A Rust implementation of DEFLATE algorithm and related formats (ZLIB, GZIP).

Documentation

See RustDoc Documentation.

The documentation includes some examples.

Installation

Add following lines to your Cargo.toml:

[dependencies]
libflate = "2"

An Example

Below is a command to decode GZIP stream that is read from the standard input:

extern crate libflate;

use std::io;
use libflate::gzip::Decoder;

fn main() {
    let mut input = io::stdin();
    let mut decoder = Decoder::new(&mut input).unwrap();
    io::copy(&mut decoder, &mut io::stdout()).unwrap();
}

An Informal Benchmark

A brief comparison with flate2 and inflate:

$ cd libflate/flate_bench/
$ curl -O https://dumps.wikimedia.org/enwiki/latest/enwiki-latest-all-titles-in-ns0.gz
$ gzip -d enwiki-latest-all-titles-in-ns0.gz
> ls -lh enwiki-latest-all-titles-in-ns0
-rw-rw-r-- 1 foo foo 265M May 18 05:19 enwiki-latest-all-titles-in-ns0

$ cargo run --release -- enwiki-latest-all-titles-in-ns0
