Optionally recurse into other ``attrs``-decorated classes. :param inst: Instance of an ``attrs``-decorated class. :param bool recurse: Recurse into classes that are also ``attrs``-decorated. :param callable filter: A callable whose return code determines whether an attribute or element is included (``True``) or dropped (``False``). Is called with the :class:`attr.Attribute` as the first argument and the value as the second argument. :param callable dict_factory: A callable to produce dictionaries from. For example, to produce ordered dictionaries instead of normal Python dictionaries, pass in ``collections.OrderedDict``. :param bool retain_collection_types: Do not convert to ``list`` when encountering an attribute whose type is ``tuple`` or ``set``.
