It should start from the beginning of a frame, and needs to include at least the frame header (6 to 18 bytes). The returned FrameInfo object has two attributes. 'decompressed_size' is the size in bytes of the data in the frame when decompressed, or None when the decompressed size is unknown. 'dictionary_id' is an int in the range (0, 2**32). The special value 0 means that the dictionary ID was not recorded in the frame header, the frame may or may not need a dictionary to be decoded, and the ID of such a dictionary is not specified. )r_zstdr ) frame_buffers r)r r Gs e**<8 99r,c:[U[5(d%[U5Rn[ SU<S35e[ U5nSR U5n[ SU55nU(d [S5e[R"X4U5n[U5$)zReturn a ZstdDict representing a trained Zstandard dictionary. *samples* is an iterable of samples, where a sample is a bytes-like object representing a file. *dict_size* is the dictionary's maximum size, in bytes. z%dict_size must be an int object, not .r,c38# UHn[U5v M g7fNr.0samples r) train_dict..g>gFgz2samples contained no data; can't train dictionary.) isinstanceinttyper: TypeErrortuplejoin ValueErrorrArr)samples dict_sizeds_clschunks chunk_sizes dict_contents r)rrYs i % %i--?zKLLGnG XXg F>g>>K MNN##FCL L !!r,c[U[5(d [S5e[U[5(d [S5e[U[5(d [S5e[ U5nSR U5n[ SU55nU(d [ S5e[R"URUXRU5n[U5$)aReturn a ZstdDict representing a finalized Zstandard dictionary. Given a custom content as a basis for dictionary, and a set of samples, finalize *zstd_dict* by adding headers and statistics according to the Zstandard 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 may be a "raw content" dictionary. See *is_raw* in ZstdDict. *samples* is an iterable of samples, where a sample is a bytes-like object representing a file. *dict_size* is the dictionary's maximum size, in bytes. *level* is the expected compression level. The statistics for each compression level differ, so tuning the dictionary to the compression level can provide improvements. z/zstd_dict argument should be a ZstdDict object.z+dict_size argument should be an int object.z'level argument should be an int object.r,c38# UHn[U5v M g7frFrGrHs r)rK finalize_dict..rMrNz=The samples are empty content, can't finalize the dictionary.) rOrrRrPrSrTrUrAr r[) zstd_dictrVrWlevelrYrZr[s r)r r ns( i * *IJJ i % %EFF eS ! !ABBGnG XXg F>g>>K '( (&&y'='=v'2uFL L !!r,cR[XUS9nURU[RS9$)aReturn Zstandard compressed *data* as bytes. *level* is an int specifying the compression level to use, defaulting to COMPRESSION_LEVEL_DEFAULT ('3'). *options* is a dict object that contains advanced compression parameters.
