Member documentation
- windowLog – largest match distance: larger == more compression, more memory needed during decompression
- chainLog – fully searched segment: larger == more compression, slower, more memory (useless for fast)
- hashLog – dispatch table: larger == faster, more memory
- searchLog – nb of searches: larger == more compression, slower
- minMatch – match length searched: larger == faster decompression, sometimes less compression
- targetLength – acceptable match size for optimal parser (only): larger == more compression, slower
- strategy – see ZSTD_strategy definition
