State-of-the-art lossless data compression in Go. The goal is to provide clean APIs and really fast implementation of common algorithms. It includes compression codecs (Run Length coding, Exp Golomb coding, Huffman, Range, LZ, ANS, Context Mixers, PAQ derivatives), bit stream manipulation, and transforms such as Burrows-Wheeler (BWT) and Move-To-Front, etc ...
Kanzi is the most versatile lossless data compressor in Go. However, it is not an implementation of usual compression formats (zip, Zstandard, LZMA, ...).
