-//! A pure rust replacement for the [miniz](https://github.com/richgel999/miniz)
-//! DEFLATE/zlib encoder/decoder.
-//! Used a rust back-end for the
-//! [flate2](https://github.com/alexcrichton/flate2-rs) crate.
-//!
-//! # Usage
-//! ## Simple compression/decompression:
-//! ``` rust
-//!
-//! use miniz_oxide::inflate::decompress_to_vec;
-//! use miniz_oxide::deflate::compress_to_vec;
-//!
-//! fn roundtrip(data: &[u8]) {
-//! let compressed = compress_to_vec(data, 6);
-//! let decompressed = decompress_to_vec(compressed.as_slice()).expect("Failed to decompress!");
-//! # let _ = decompressed;
-//! }
-//!
-//! # roundtrip(b"Test_data test data lalalal blabla");
-//!
-//! ```
