Functions

ll_code

Convert a literal length value to its code. Ported from ZSTD_LLcode() in zstd_compress_internal.h.

ml_code

Convert a match length base (matchLength - 3) to its code. Ported from ZSTD_MLcode() in zstd_compress_internal.h.

off_code

Convert an offset value to its code (highest bit position + 1).
