-1.3.4
-=====
-This patch release squashes deprecation warnings for the `try!` macro, in
-accordance with byteorder's minimum supported Rust version (currently at Rust
-1.12.0).
-
-
-1.3.3
-=====
-This patch release adds `ByteOrder::write_i8_into()` as a simple, safe interface
-for ordinarily unsafe or tedious code.
-
-
-1.3.2
-=====
-This patch release adds `ReadBytesExt::read_i8_into()` as a simple, safe interface
-for ordinarily unsafe or tedious code.
-
-
-1.3.1
-=====
-This minor release performs mostly small internal changes. Going forward, these
-are not going to be incorporated into the changelog.
-
-
-1.3.0
-=====
-This new minor release now enables `i128` support automatically on Rust
-compilers that support 128-bit integers. The `i128` feature is now a no-op, but
-continues to exist for backward compatibility purposes. The crate continues to
-maintain compatibility with Rust 1.12.0.
-
-This release also deprecates the `ByteOrder` trait methods
-`read_f32_into_unchecked` and `read_f64_into_unchecked` in favor of
-`read_f32_into` and `read_f64_into`. This was an oversight from the 1.2 release
-where the corresponding methods on `ReadBytesExt` were deprecated.
-
-`quickcheck` and `rand` were bumped to `0.8` and `0.6`, respectively.
-
-A few small documentation related bugs have been fixed.
-
-
-1.2.7
-=====
-This patch release excludes some CI files from the crate release and updates
-the license field to use `OR` instead of `/`.
-
-
-1.2.6
-=====
-This patch release fixes some test compilation errors introduced by an
-over-eager release of 1.2.5.
-
-
-1.2.5
-=====
-This patch release fixes some typos in the docs, adds doc tests to methods on
-`WriteByteExt` and bumps the quickcheck dependency to `0.7`.
-
-
-1.2.4
-=====
-This patch release adds support for 48-bit integers by adding the following
-methods to the `ByteOrder` trait: `read_u48`, `read_i48`, `write_u48` and
-`write_i48`. Corresponding methods have been added to the `ReadBytesExt` and
-`WriteBytesExt` traits as well.
-
-
-1.2.3
-=====
-This patch release removes the use of `feature(i128_type)` from byteorder,
-since it has been stabilized. We leave byteorder's `i128` feature in place
-in order to continue supporting compilation on older versions of Rust.
-
-
-1.2.2
-=====
-This patch release only consists of internal improvements and refactorings.
-Notably, this removes all uses of `transmute` and instead uses pointer casts.
-
-
-1.2.1
-=====
-This patch release removes more unnecessary uses of `unsafe` that
-were overlooked in the prior `1.2.0` release. In particular, the
-`ReadBytesExt::read_{f32,f64}_into_checked` methods have been deprecated and
-replaced by more appropriately named `read_{f32,f64}_into` methods.
-
-
-1.2.0
-=====
-The most prominent change in this release of `byteorder` is the removal of
-unnecessary signaling NaN masking, and in turn, the `unsafe` annotations
-associated with methods that didn't do masking. See
-[#103](https://github.com/BurntSushi/byteorder/issues/103)
-for more details.
-
-* [BUG #102](https://github.com/BurntSushi/byteorder/issues/102):
- Fix big endian tests.
-* [BUG #103](https://github.com/BurntSushi/byteorder/issues/103):
- Remove sNaN masking.
-
-
-1.1.0
-=====
-This release of `byteorder` features a number of fixes and improvements, mostly
-as a result of the
-[Litz Blitz evaluation](https://public.etherpad-mozilla.org/p/rust-crate-eval-byteorder).
-
-Feature enhancements:
-
-* [FEATURE #63](https://github.com/BurntSushi/byteorder/issues/63):
- Add methods for reading/writing slices of numbers for a specific
- endianness.
-* [FEATURE #65](https://github.com/BurntSushi/byteorder/issues/65):
- Add support for `u128`/`i128` types. (Behind the nightly only `i128`
- feature.)
-* [FEATURE #72](https://github.com/BurntSushi/byteorder/issues/72):
- Add "panics" and "errors" sections for each relevant public API item.
-* [FEATURE #74](https://github.com/BurntSushi/byteorder/issues/74):
- Add CI badges to Cargo.toml.
-* [FEATURE #75](https://github.com/BurntSushi/byteorder/issues/75):
- Add more examples to public API items.
-* Add 24-bit read/write methods.
-* Add `BE` and `LE` type aliases for `BigEndian` and `LittleEndian`,
- respectively.
-
-Bug fixes:
-
-* [BUG #68](https://github.com/BurntSushi/byteorder/issues/68):
- Panic in {BigEndian,LittleEndian}::default.
