lzma-rust2

LZMA/LZMA2 codec ported from tukaani xz for java.

This is a fork of the original, unmaintained lzma-rust crate to continue the development and maintenance.

Usage

lzma

use std::io::{Read, Write};
use lzma_rust2::*;

let s = b"Hello, world!";
let mut out = Vec::new();
let mut options = LZMA2Options::with_preset(6);
options.dict_size = LZMA2Options::DICT_SIZE_DEFAULT;

let mut w = LZMAWriter::new_use_header(CountingWriter::new( & mut out), & options, None).unwrap();
w.write_all(s).unwrap();
w.write( & []).unwrap();
let mut r = LZMAReader::new_mem_limit( & out[..], u32::MAX, None).unwrap();
let mut s2 = vec![0; s.len()];
r.read_exact( & mut s2).unwrap();
println!("{:?}", &out[..]);
assert_eq!(s, &s2[..]);
