+3.2.0
+=====
+
+Features:
+
+* Bump rand dependency to `0.8`.
+* Bump cfg-if dependency to `1.0`
+
+Other than that, this release mostly includes small cleanups and simplifications.
+
+Breaking: The minimum rust version is now `1.40.0`.
+
+3.1.0
+=====
+
+Features:
+
+* Bump rand dependency to `0.7`.
+
+Breaking: The minimum rust version is now `1.32.0`.
+
+3.0.9
+=====
+
+Documentation:
+
+* Add an example for reopening a named temporary file.
+* Flesh out the security documentation.
+
+Features:
+
+* Introduce an `append` option to the builder.
+* Errors:
+ * No longer implement the soft-deprecated `description`.
+ * Implement `source` instead of `cause`.
+
+Breaking: The minimum rust version is now 1.30.
+
+3.0.8
+=====
+
+This is a bugfix release.
+
+Fixes:
+
+* Export `PathPersistError`.
+* Fix a bug where flushing a `SpooledTempFile` to disk could fail to write part
+ of the file in some rare, yet-to-reproduced cases.
+
+3.0.7
+=====
+
+Breaking:
+
+* `Builder::prefix` and `Builder::suffix` now accept a generic `&AsRef<OsStr>`.
+ This could affect type inference.
+* Temporary files (except unnamed temporary files on Windows and Linux >= 3.11)
+ now use absolute path names. This will break programs that create temporary
+ files relative to their current working directory when they don't have the
+ search permission (x) on some ancestor directory. This is only likely to
+ affect programs with strange chroot-less filesystem sandboxes. If you believe
+ you're affected by this issue, please comment on #40.
+
+Features:
+
+* Accept anything implementing `&AsRef<OsStr>` in the builder: &OsStr, &OsString, &Path, etc.
+
+Fixes:
+
+* Fix LFS support.
+* Use absolute paths for named temporary files to guard against changes in the
+ current directory.
+* Use absolute paths when creating unnamed temporary files on platforms that
+ can't create unlinked or auto-deleted temporary files. This fixes a very
+ unlikely race where the current directory could change while the temporary
+ file is being created.
+
+Misc:
+
+* Use modern stdlib features to avoid custom unsafe code. This reduces the
+ number of unsafe blocks from 12 to 4.
+
+3.0.6
+=====
+
+* Don't hide temporary files on windows, fixing #66 and #69.
+
+3.0.5
+=====
+
+Features:
+
+* Added a spooled temporary file implementation. This temporary file variant
+ starts out as an in-memory temporary file but "rolls-over" onto disk when it
+ grows over a specified size (#68).
+* Errors are now annotated with paths to make debugging easier (#73).
+
+Misc:
+
+* The rand version has been bumped to 0.6 (#74).
+
+Bugs:
+
+* Tempfile compiles again on Redox (#75).
+
+3.0.4
+=====
+
+* Now compiles on unsupported platforms.
+
+3.0.3
+=====
+
+* update rand to 0.5
+
+3.0.2
+=====
+
+* Actually *delete* temporary files on non-Linux unix systems (thanks to
+@oliverhenshaw for the fix and a test case).
+
+3.0.1
+=====
+
+* Restore NamedTempFile::new_in
+
+3.0.0
+=====
+
+* Adds temporary directory support (@KodrAus)
+* Allow closing named temporary files without deleting them (@jasonwhite)
+
+2.2.0
+=====
+
+* Redox Support
+
+2.1.6
+=====
+
+* Remove build script and bump minimum rustc version to 1.9.0
+
+2.1.5
+=====
+
+* Don't build platform-specific dependencies on all platforms.
+* Cleanup some documentation.
+
+2.1.4
+=====
+
+* Fix crates.io tags. No interesting changes.
+
+2.1.3
+=====
+
+Export `PersistError`.
+
+2.1.2
+=====
+
+Add `Read`/`Write`/`Seek` impls on `&NamedTempFile`. This mirrors the
+implementations on `&File`. One can currently just deref to a `&File` but these
+implementations are more discoverable.
+
+2.1.1
+=====
+
+Add LFS Support.
+
+2.1.0
+=====
+
+* Implement `AsRef<File>` for `NamedTempFile` allowing named temporary files to
+ be borrowed as `File`s.
+* Add a method to convert a `NamedTempFile` to an unnamed temporary `File`.
+
+2.0.1
+=====
+
+* Arm bugfix
+
+2.0.0
+=====
+
+This release replaces `TempFile` with a `tempfile()` function that returnes
+`std::fs::File` objects. These are significantly more useful because most rust
+libraries expect normal `File` objects.
+
+To continue supporting shared temporary files, this new version adds a
+`reopen()` method to `NamedTempFile`.

+[![Build status](https://ci.appveyor.com/api/projects/status/5q00b8rvvg46i5tf/branch/master?svg=true)](https://ci.appveyor.com/project/Stebalien/tempfile/branch/master)
+
+A secure, cross-platform, temporary file library for Rust. In addition to creating
+temporary files, this library also allows users to securely open multiple
+independent references to the same temporary file (useful for consumer/producer
+patterns and surprisingly difficult to implement securely).
