-//! # LZW decoder and encoder
-//!
-//! This crates provides an `Encoder` and a `Decoder` in their respective modules. The code words
-//! are written from and to bit byte slices (or streams) where it is possible to write either the
-//! most or least significant bits first. The maximum possible code size is 12 bits, the smallest
-//! available code size is 2 bits.
-//!
-//! ## Example
-//!
-//! These two code blocks show the compression and corresponding decompression. Note that you must
-//! use the same arguments to `Encoder` and `Decoder`, otherwise the decoding might fail or produce
-//! bad results.
-//!
-#![cfg_attr(feature = "std", doc = "```")]
-#![cfg_attr(not(feature = "std"), doc = "```ignore")]
-//! use weezl::{BitOrder, encode::Encoder};
-//!
-//! let data = b"Hello, world";
-//! let compressed = Encoder::new(BitOrder::Msb, 9)
-//!     .encode(data)
-//!     .unwrap();
-//! ```
-//!
-#![cfg_attr(feature = "std", doc = "```")]
-#![cfg_attr(not(feature = "std"), doc = "```ignore")]
-//! use weezl::{BitOrder, decode::Decoder};
-//! # let compressed = b"\x80\x04\x81\x94l\x1b\x06\xf0\xb0 \x1d\xc6\xf1\xc8l\x19 \x10".to_vec();
-//! # let data = b"Hello, world";
-//!
-//! let decompressed = Decoder::new(BitOrder::Msb, 9)
-//!     .decode(&compressed)
-//!     .unwrap();
-//! assert_eq!(decompressed, data);
-//! ```
-//!
-//! ## LZW Details
-//!
-//! The de- and encoder expect the LZW stream to start with a clear code and end with an
-//! end code which are defined as follows:
-//!
-//!  * `CLEAR_CODE == 1 << min_code_size`
-//!  * `END_CODE   == CLEAR_CODE + 1`
-//!
-//! For optimal performance, all buffers and input and output slices should be as large as possible
-//! and at least 2048 bytes long. This extends to input streams which should have similarly sized
-//! buffers. This library uses Rust's standard allocation interfaces (`Box` and `Vec` to be
-//! precise). Since there are no ways to handle allocation errors it is not recommended to operate
-//! it on 16-bit targets.
-//!
-//! ## Allocations and standard library
-//!
-//! The main algorithm can be used in `no_std` as well, although it requires an allocator. This
-//! restriction might be lifted at a later stage. For this you should deactivate the `std` feature.
-//! The main interfaces stay intact but the `into_stream` combinator is no available.
