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");