+
+[Documentation](https://docs.rs/tempfile/)
+
+Usage
+-----
+
+Minimum required Rust version: 1.40.0
+
+Add this to your `Cargo.toml`:
+```toml
+[dependencies]
+tempfile = "3"
+```
+
+Example
+-------
+
+```rust
+use std::fs::File;
+use std::io::{Write, Read, Seek, SeekFrom};
+
+fn main() {
+ // Write
+ let mut tmpfile: File = tempfile::tempfile().unwrap();
+ write!(tmpfile, "Hello World!").unwrap();
+
+ // Seek to start
+ tmpfile.seek(SeekFrom::Start(0)).unwrap();
+
+ // Read
+ let mut buf = String::new();
+ tmpfile.read_to_string(&mut buf).unwrap();
+ assert_eq!("Hello World!", buf);
+}

+
+/// A directory in the filesystem that is automatically deleted when
+/// it goes out of scope.
+///
+/// The [`TempDir`] type creates a directory on the file system that
+/// is deleted once it goes out of scope. At construction, the
+/// `TempDir` creates a new directory with a randomly generated name.
+///
+/// The default constructor, [`TempDir::new()`], creates directories in
+/// the location returned by [`std::env::temp_dir()`], but `TempDir`
+/// can be configured to manage a temporary directory in any location
+/// by constructing with a [`Builder`].
+///
+/// After creating a `TempDir`, work with the file system by doing
+/// standard [`std::fs`] file system operations on its [`Path`],
+/// which can be retrieved with [`TempDir::path()`]. Once the `TempDir`
+/// value is dropped, the directory at the path will be deleted, along
+/// with any files and directories it contains. It is your responsibility
+/// to ensure that no further file system operations are attempted
+/// inside the temporary directory once it has been deleted.
+///
+/// # Resource Leaking
+///
+/// Various platform-specific conditions may cause `TempDir` to fail
+/// to delete the underlying directory. It's important to ensure that
+/// handles (like [`File`] and [`ReadDir`]) to files inside the
+/// directory are dropped before the `TempDir` goes out of scope. The
+/// `TempDir` destructor will silently ignore any errors in deleting
+/// the directory; to instead handle errors call [`TempDir::close()`].
+///
+/// Note that if the program exits before the `TempDir` destructor is
+/// run, such as via [`std::process::exit()`], by segfaulting, or by
+/// receiving a signal like `SIGINT`, then the temporary directory
+/// will not be deleted.
+///
+/// # Examples
+///
+/// Create a temporary directory with a generated name:
+///
+/// ```
+/// use std::fs::File;
+/// use std::io::Write;
+/// use tempfile::TempDir;
+///
+/// # use std::io;
+/// # fn run() -> Result<(), io::Error> {
+/// // Create a directory inside of `std::env::temp_dir()`
+/// let tmp_dir = TempDir::new()?;
+/// # Ok(())
+/// # }
+/// ```
+///
+/// Create a temporary directory with a prefix in its name:
+///
+/// ```
+/// use std::fs::File;
+/// use std::io::Write;
+/// use tempfile::Builder;
+///
+/// # use std::io;
+/// # fn run() -> Result<(), io::Error> {
+/// // Create a directory inside of `std::env::temp_dir()`,
+/// // whose name will begin with 'example'.
+/// let tmp_dir = Builder::new().prefix("example").tempdir()?;

+/// can be configured to manage a temporary file in any location
+/// by constructing with [`NamedTempFile::new_in()`].
+///
+/// # Security
+///
+/// Most operating systems employ temporary file cleaners to delete old
+/// temporary files. Unfortunately these temporary file cleaners don't always
+/// reliably _detect_ whether the temporary file is still being used.
+///
+/// Specifically, the following sequence of events can happen:
+///
+/// 1. A user creates a temporary file with `NamedTempFile::new()`.
+/// 2. Time passes.
+/// 3. The temporary file cleaner deletes (unlinks) the temporary file from the
+/// filesystem.
+/// 4. Some other program creates a new file to replace this deleted temporary
+/// file.
+/// 5. The user tries to re-open the temporary file (in the same program or in a
+/// different program) by path. Unfortunately, they'll end up opening the
+/// file created by the other program, not the original file.
+///
+/// ## Operating System Specific Concerns
+///
+/// The behavior of temporary files and temporary file cleaners differ by
+/// operating system.
+///
+/// ### Windows
+///
+/// On Windows, open files _can't_ be deleted. This removes most of the concerns
+/// around temporary file cleaners.
+///
+/// Furthermore, temporary files are, by default, created in per-user temporary
+/// file directories so only an application running as the same user would be
+/// able to interfere (which they could do anyways). However, an application
+/// running as the same user can still _accidentally_ re-create deleted
+/// temporary files if the number of random bytes in the temporary file name is
+/// too small.
+///
+/// So, the only real concern on Windows is:
+///
+/// 1. Opening a named temporary file in a world-writable directory.
+/// 2. Using the `into_temp_path()` and/or `into_parts()` APIs to close the file
+/// handle without deleting the underlying file.
