Differences to the classic `attr.s` that it uses underneath: - Automatically detect whether or not *auto_attribs* should be `True` (c.f. *auto_attribs* parameter). - If *frozen* is `False`, run converters and validators when setting an attribute by default. - *slots=True* .. caution:: Usually this has only upsides and few visible effects in everyday programming. But it *can* lead to some suprising behaviors, so please make sure to read :term:`slotted classes`. - *auto_exc=True* - *auto_detect=True* - *order=False* - Some options that were only relevant on Python 2 or were kept around for backwards-compatibility have been removed. Please note that these are all defaults and you can change them as you wish. :param Optional[bool] auto_attribs: If set to `True` or `False`, it behaves exactly like `attr.s`. If left `None`, `attr.s` will try to guess: 1. If any attributes are annotated and no unannotated `attrs.fields`\ s are found, it assumes *auto_attribs=True*. 2. Otherwise it assumes *auto_attribs=False* and tries to collect `attrs.fields`\ s. For now, please refer to `attr.s` for the rest of the parameters. .. versionadded:: 20.1.0 .. versionchanged:: 21.3.0 Converters are also run ``on_setattr``. ctdid|ddd d dddd d |d d d ddddddd dd S)N maybe_clsrrrrrrrrrrrrrrrcollect_by_mroTrrrr )r )clsrrrrrrrrrrrr rrrrrrrs E/usr/lib/python3/dist-packages/mercurial/thirdparty/attr/_next_gen.pydo_itzdefine..do_itVs           &  &  "    $!
