BZip3-rs

BZip3 compression for Rust.

BZip3 file structure:

[ magic number ([u8; 5]) | block size (i32) | block1 | block2 | blockN... ]

Structure of each block: [ new size (i32) | read size (i32) | data ]

Due to the naming from the original bzip3 library, new size indicates the data size after compression, and read size indicates the original data size.

Examples

use std::io::Read;
use bzip3::read::{Bz3Decoder, Bz3Encoder};

let data = "hello, world".as_bytes();
let block_size = 100 * 1024; // 100 kiB

let mut compressor = Bz3Encoder::new(data, block_size).unwrap();
let mut decompressor = Bz3Decoder::new(&mut compressor).unwrap();

let mut contents = String::new();
decompressor.read_to_string(&mut contents).unwrap();
assert_eq!(contents, "hello, world");
