Crate blosc

Rust bindings for the C-Blosc block-oriented compression library.

Blosc is a high performance compressor optimized for binary data. It is especially good at compressing arrays of similar data. For example, floats that fit a particular statistical distribution, integers from a restricted range, or pointers that all share the same alignment. It also works well on arrays of Structs with similar content.

Unlike most other compression libraries, Blosc is block-oriented, rather than stream-oriented. This works well when the entire dataset to be compressed/decompressed is available at once.

Example

let data: Vec<u32> = vec![1, 1, 2, 5, 8, 13, 21, 34, 55, 89, 144];
let ctx = Context::new();
let compressed = ctx.compress(&data[..]);
let decompressed = decompress(&compressed).unwrap();
assert_eq!(data, decompressed);

Structs

Buffer	An opaque Blosc-compressed buffer.
Context	Holds basic settings for compress operations.

Enums

Clevel	The desired compression level. Higher levels mean more compression.
Compressor	Compressor selection.
ShuffleMode	Controls Blosc's shuffle operation.

Functions

decompress	Decompress a blosc::Buffer into a newly allocated Vec
decompress_bytes⚠	Decompress arbitrary data into a newly allocated Vec
