# rust-lzma [](https://travis-ci.org/fpgaminer/rust-lzma) [](https://crates.io/crates/rust-lzma) #
[Documentation](https://docs.rs/rust-lzma/)
This crate provides a simple interface to liblzma. LZMA is more commonly known
as XZ or 7zip, (as in, files with the `.xz` or `.7z` file extension). LZMA
compression is fast and aggressive, compressing better than bzip2. liblzma
implements the XZ variant, so it can read and write `.xz` files/streams.
Two interfaces are provided. `LzmaReader`/`LzmaWriter` are generic Readers and
Writers that can be composed with other `Read`/`Write` interfaces. For example,
wrap them around a `File` and you can write data to a file while compressing it
on the fly, or stream in an `xz` file from disk.
`compress`/`decompress` are easy to use functions for simple use cases.
See the documentation for details on usage.
## Example ##
Cargo.toml:
```toml
[dependencies]
rust-lzma = "0.5"
```
main.rs:
```Rust
extern crate lzma;
use lzma::LzmaWriter;
use std::io::prelude::*;
use std::fs::File;
fn main() {
let f = File::create("foo.xz").unwrap();
let mut f = LzmaWriter::new_compressor(f, 6).unwrap();
write!(f, "It's a small world!").unwrap();
f.finish().unwrap();
}
```
