Crate deflate

An implementation an encoder using DEFLATE compression algorightm in pure rust.

This library provides functions to compress data using the DEFLATE algorithm, optionally wrapped using the zlib or gzip formats. The current implementation is still a bit lacking speed-wise compared to C-libraries like zlib and miniz.

Support for the gzip wrapper is disabled by default, but can be enabled with the gzip feature.

As this library is still in development, the compression output may change slightly between versions.

Examples:

Simple compression function:

use deflate::deflate_bytes;

let data = b"Some data";
let compressed = deflate_bytes(data);

Using a writer:

use std::io::Write;

use deflate::Compression;
use deflate::write::ZlibEncoder;

let data = b"This is some test data";
let mut encoder = ZlibEncoder::new(Vec::new(), Compression::Default);
encoder.write_all(data).unwrap();
let compressed_data = encoder.finish().unwrap();

Modules

write

Encoders implementing a Write interface.

Structs

CompressionOptions

A struct describing the options for a compressor or compression function.

Enums

Compression	An enum describing the level of compression to be used by the encoder
MatchingType	An enum describing whether we use lazy or greedy matching.
SpecialOptions	Enum allowing some special options (not implemented yet)!

Functions

deflate_bytes	Compress the given slice of bytes with DEFLATE compression using the default compression level.
deflate_bytes_conf	Compress the given slice of bytes with DEFLATE compression.
deflate_bytes_zlib	Compress the given slice of bytes with DEFLATE compression, including a zlib header and trailer, using the default compression level.
deflate_bytes_zlib_conf	Compress the given slice of bytes with DEFLATE compression, including a zlib header and trailer.
