# chdlady-core

Core container library for MAME CHD (Compressed Hunks of Data) files.

This crate provides header parsing for CHD v3, v4, and v5, hunk map decoding, metadata read/write, SHA-1 integrity verification, and a full suite of compression and decompression codecs (zlib, LZMA, zstd, Huffman, FLAC, CD-optimized variants, and A/V Huffman). Parallel decompression and compression are supported via rayon.
