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* (see :term:`slotted classes` for potentially surprising behaviors) - *auto_exc=True* - *auto_detect=True* - *order=False* - *match_args=True* - 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``. cs2t| |  d  dS)NT) maybe_clsr rrrrrrrrrrrrrrZcollect_by_mrorrrr)r )clsr)rrrrrrrrrrrrrrrrr r2/tmp/pip-unpacked-wheel-9rkxrohn/attr/_next_gen.pydo_itRs.zdefine..do_itcsdtjfk}dkr"dkr"t|jD]$}|jtkr(|rBtdtjqNq(dk r`|Sz |dWStk r|dYSXdS)z Making this a wrapper ensures this code runs during class creation.
