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 zThis 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<z'level argument should be an int object.r z9The samples are empty content, can't finalize dictionary.) r&r%NotImplementedErrorr3rr>r=r?r:r@rArrG) r.rBrClevelmsgrDrErFrGs r r r {s;*9$$GJVW"#&&& i * *KIJJJ i % %GEFFF eS ! !CABBBFK++ e75>>**** XXf  F VTUUU")"8"(+"+U44L L ! !!r ic0eZdZdZddZejfdZdS)ZstdDecompressReadercg} |t}|sn||3d|S)NTr )readrr?r@)selfrDr,s r readallzZstdDecompressReader.readallsU 99W%%D  MM$    xxr c|dkr|S|r|jrdS |jjrR|jt }|s0|jjrd|_|j|_ dStdnd}|j ||}|r|xjt|z c_|S)Nrr TzACompressed file ended before the end-of-stream marker was reached) rT_eof _decompressor needs_input_fprRr at_frame_edge_pos_sizeEOFErrorrr6)rSsizerawblockr,s r rRzZstdDecompressReader.reads !88<<>> ! ty 3 !- 8==)<==K)7K$( %)Y "s&(JKKK K%004@@D  SYY&  # r cH|tjkrn|tjkr |j|z}n}|tjkrK|jdkr5|tr |t|j|z}n"td |||jkr| n ||jz}|dkrC|tt|}|sn|t|z}|dkC|jS)NrzInvalid value for whence: {}) ioSEEK_SETSEEK_CURr\SEEK_ENDr]rR_32_KiBrAformat_rewindminr6)rSoffsetwhencer,s r seekzZstdDecompressReader.seeks R[  r{ " "Y'FF r{ " "zA~~ii((ii((Z&(FF;BB6JJKK K DI   LLNNNN di Fqjj99S&1122D  c$ii F qjj yr NrU)rrrrTrRrbrcrlr r r rPrPsR    :#%+r rPceZdZdZdddddZdZddZdZd Zdd Z dd Z d Z dZ ddZ ejfdZddZdZdZedZdZdZdZdS)r#a?A file object providing transparent zstd (de)compression.
