Function zstd_sys::ZSTD_createCDict

) -> *mut ZSTD_CDict

ZSTD_createCDict() : When compressing multiple messages / blocks with the same dictionary, it's recommended to load it just once. ZSTD_createCDict() will create a digested dictionary, ready to start future compression operations without startup delay. ZSTD_CDict can be created once and shared by multiple threads concurrently, since its usage is read-only. dictBuffer can be released after ZSTD_CDict creation, since its content is copied within CDict
