf),
+//! Stdout,
+//! Stderr,
+//! }
+//!
+//! impl LogConfig {
+//! pub fn layer<S>(self) -> Box<dyn Layer<S> + Send + Sync + 'static>

+//!
+//! // Configure the writer based on the desired log target:
+//! match self {
+//! LogConfig::File(path) => {
+//! let file = File::create(path).expect("failed to create log file");
+//! Box::new(fmt.with_writer(file))
+//! },
+//! LogConfig::Stdout => Box::new(fmt.with_writer(io::stdout)),
+//! LogConfig::Stderr => Box::new(fmt.with_writer(io::stderr)),
+//! }
+//! }
+//! }
+//!
+//! let config = LogConfig::Stdout;
+//! tracing_subscriber::registry()
+//! .with(config.layer())
+//! .init();
+//! ```
+//!
+//! The [`Layer::boxed`] method is provided to make boxing a `Layer`
+//! more convenient, but [`Box::new`] may be used as well.
+//!
+//! When the number of `Layer`s varies at runtime, note that a
+//! [`Vec<L> where L: Layer` also implements `Layer`][vec-impl]. This
+//! can be used to add a variable number of `Layer`s to a `Subscriber`:
+//!
+//! ```
+//! use tracing_subscriber::{Layer, prelude::*};
+//! struct MyLayer {
+//! // ...
+//! }
+//! # impl MyLayer { fn new() -> Self { Self {} }}
+//!
+//! impl<S: tracing_core::Subscriber> Layer<S> for MyLayer {
+//! // ...
+//! }
+//!
+//! /// Returns how many layers we need
+//! fn how_many_layers() -> usize {
+//! // ...
+//! # 3
+//! }
+//!
+//! // Create a variable-length `Vec` of layers
+//! let mut layers = Vec::new();
+//! for _ in 0..how_many_layers() {
+//! layers.push(MyLayer::new());
+//! }
+//!
+//! tracing_subscriber::registry()
+//! .with(layers)
+//! .init();
+//! ```
+//!
+//! If a variable number of `Layer` is needed and those `Layer`s have
+//! different types, a `Vec` of [boxed `Layer` trait objects][box-impl] may
+//! be used. For example:
+//!
+//! ```
+//! use tracing_subscriber::{filter::LevelFilter, Layer, prelude::*};

-//! ## Runtime Configuration With Layers
-//!
-//! In some cases, a particular [`Layer`] may be enabled or disabled based on
-//! runtime configuration. This can introduce challenges, because the type of a
-//! layered [`Subscriber`] depends on which layers are added to it: if an `if`
-//! or `match` expression adds some [`Layer`]s in one branch and other layers
-//! in another, the [`Subscriber`] values returned by those branches will have
-//! different types. For example, the following _will not_ work:
-//!
-//! ```compile_fail
-//! # fn docs() -> Result<(), Box<dyn std::error::Error + 'static>> {
-//! # struct Config {
-//! # is_prod: bool,
-//! # path: &'static str,
-//! # }
-//! # let cfg = Config { is_prod: false, path: "debug.log" };
-//! use std::{fs::File, sync::Arc};
-//! use tracing_subscriber::{Registry, prelude::*};
-//!
-//! let stdout_log = tracing_subscriber::fmt::layer().pretty();
-//! let subscriber = Registry::default().with(stdout_log);
-//!
-//! // The compile error will occur here because the if and else
-//! // branches have different (and therefore incompatible) types.
-//! let subscriber = if cfg.is_prod {
-//! let file = File::create(cfg.path)?;
-//! let layer = tracing_subscriber::fmt::layer()
-//! .json()
-//! .with_writer(Arc::new(file));
-//! subscriber.with(layer)
-//! } else {
-//! subscriber
-//! };
-//!
-//! tracing::subscriber::set_global_default(subscriber)
-//! .expect("Unable to set global subscriber");
-//! # Ok(()) }
-//! ```
-//!
-//! However, a [`Layer`] wrapped in an [`Option`] [also implements the `Layer`
-//! trait][option-impl]. This allows individual layers to be enabled or disabled at
-//! runtime while always producing a [`Subscriber`] of the same type. For
-//! example:
-//!
-//! ```
-//! # fn docs() -> Result<(), Box<dyn std::error::Error + 'static>> {
-//! # struct Config {
-//! # is_prod: bool,
-//! # path: &'static str,
-//! # }
-//! # let cfg = Config { is_prod: false, path: "debug.log" };
-//! use std::{fs::File, sync::Arc};
-//! use tracing_subscriber::{Registry, prelude::*};
-//!
-//! let stdout_log = tracing_subscriber::fmt::layer().pretty();
-//! let subscriber = Registry::default().with(stdout_log);
-//!
-//! // if `cfg.is_prod` is true, also log JSON-formatted logs to a file.
-//! let json_log = if cfg.is_prod {
-//! let file = File::create(cfg.path)?;
-//! let json_log = tracing_subscriber::fmt::layer()
-//! .json()
-//! .with_writer(Arc::new(file));
-//! Some(json_log)
-//! } else {
-//! None
-//! };
-//!
-//! // If `cfg.is_prod` is false, then `json` will be `None`, and this layer
-//! // will do nothing. However, the subscriber will still have the same type
-//! // regardless of whether the `Option`'s value is `None` or `Some`.
-//! let subscriber = subscriber.with(json_log);

