This project is a decoder for LZMA and its variants written in pure Rust, with focus on clarity.It already supports LZMA, LZMA2 and a subset of the.xz file format.

Decompress a.xz file.

let filename ="foo.xz";letmut f = std::io::BufReader::new(std::fs::File::open(filename).unwrap());// "decomp" can be anything that implements "std::io::Write"letmut decomp:Vec<u8> =Vec::new();lzma_rs::xz_decompress(&mut f,&mut decomp).unwrap();// Decompressed content is now in "decomp"

For now, there is also a dumb encoder that only uses byte literals, with many hard-coded constants for code simplicity.Better encoders are welcome!

Pull-requests are welcome, to improve the decoder, add better encoders, or more tests.Ultimately, this project should also implement .xz and .7z files.
