Parameters data: A bytes-like object, data to be compressed. level_or_option: When it's an int object, it represents compression level. When it's a dict object, it contains advanced compression parameters. zstd_dict: A ZstdDict object, pre-trained dictionary for compression. )r r �FLUSH_FRAME��data�level_or_option� zstd_dict�comps r r r 3 s* � � �/�9�5�5�D��=�=��~�9�:�:�:r c �L � t ||� � }|� | � � S )aB Compress a block of data, return a bytes object. Use rich memory mode, it's faster than compress() in some cases, but allocates more memory. Compressing b'' will get an empty content frame (9 bytes or more).

Given a custom content as a basis for dictionary, and a set of samples, finalize dictionary by adding headers and statistics according to the zstd dictionary format. You may compose an effective dictionary content by hand, which is used as basis dictionary, and use some samples to finalize a dictionary. The basis dictionary can be a "raw content" dictionary, see is_raw parameter in ZstdDict.__init__ method. Parameters zstd_dict: A ZstdDict object, basis dictionary. samples: An iterable of samples, a sample is a bytes-like object represents a file. dict_size: The dictionary's maximum size, in bytes. level: The compression level expected to use in production. The statistics for each compression level differ, so tuning the dictionary for the compression level can help quite a bit. )r � � z�This function only available when the underlying zstd library's version is greater than or equal to v1.4.5, the current underlying zstd library's version is v%s.�/zstd_dict argument should be a ZstdDict object.r<
