fast, whole-buffer DEFLATE-based compression and decompression
The supported formats are:
* DEFLATE (raw) * zlib (a.k.a. DEFLATE with a zlib wrapper) * gzip (a.k.a. DEFLATE with a gzip wrapper)
libdeflate is heavily optimized. It is significantly faster than the zlib library, both for compression and decompression, and especially on x86 processors. In addition, libdeflate provides optional high compression modes that provide a better compression ratio than the zlib's "level 9".
