fs3

Extended utilities for working with files and filesystems in Rust. fs3 is a fork of fs2.

Features

[x] file descriptor duplication.
[x] file locks.
[x] file (pre)allocation.
[x] file allocation information.
[x] filesystem space usage information.

Platforms

fs3 should work on any platform supported by libc.

Benchmarks

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).
