Crate hfmn 

hfmn is a library for huffman encoding and decoding of arbitrary symbols. It supports code lengths up to std::mem::size_of::<usize>() * 8 bits.

Nomenclature

• Symbol refers to your data, which can be of an arbitrary type
• Code refers to the prefix-free huffman code

Examples

use hfmn::CodeBook;

let data_to_encode = "lorem ipsum dolor sit amet";

let codebook = CodeBook::from_data(&data_to_encode).unwrap();

let encoded_data = codebook.encode_data(&data_to_encode).unwrap();
let more_encoded_data = codebook.encode_data(&"optimum allied restrooms");
