WebThere are two main types of entropy coders, Huffman and arithmetic. Huffman’s big advantage is speed, while arithmetic coding gives better compression. Deflate chose to use Huffman, and even today, it’s a good tradeoff in speed vs compression. But before we implement Huffman, we need to be able to read and write bits, not bytes. WebHuffman codes are intuitive and in many cases optimal ways of encoding data losslessly. This post covers an implementation of simple huffman codes in Rust. Feel free to checkout the code. idea.
