huffman_coding

Small library for pure huffman coding in Rust.

This library exposes a reader for decoding encoded data and a writer for encoding data.

Documentation

Usage

First add this library as dependency to your cargo manifest

huffman_coding = "0.1.0"

Then, import the library at the start of your main/library

extern crate huffman_coding;

Finally you can use the exported structs as you please

use std::io::Write;
let pseudo_data = vec![0, 0, 1, 2, 2];
let tree = HuffmanTree::new(&pseudo_data[..]);

let mut vec = Vec::new();
{
    let mut writer = HuffmanWriter::new(&mut vec, &tree);
    assert!(writer.write(&[0, 0, 1, 1, 2, 2, 2, 2]).is_ok())
}

Binaries

There are two small example binaries, one for encoding a file, the other for decoding a file. As these require command line parsing, they are gated behind the feature flag bin. To build them, use cargo build --features "bin"
