huff-rs

Huffman encoding library.

This library has a HuffTree used for writing with HuffWriter and reading with HuffReader.

Example

Below is an example of encoding "hello world" with the string as the input data to the Huffman tree.

let tree = HuffBuilder::new()
    .add('h', 1)
    .add('e', 1)
    .add('l', 2)
    .add('o', 2)
    .add(' ', 1)
    .add('w', 1)
    .add('r', 1)
    .add('d', 1)
    .build().unwrap();

let stream = vec![];
let writer = HuffWriter(tree, &mut stream);

for c in "hello world".to_owned() {
    writer.write(c);
}
