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


See RustDoc Documentation.

The documentation includes some examples.


Add following lines to your Cargo.toml:

libflate = "0.1"

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