+/// 3. Continuing to use the file by path.
+///
+/// ### UNIX
+///
+/// Unlike on Windows, UNIX (and UNIX like) systems allow open files to be
+/// "unlinked" (deleted).
+///
+/// #### MacOS
+///
+/// Like on Windows, temporary files are created in per-user temporary file
+/// directories by default so calling `NamedTempFile::new()` should be
+/// relatively safe.
+///
+/// #### Linux
+///
+/// Unfortunately, most _Linux_ distributions don't create per-user temporary
+/// file directories. Worse, systemd's tmpfiles daemon (a common temporary file
+/// cleaner) will happily remove open temporary files if they haven't been
+/// modified within the last 10 days.
+///
+/// # Resource Leaking
+///
+/// If the program exits before the `NamedTempFile` destructor is
+/// run, such as via [`std::process::exit()`], by segfaulting, or by
+/// receiving a signal like `SIGINT`, then the temporary file
+/// will not be deleted.
+///
+/// Use the [`tempfile()`] function unless you absolutely need a named file.

+//! Temporary files and directories.
+//!
+//! - Use the [`tempfile()`] function for temporary files
+//! - Use the [`tempdir()`] function for temporary directories.
+//!
+//! # Design
+//!
+//! This crate provides several approaches to creating temporary files and directories.
+//! [`tempfile()`] relies on the OS to remove the temporary file once the last handle is closed.
+//! [`TempDir`] and [`NamedTempFile`] both rely on Rust destructors for cleanup.
+//!
+//! When choosing between the temporary file variants, prefer `tempfile`
+//! unless you either need to know the file's path or to be able to persist it.
+//!
+//! ## Resource Leaking
+//!
+//! `tempfile` will (almost) never fail to cleanup temporary resources, but `TempDir` and `NamedTempFile` will if
+//! their destructors don't run. This is because `tempfile` relies on the OS to cleanup the
+//! underlying file, while `TempDir` and `NamedTempFile` rely on their destructors to do so.
+//!
+//! ## Security
+//!
+//! In the presence of pathological temporary file cleaner, relying on file paths is unsafe because
+//! a temporary file cleaner could delete the temporary file which an attacker could then replace.
+//!
+//! `tempfile` doesn't rely on file paths so this isn't an issue. However, `NamedTempFile` does
+//! rely on file paths for _some_ operations. See the security documentation on
+//! the `NamedTempFile` type for more information.
+//!
+//! ## Examples
+//!
+//! Create a temporary file and write some data into it:
+//!
+//! ```
+//! use tempfile::tempfile;
+//! use std::io::{self, Write};
+//!
+//! # fn main() {
+//! # if let Err(_) = run() {
+//! # ::std::process::exit(1);
+//! # }
+//! # }
+//! # fn run() -> Result<(), io::Error> {
+//! // Create a file inside of `std::env::temp_dir()`.
+//! let mut file = tempfile()?;
+//!
+//! writeln!(file, "Brian was here. Briefly.")?;
+//! # Ok(())
+//! # }
+//! ```
+//!
+//! Create a named temporary file and open an independent file handle:
+//!
+//! ```
+//! use tempfile::NamedTempFile;
+//! use std::io::{self, Write, Read};
+//!
+//! # fn main() {
+//! # if let Err(_) = run() {
+//! # ::std::process::exit(1);
+//! # }
+//! # }
+//! # fn run() -> Result<(), io::Error> {
+//! let text = "Brian was here. Briefly.";
+//!
+//! // Create a file inside of `std::env::temp_dir()`.
+//! let mut file1 = NamedTempFile::new()?;
+//!
+//! // Re-open it.
+//! let mut file2 = file1.reopen()?;
+//!
+//! // Write some test data to the first handle.
+//! file1.write_all(text.as_bytes())?;
+//!
+//! // Read the test data using the second handle.
+//! let mut buf = String::new();
+//! file2.read_to_string(&mut buf)?;
+//! assert_eq!(buf, text);
+//! # Ok(())
+//! # }
+//! ```
+//!
+//! Create a temporary directory and add a file to it:
+//!
+//! ```
+//! use tempfile::tempdir;
+//! use std::fs::File;
+//! use std::io::{self, Write};
+//!
+//! # fn main() {
+//! # if let Err(_) = run() {
+//! # ::std::process::exit(1);
+//! # }
+//! # }
+//! # fn run() -> Result<(), io::Error> {
+//! // Create a directory inside of `std::env::temp_dir()`.
+//! let dir = tempdir()?;
+//!
+//! let file_path = dir.path().join("my-temporary-note.txt");
+//! let mut file = File::create(file_path)?;
+//! writeln!(file, "Brian was here. Briefly.")?;
+//!
+//! // By closing the `TempDir` explicitly, we can check that it has
+//! // been deleted successfully. If we don't close it explicitly,
+//! // the directory will still be deleted when `dir` goes out
+//! // of scope, but we won't know whether deleting the directory
+//! // succeeded.
+//! drop(file);
+//! dir.close()?;
+//! # Ok(())
+//! # }
+//! ```
