SLoC
LZMA/LZMA2 codec ported from tukaani xz for java
Usage
lzma
use std::io::{Read, Write};
use lzma_rust::*;
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[..]);
