Some specifier semantics imply boundaries between real versions: ``<=1.0`` includes ``1.0+local`` and ``>1.0`` excludes ``1.0.post0``. No real :class:`Version` falls on those boundaries, so this class creates values that sort between the real versions on either side. Two kinds exist, shown relative to a base version V:: V < V+local < AFTER_LOCALS(V) < V.post0 < AFTER_POSTS(V) ``AFTER_LOCALS`` sits after V and every V+local, but before V.post0. Upper bound of ``<=V``, ``==V``, ``!=V``. ``AFTER_POSTS`` sits after every V.postN, but before the next release segment. Lower bound of ``>V`` (final or pre-release V) to exclude post-releases per PEP 440. )_kind_trimmed_releaseversionrr1None)r=kindrcCs||_||_t|j|_dSr)r=r;r0r.r<)selfr=r?rrr__init__qsz_BoundaryVersion.__init__r(otherrcCsl|j}|j|jkr.t|j|jkr.|j|jks2dS|jtjkrV|j |j koT|j |j kS|j |j kpj|j duS)z6Is ``other`` a version that this boundary sorts above?FN) r=epochr0r.r<r'r;r1r8postdev)r@rCvrrr _is_familyvs   z_BoundaryVersion._is_familyrcCs&t|tr"|j|jko |j|jkStSr)r"r:r=r;NotImplementedr@rCrrr__eq__s z_BoundaryVersion.__eq__z_BoundaryVersion | VersioncCsHt|tr2|j|jkr"|j|jkS|jj|jjkS|| oF|j|kSr)r"r:r=r;valuerHrJrrr__lt__s    z_BoundaryVersion.__lt__intrcCst|j|jfSr)hashr=r;r@rrr__hash__sz_BoundaryVersion.__hash__r%cCs |jjd|jd|jjdS)N(z, )) __class__r2r=r;namerPrrr__repr__sz_BoundaryVersion.__repr__N) r2r3r4r5 __slots__rArHrKrMrQrVrrrrr:Ysr:c@sbeZdZdZdZddddddZd dd d d Zddd d dZddddZddddZ dS) _LowerBoundzLower bound of a version range.

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. )_canonicalized_has_arbitrary_is_unsatisfiabler _resolved_ops_specsrNzstr | Iterable[Specifier]rr>) specifiersrrcCst|tr:dd|dD}ttt||_d|v|_n t||_tdd|jD|_t |jdk|_ d|_ ||_ d|_ dS) aInitialize a SpecifierSet instance. :param specifiers: The string representation of a specifier or a comma-separated list of specifiers which will be parsed and normalized before use.
