Fields

windowLog: c_uint

< largest match distance : larger == more compression, more memory needed during decompression

chainLog: c_uint

< fully searched segment : larger == more compression, slower, more memory (useless for fast)

hashLog: c_uint

< dispatch table : larger == faster, more memory

searchLog: c_uint

< nb of searches : larger == more compression, slower

minMatch: c_uint

< match length searched : larger == faster decompression, sometimes less compression

targetLength: c_uint

< acceptable match size for optimal parser (only) : larger == more compression, slower

strategy: ZSTD_strategy

< see ZSTD_strategy definition above
