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.

## Usage

Decompress a `.xz` file.

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

## Encoder

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!

## Contributing

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