Extended utilities for working with files and filesystems in Rust. fs2 requires Rust stable 1.8 or greater.

• file descriptor duplication.
• file locks.
• file (pre)allocation.
• file allocation information.
• filesystem space usage information.

fs2 should work on any platform supported by libc.

fs2 is continuously tested on:

• x86_64-unknown-linux-gnu (Linux)
• i686-unknown-linux-gnu
• x86_64-apple-darwin (OSX)
• i686-apple-darwin
• x86_64-pc-windows-msvc (Windows)
• i686-pc-windows-msvc
• x86_64-pc-windows-gnu
• i686-pc-windows-gnu

Simple benchmarks are provided for the methods provided. Many of these benchmarks use files in a temporary directory. On many modern Linux distros the default temporary directory, /tmp, is mounted on a tempfs filesystem, which will have different performance characteristics than a disk-backed filesystem. The temporary directory is configurable at runtime through the environment (see env::temp_dir).

fs2 is primarily distributed under the terms of both the MIT license and the Apache License (Version 2.0).

See LICENSE-APACHE, LICENSE-MIT for details.