+//! env variable when running `cargo` commands:
+//!
+//! ```shell
+//! RUSTFLAGS="--cfg tracing_unstable" cargo build

+//! Alternatively, the following can be added to the `.cargo/config` file in a

+//! Wrapper for a `Layer` to allow it to be dynamically reloaded.
+//!
+//! This module provides a [`Layer` type] implementing the [`Layer` trait] or [`Filter` trait]
+//! which wraps another type implementing the corresponding trait. This
+//! allows the wrapped type to be replaced with another
+//! instance of that type at runtime.
+//!
+//! This can be used in cases where a subset of `Layer` or `Filter` functionality
+//! should be dynamically reconfigured, such as when filtering directives may
+//! change at runtime. Note that this layer introduces a (relatively small)
+//! amount of overhead, and should thus only be used as needed.
+//!
+//! # Examples
+//!
+//! Reloading a [global filtering](crate::layer#global-filtering) layer:
+//!
+//! ```rust
+//! # use tracing::info;
+//! use tracing_subscriber::{filter, fmt, reload, prelude::*};
+//! let filter = filter::LevelFilter::WARN;
+//! let (filter, reload_handle) = reload::Layer::new(filter);
+//! tracing_subscriber::registry()
+//! .with(filter)
+//! .with(fmt::Layer::default())
+//! .init();
+//! #
+//! # // specifying the Registry type is required
+//! # let _: &reload::Handle<filter::LevelFilter, tracing_subscriber::Registry> = &reload_handle;
+//! #
+//! info!("This will be ignored");
+//! reload_handle.modify(|filter| *filter = filter::LevelFilter::INFO);
+//! info!("This will be logged");
+//! ```
+//!
+//! Reloading a [`Filtered`](crate::filter::Filtered) layer:
+//!
+//! ```rust
+//! # use tracing::info;
+//! use tracing_subscriber::{filter, fmt, reload, prelude::*};
+//! let filtered_layer = fmt::Layer::default().with_filter(filter::LevelFilter::WARN);
+//! let (filtered_layer, reload_handle) = reload::Layer::new(filtered_layer);
+//! #
+//! # // specifying the Registry type is required
+//! # let _: &reload::Handle<filter::Filtered<fmt::Layer<tracing_subscriber::Registry>,
+//! # filter::LevelFilter, tracing_subscriber::Registry>,tracing_subscriber::Registry>
+//! # = &reload_handle;
+//! #
+//! tracing_subscriber::registry()
+//! .with(filtered_layer)
+//! .init();
+//! info!("This will be ignored");
+//! reload_handle.modify(|layer| *layer.filter_mut() = filter::LevelFilter::INFO);
+//! info!("This will be logged");
+//! ```
+//!
+//! ## Note
+//!
+//! The [`Layer`] implementation is unable to implement downcasting functionality,
+//! so certain [`Layer`] will fail to downcast if wrapped in a `reload::Layer`.
+//!
+//! If you only want to be able to dynamically change the
+//! `Filter` on a layer, prefer wrapping that `Filter` in the `reload::Layer`.

