        :param url: url of the resource pointed to (href of the link)
        :param comes_from: instance of HTMLPage where the link was found,
            or string.
        :param requires_python: String containing the `Requires-Python`
            metadata field, specified in PEP 345. This may be specified by
            a data-requires-python attribute in the HTML link tag, as
            described in PEP 503.
        :param yanked_reason: the reason the file has been yanked, if the
            file has been yanked, or None if the file hasn't been yanked.
            This is the value of the "data-yanked" attribute, if present, in
            a simple repository HTML link. If the file has been yanked but
            no reason was provided, this should be the empty string. See
            PEP 592 for more information and the specification.
        :param cache_link_parsing: A flag that is used elsewhere to determine
                                   whether resources retrieved from this link
                                   should be cached. PyPI index urls should
                                   generally have this set to False, for
                                   example.
