Blosc

Rust bindings for the C-Blosc compression library.

The blosc crate provides Rusty bindings for C-Blosc, a compression library for binary data, especially numeric arrays.

Usage

# Cargo.toml
[dependencies]
blosc = "0.1"

extern crate blosc;

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

lib.rs:

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);
