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
