[−][src]Crate async_compression

Adaptors between compression crates and Rust's modern asynchronous IO types.

Feature Organization

This crate is divided up along two axes, which can each be individually selected via Cargo features.

All features are disabled by default, you should enable just the ones you need from the lists below.

If you want to pull in everything there are three group features defined:

Feature	Does
`all`	Activates all implementations and algorithms.
`all-implementations`	Activates all implementations, needs to be pared with a selection of algorithms
`all-algorithms`	Activates all algorithms, needs to be pared with a selection of implementations

IO implementation

The first division is which underlying asynchronous IO trait will be wrapped, these are available as separate features that have corresponding top-level modules:

Feature	Type
`bufread`	`futures::io::AsyncBufRead`
`write`	`futures::io::AsyncWrite`
`stream`	`futures::stream::Stream<Item =` `std::io::Result<bytes::Bytes>>`

Compression algorithm

The second division is which compression schemes to support, there are currently a few available choices, these determine which types will be available inside the above modules:

Feature	Types
`brotli`	`BrotliEncoder`, `BrotliDecoder`
`bzip`	`BzEncoder`, `BzDecoder`
`deflate`	`DeflateEncoder`, `DeflateDecoder`
`gzip`	`GzipEncoder`, `GzipDecoder`
`zlib`	`ZlibEncoder`, `ZlibDecoder`
`zstd`	`ZstdEncoder`, `ZstdDecoder`

Modules

brotli2	`feature="brotli"` Types to configure `brotli2` based encoders.
bufread	`feature="bufread"` Types which operate over `AsyncBufRead` streams, both encoders and decoders for various formats.
bzip2	`feature="bzip"` Types to configure `bzip2` based encoders.
flate2	`feature="deflate"` or `feature="zlib"` or `feature="gzip"` Types to configure `flate2` based encoders.
stream	`feature="stream"` Types which operate over `Stream<Item =` `io::Result<Bytes>>` streams, both encoders and decoders for various formats.
write	`feature="write"` Types which operate over `AsyncWrite` streams, both encoders and decoders for various formats.