-* [BUG #69](https://github.com/BurntSushi/byteorder/issues/69):
- Seal the `ByteOrder` trait to prevent out-of-crate implementations.
-* [BUG #71](https://github.com/BurntSushi/byteorder/issues/71):
- Guarantee that the results of `read_f32`/`read_f64` are always defined.
-* [BUG #73](https://github.com/BurntSushi/byteorder/issues/73):
- Add crates.io categories.
-* [BUG #77](https://github.com/BurntSushi/byteorder/issues/77):
- Add `html_root` doc attribute.

-byteorder
-=========
-This crate provides convenience methods for encoding and decoding
-numbers in either big-endian or little-endian order.
-
-[![Build status](https://github.com/BurntSushi/byteorder/workflows/ci/badge.svg)](https://github.com/BurntSushi/byteorder/actions)
-[![](https://meritbadge.herokuapp.com/byteorder)](https://crates.io/crates/byteorder)
-
-Dual-licensed under MIT or the [UNLICENSE](https://unlicense.org/).
-
-
-### Documentation
-
-https://docs.rs/byteorder
-
-
-### Installation
-
-This crate works with Cargo and is on
-[crates.io](https://crates.io/crates/byteorder). Add it to your `Cargo.toml`
-like so:
-
-```toml
-[dependencies]
-byteorder = "1"
-```
-
-If you want to augment existing `Read` and `Write` traits, then import the
-extension methods like so:
-
-```rust
-use byteorder::{ReadBytesExt, WriteBytesExt, BigEndian, LittleEndian};
-```
-
-For example:
-
-```rust
-use std::io::Cursor;
-use byteorder::{BigEndian, ReadBytesExt};
-
-let mut rdr = Cursor::new(vec![2, 5, 3, 0]);
-// Note that we use type parameters to indicate which kind of byte order
-// we want!
-assert_eq!(517, rdr.read_u16::<BigEndian>().unwrap());
-assert_eq!(768, rdr.read_u16::<BigEndian>().unwrap());
-```
-
-### `no_std` crates
-
-This crate has a feature, `std`, that is enabled by default. To use this crate
-in a `no_std` context, add the following to your `Cargo.toml`:
-
-```toml
-[dependencies]
-byteorder = { version = "1", default-features = false }
-```
-
-
-### Alternatives
-
-Note that as of Rust 1.32, the standard numeric types provide built-in methods
-like `to_le_bytes` and `from_le_bytes`, which support some of the same use
-cases.

-/*!
-This crate provides convenience methods for encoding and decoding numbers in
-either [big-endian or little-endian order].
-
-The organization of the crate is pretty simple. A trait, [`ByteOrder`], specifies
-byte conversion methods for each type of number in Rust (sans numbers that have
-a platform dependent size like `usize` and `isize`). Two types, [`BigEndian`]
-and [`LittleEndian`] implement these methods. Finally, [`ReadBytesExt`] and
-[`WriteBytesExt`] provide convenience methods available to all types that
-implement [`Read`] and [`Write`].
-
-An alias, [`NetworkEndian`], for [`BigEndian`] is provided to help improve
-code clarity.
-
-An additional alias, [`NativeEndian`], is provided for the endianness of the
-local platform. This is convenient when serializing data for use and
-conversions are not desired.
-
-# Examples
-
-Read unsigned 16 bit big-endian integers from a [`Read`] type:
-
-```rust
-use std::io::Cursor;
-use byteorder::{BigEndian, ReadBytesExt};
-
-let mut rdr = Cursor::new(vec![2, 5, 3, 0]);
-// Note that we use type parameters to indicate which kind of byte order
-// we want!
-assert_eq!(517, rdr.read_u16::<BigEndian>().unwrap());
-assert_eq!(768, rdr.read_u16::<BigEndian>().unwrap());
-```
-
-Write unsigned 16 bit little-endian integers to a [`Write`] type:
-
-```rust
-use byteorder::{LittleEndian, WriteBytesExt};
-
-let mut wtr = vec![];
-wtr.write_u16::<LittleEndian>(517).unwrap();
-wtr.write_u16::<LittleEndian>(768).unwrap();
-assert_eq!(wtr, vec![5, 2, 0, 3]);
-```
-
-# Optional Features
-
-This crate optionally provides support for 128 bit values (`i128` and `u128`)
-when built with the `i128` feature enabled.
-
-This crate can also be used without the standard library.
-
-# Alternatives
-
-Note that as of Rust 1.32, the standard numeric types provide built-in methods
-like `to_le_bytes` and `from_le_bytes`, which support some of the same use
-cases.