-/// A type implementing `IsCovariant<'a>` is covariant with respect to lifetime `'a`.
-///
-/// Lifetime parameters that are safely cast in [`Yokeable`] are also valid for `IsCovariant`.
-///
-/// `IsCovariant` exists primarily to serve in trait bounds. The primary use case is to safely
-/// perform lifetime casting on trait objects (`dyn Trait`). This enables a type-erased [`Yoke`]
-/// consisting of only trait objects. See the examples.
-///
-/// `IsCovariant` is auto-implemented in [`#[derive(Yokeable)]`](macro@crate::Yokeable).
-///
-/// # Safety
-///
-/// This trait is safe to implement on types with a _covariant_ lifetime parameter. This will
-/// occur when the lifetime parameter is used within references, but not in the arguments of
-/// function pointers or in mutable positions (either in `&mut` or via interior mutability).
-///
-/// If a struct has multiple lifetime parameters, only the one used in `IsCovariant<'a>` needs to
-/// be covariant.
-///
-/// # Examples
-///
-/// Implementing on a simple struct with a single covariant lifetime:
-///
-/// ```
-/// # use yoke::*;
-/// struct MyStruct<'a>(&'a str);
-///
-/// // This is safe because 'a is covariant
-/// unsafe impl<'a> IsCovariant<'a> for MyStruct<'a> {}
-/// ```
-///
-/// By constraining the trait `ExampleTrait<'a>` on `IsCovariant<'a>`, we can safely implement
-/// [`Yokeable`] and [`ZeroFrom`] on its trait object:
-///
-/// ```
-/// # use yoke::*;
-/// # use zerofrom::*;
-/// # use core::mem;
-/// trait ExampleTrait<'a>: IsCovariant<'a> {
-/// fn get_message(&self) -> &'a str;
-/// }
-///
-/// // This wrapper is required because of the blanket Yokeable impl on &'static T
-/// pub struct ExampleTraitDynRef<'a>(pub &'a dyn ExampleTrait<'a>);
-///
-/// // The following impl is safe because the trait object requires IsCovariant.
-/// unsafe impl<'a> Yokeable<'a> for ExampleTraitDynRef<'static> {
-/// type Output = ExampleTraitDynRef<'a>;

+/// A way to be sure of this is as follows: imagine if `F` *did* borrow data of lifetime `'a` and stuff it in

+/// The only lifetime that satisfies that is `'static` (since at least one of the potential `'de`s is `'static`),
+/// and we're fine with that.
+///
+/// ## Implied bounds and variance
+///
+/// The `C::Target: 'static` bound is tricky, however. Let's imagine a situation where we *didn't* have that bound.
+///
+/// One thing to remember is that we are okay with the cart itself borrowing from places,
+/// e.g. `&[u8]` is a valid cart, as is `Box<&[u8]>`. `C` is not `'static`.
+///
+/// (I'm going to use `CT` in prose to refer to `C::Target` here, since almost everything here has to do
+/// with C::Target and not C itself.)
+///
+/// Unfortunately, there's a sneaky additional bound inside `F`. The signature of `F` is *actually*
+///
+/// ```rust,ignore
+/// F: for<'de> where<C::Target: 'de> FnOnce(&'de C::Target) -> <Y as Yokeable<'de>>::Output
+/// ```
+///
+/// using made-up "where clause inside HRTB" syntax to represent a type that can be represented inside the compiler
+/// and type system but not in Rust code. The `CT: 'de` bond comes from the `&'de C::Target`: any time you
+/// write `&'a T`, an implied bound of `T: 'a` materializes and is stored alongside it, since references cannot refer
+/// to data that itself refers to data of shorter lifetimes. If a reference is valid, its referent must be valid for
+/// the duration of the reference's lifetime, so every reference *inside* its referent must also be valid, giving us `T: 'a`.
+/// This kind of constraint is often called a "well formedness" constraint: `&'a T` is not "well formed" without that
+/// bound, and rustc is being helpful by giving it to us for free.
+///
+/// Unfortunately, this messes with our universal quantification. The `for<'de>` is no longer "For all lifetimes `'de`",
+/// it is "for all lifetimes `'de` *where `CT: 'de`*". And if `CT` borrows from somewhere (with lifetime `'ct`), then we get a
+/// `'ct: 'de` bound, and `'de` candidates that live longer than `'ct` won't actually be considered.
+/// The neat little logic at the beginning stops working.
+///
+/// `attach_to_cart()` will instead enforce that the produced yokeable *either* borrows from the cart (fine), or from
+/// data that has a lifetime that is at least `'ct`. Which means that `attach_to_cart()` will allow us to borrow locals
+/// provided they live at least as long as `'ct`.
+///
+/// Is this a problem?
+///
+/// This is totally fine if CT's lifetime is covariant: if C is something like `Box<&'ct [u8]>`, even if our
+/// yoked object borrows from locals outliving `'ct`, our Yoke can't outlive that
+/// lifetime `'ct` anyway (since it's a part of the cart type), so we're fine.
+///
+/// However it's completely broken for contravariant carts (e.g. `Box<fn(&'ct u8)>`). In that case
+/// we still get `'ct: 'de`, and we still end up being able to
+/// borrow from locals that outlive `'ct`. However, our Yoke _can_ outlive
+/// that lifetime, because Yoke shares its variance over `'ct`
+/// with the cart type, and the cart type is contravariant over `'ct`.
+/// So the Yoke can be upcast to having a longer lifetime than `'ct`, and *that* Yoke
+/// can outlive `'ct`.
+///
+/// We fix this by forcing `C::Target: 'static` in `attach_to_cart()`, which would make it work
+/// for fewer types, but would also allow Yoke to continue to be covariant over cart lifetimes if necessary.
+///
+/// An alternate fix would be to not allowing yoke to ever be upcast over lifetimes contained in the cart
+/// by forcing them to be invariant. This is a bit more restrictive and affects *all* `Yoke` users, not just
+/// those using `attach_to_cart()`.
+///
+/// See https://github.com/unicode-org/icu4x/issues/2926
+/// See also https://github.com/rust-lang/rust/issues/106431 for potentially fixing this upstream by
+/// changing how the bound works.
+///
+/// # Tests
+///
+/// Here's a broken `attach_to_cart()` that attempts to borrow from a local:
+///
+/// ```rust,compile_fail
+/// use yoke::{Yoke, Yokeable};
+///
+/// let cart = vec![1, 2, 3, 4].into_boxed_slice();
+/// let local = vec![4, 5, 6, 7];
+/// let yoke: Yoke<&[u8], Box<[u8]>> = Yoke::attach_to_cart(cart, |_| &*local);
+/// ```
+///
+/// Fails as expected.
+///
+/// And here's a working one with a local borrowed cart that does not do any sneaky borrows whilst attaching.
+///
+/// ```rust
+/// use yoke::{Yoke, Yokeable};
+///
+/// let cart = vec![1, 2, 3, 4].into_boxed_slice();
+/// let local = vec![4, 5, 6, 7];

