Parse a given requirement string into its parts, such as name, specifier, URL, and extras. Raises InvalidRequirement on a badly-formed requirement string. Instances are safe to serialize with :mod:`pickle`. They use a stable format so the same pickle can be loaded in future packaging releases. .. versionchanged:: 26.2 Added a stable pickle format. Pickles created with packaging 26.2+ can be unpickled with future releases. Backward compatibility with pickles from packaging < 26.2 is supported but may be removed in a future release. strNone)requirement_stringrc Csz t|}Wn0tk r<}ztt||W5d}~XYnX|j|_|jpNd|_t|jp\g|_t|j |_ d|_ |j dk rt t |_ t |j |j _dSr)_parse_requirementrr rnameurlsetextrasr specifiermarkerr__new__r_markers)selfrparsederrr__init__5s      zRequirement.__init__z Iterator[str])rrccst|V|jr*dt|j}d|dV|jr) __class__rrr/rrr__repr__qszRequirement.__repr__intcCstt|t|jSr)hashtupler.r rr/rrr__hash__tszRequirement.__hash__bool)otherrcCsRt|tstSt|jt|jkoP|j|jkoP|j|jkoP|j|jkoP|j|jkSr) r3r NotImplementedr rrr rr!)r$rFrrr__eq__ws     zRequirement.__eq__N) rrrrr'r.r0r:r<r@rDrHrrrrr sN) __future__rtypingr_parserrr _tokenizerrmarkersrr specifiersr utilsr rr ValueErrorr r rrrrs
