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 = 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.