+/// Here's an `attach_to_cart()` that attempts to borrow from a longer-lived local due to
+/// the cart being covariant. It fails, but would not if the alternate fix of forcing Yoke to be invariant
+/// were implemented. It is technically a safe operation:
+///
+/// ```rust,compile_fail
+/// use yoke::{Yoke, Yokeable};
+/// // longer lived
+/// let local = vec![4, 5, 6, 7];
+///
+/// let backing = vec![1, 2, 3, 4];
+/// let cart = Box::new(&*backing);
+///
+/// let yoke: Yoke<&[u8], Box<&[u8]>> = Yoke::attach_to_cart(cart, |_| &*local);
+/// println!("{:?}", yoke.get());
+/// ```
+///
+/// Finally, here's an `attach_to_cart()` that attempts to borrow from a longer lived local
+/// in the case of a contravariant lifetime. It does not compile, but in and of itself is not dangerous:
+///
+/// ```rust,compile_fail
+/// use yoke::Yoke;
+///
+/// type Contra<'a> = fn(&'a ());
+///
+/// let local = String::from("Hello World!");
+/// let yoke: Yoke<&'static str, Box<Contra<'_>>> = Yoke::attach_to_cart(Box::new((|_| {}) as _), |_| &local[..]);
+/// println!("{:?}", yoke.get());
+/// ```
+///
+/// It is dangerous if allowed to transform (testcase from #2926)
+///
+/// ```rust,compile_fail
+/// use yoke::Yoke;
+///
+/// type Contra<'a> = fn(&'a ());
+///
+///
+/// let local = String::from("Hello World!");
+/// let yoke: Yoke<&'static str, Box<Contra<'_>>> = Yoke::attach_to_cart(Box::new((|_| {}) as _), |_| &local[..]);
+/// println!("{:?}", yoke.get());
+/// let yoke_longer: Yoke<&'static str, Box<Contra<'static>>> = yoke;
+/// let leaked: &'static Yoke<&'static str, Box<Contra<'static>>> = Box::leak(Box::new(yoke_longer));
+/// let reference: &'static str = leaked.get();
+///
+/// println!("pre-drop: {reference}");

## Cargo features
-This crate has five optional features:
+This crate has several optional Cargo features:
- `serde`: Allows serializing and deserializing `zerovec`'s abstractions via [`serde`](https://docs.rs/serde)
- `yoke`: Enables implementations of `Yokeable` from the [`yoke`](https://docs.rs/yoke/) crate, which is also useful
in situations involving a lot of zero-copy deserialization.

+## [0.6.4]
+
+### Changed
+
+ - [#333](https://github.com/zip-rs/zip/pull/333): disabled the default features of the `time` dependency, and also `formatting` and `macros`, as they were enabled by mistake.
+ - Deprecated [`DateTime::from_time`](https://docs.rs/zip/0.6/zip/struct.DateTime.html#method.from_time) in favor of [`DateTime::try_from`](https://docs.rs/zip/0.6/zip/struct.DateTime.html#impl-TryFrom-for-DateTime)
+ \ No newline at end of file
