A DEFLATE-based stream compression/decompression library -//! -//! This library provides support for compression and decompression of -//! DEFLATE-based streams: -//! -//! * the DEFLATE format itself -//! * the zlib format -//! * gzip -//! -//! These three formats are all closely related and largely only differ in their -//! headers/footers. This crate has three types in each submodule for dealing -//! with these three formats. -//! -//! # Implementation -//! -//! In addition to supporting three formats, this crate supports several different -//! backends, controlled through this crate's features: -//! -//! * `default`, or `rust_backend` - this implementation uses the `miniz_oxide` -//! crate which is a port of `miniz.c` (below) to Rust. This feature does not -//! require a C compiler and only requires Rust code. -//! -//! * `zlib` - this feature will enable linking against the `libz` library, typically found on most -//! Linux systems by default. If the library isn't found to already be on the system it will be -//! compiled from source (this is a C library). -//! -//! There's various tradeoffs associated with each implementation, but in general you probably -//! won't have to tweak the defaults. The default choice is selected to avoid the need for a C -//! compiler at build time. `zlib-ng-compat` is useful if you're using zlib for compatibility but -//! want performance via zlib-ng's zlib-compat mode. `zlib` is useful if something else in your -//! dependencies links the original zlib so you cannot use zlib-ng-compat. The compression ratios -//! and performance of each of these feature should be roughly comparable, but you'll likely want -//! to run your own tests if you're curious about the performance. -//! -//! # Organization -//! -//! This crate consists mainly of three modules, [`read`], [`write`], and -//! [`bufread`]. Each module contains a number of types used to encode and -//! decode various streams of data. -//! -//! All types in the [`write`] module work on instances of [`Write`][write], -//! whereas all types in the [`read`] module work on instances of -//! [`Read`][read] and [`bufread`] works with [`BufRead`][bufread]. If you -//! are decoding directly from a `&[u8]`, use the [`bufread`] types. -//! -//! ``` -//! use flate2::write::GzEncoder; -//! use flate2::Compression; -//! use std::io; -//! use std::io::prelude::*; -//! -//! # fn main() { let _ = run(); } -//! # fn run() -> io::Result<()> { -//! let mut encoder = GzEncoder::new(Vec::new(), Compression::default()); -//! encoder.write_all(b"Example")?; -//! # Ok(()) -//! # } -//! ``` -//! -//! -//! Other various types are provided at the top-level of the crate for -//! management and dealing with encoders/decoders. Also note that types which -//! operate over a specific trait often implement the mirroring trait as well. -//! For example a `flate2::read::DeflateDecoder` *also* implements the -//! `Write` trait if `T: Write`. That is, the "dual trait" is forwarded directly -//! to the underlying object if available. -//! -//! # About multi-member Gzip files -//! -//! While most `gzip` files one encounters will have a single *member* that can be read -//! with the [`GzDecoder`], there may be some files which have multiple members. -//! -//! A [`GzDecoder`] will only read the first member of gzip data, which may unexpectedly -//! provide partial results when a multi-member gzip file is encountered. `GzDecoder` is appropriate -//! for data that is designed to be read as single members from a multi-member file. `bufread::GzDecoder` -//! and `write::GzDecoder` also allow non-gzip data following gzip data to be handled. -//! -//! The [`MultiGzDecoder`] on the other hand will decode all members of a `gzip` file -//! into one consecutive stream of bytes, which hides the underlying *members* entirely. -//! If a file contains contains non-gzip data after the gzip data, MultiGzDecoder will -//! emit an error after decoding the gzip data. This behavior matches the `gzip`, -//! `gunzip`, and `zcat` command line tools. -//! -//! [`read`]: read/index.html -//! [`bufread`]: bufread/index.html -//! [`write`]: write/index.html -//!
