//! Rust binding to the [zstd library][zstd].
//!
//! This crate provides:
//!
//! * An [encoder](struct.Encoder.html) to compress data using zstd and send the output to another write.
//! * A [decoder](struct.Decoder.html) to read input data from a `Read` and decompress it.
//!
//! # Example
//!
//! ```rust
//! extern crate zstd;
//!
//! use std::io;
//!
//! fn main() {
//! 	// Uncompress input and print the result.
//! 	let mut decoder = zstd::Decoder::new(io::stdin()).unwrap();
//! 	io::copy(&mut decoder, &mut io::stdout()).unwrap();
//! }
//! ```
//!
//! [zstd]: https://github.com/Cyan4973/zstd
