Returns a tuple such that tuples sorting as greater using Python's default comparison operator are more preferred. The preference is as follows: First and foremost, candidates with allowed (matching) hashes are always preferred over candidates without matching hashes. This is because e.g. if the only candidate with an allowed hash is yanked, we still want to use that candidate. Second, excepting hash considerations, candidates that have been yanked (in the sense of PEP 592) are always less preferred than candidates that haven't been yanked. Then: If not finding wheels, they are sorted by version only. If finding wheels, then the sort order is by version, then: 1. existing installs 2. wheels ordered via Wheel.support_index_min(self._supported_tags) 3. source archives If prefer_binary was set, then all wheels are sorted above sources. Note: it was considered to embed this logic into the Link comparison operators, but then different sdist links with the same version, would have to be considered equal i sB {} is not a supported wheel for this platform.
