Universal.Common.IO.Compression

Class library for compression codecs not covered by System.IO.Compression: LZ4, LZMA (classic and Unity-header variants), and Zstandard. All from scratch, with no third-party package dependencies.

Each algorithm implements ICompressionAlgorithm (self-describing formats - Compress/Decompress need nothing but the data itself) or ISizedCompressionAlgorithm (raw LZ4 block format, whose decoder needs the original uncompressed size supplied separately, since the format carries no length or end marker of its own).

Quickstart

// LZ4 (ISizedCompressionAlgorithm - raw block format needs the original size to decompress)
Lz4CompressionAlgorithm lz4 = new Lz4CompressionAlgorithm();
byte[] compressed = lz4.Compress(data);
byte[] restored = lz4.Decompress(compressed, data.Length);

// LZMA, Zstandard, Deflate, Gzip (ICompressionAlgorithm - self-describing)
LzmaCompressionAlgorithm lzma = new LzmaCompressionAlgorithm();
byte[] compressed = lzma.Compress(data);
byte[] restored = lzma.Decompress(compressed);

ZstdCompressionAlgorithm zstd = new ZstdCompressionAlgorithm();
byte[] restored2 = zstd.Decompress(zstdCompressedBytes); // full decoder: raw/RLE/Huffman/FSE blocks alike

Status

  • LZ4, LZMA (+ Unity's own header variant): full encode and decode, verified byte-for-byte in both directions against independent real-world implementations (lz4js, Python's lzma module).
  • Zstandard: full decoder (frame/block parsing, FSE with predefined or custom tables, Huffman-coded literals, sequence execution) - verified against real Zstandard-compressed data, including actual Figma-exported .fig files. The encoder currently emits valid, standards-compliant frames using Raw/RLE blocks only (real data any conforming decoder reads correctly, just not entropy-coded) - full FSE/Huffman encoding is its own follow-up.

Initial release. LZ4 and LZMA (+ Unity's own LZMA header variant): full
encode/decode, verified byte-for-byte in both directions against independent reference implementations
(lz4js, Python's lzma module). Zstandard: full decoder (frame/block parsing, FSE with predefined or
custom tables, Huffman-coded literals, sequence execution), verified against real Zstandard-compressed
data including actual Figma-exported .fig files; the encoder currently emits valid standards-compliant
frames using Raw/RLE blocks only (correct, just not entropy-coded) - full FSE/Huffman encoding is a
follow-up. Also includes thin wrappers around System.IO.Compression's own Deflate/Gzip.
