Effective class properties as derived from parameters to `attr.s()` or
`define()` decorators.
This is the same data structure that *attrs* uses internally to decide how
to construct the final class.
Warning:
This feature is currently **experimental** and is not covered by our
strict backwards-compatibility guarantees.
Attributes:
is_exception (bool):
Whether the class is treated as an exception class.
is_slotted (bool):
Whether the class is `slotted <slotted classes>`.
has_weakref_slot (bool):
Whether the class has a slot for weak references.
is_frozen (bool):
Whether the class is frozen.
kw_only (KeywordOnly):
Whether / how the class enforces keyword-only arguments on the
``__init__`` method.
collected_fields_by_mro (bool):
Whether the class fields were collected by method resolution order.
That is, correctly but unlike `dataclasses`.
added_init (bool):
Whether the class has an *attrs*-generated ``__init__`` method.
added_repr (bool):
Whether the class has an *attrs*-generated ``__repr__`` method.
added_eq (bool):
Whether the class has *attrs*-generated equality methods.
added_ordering (bool):
Whether the class has *attrs*-generated ordering methods.
hashability (Hashability): How `hashable <hashing>` the class is.
added_match_args (bool):
Whether the class supports positional `match <match>` over its
fields.
added_str (bool):
Whether the class has an *attrs*-generated ``__str__`` method.
added_pickling (bool):
Whether the class has *attrs*-generated ``__getstate__`` and
``__setstate__`` methods for `pickle`.
on_setattr_hook (Callable[[Any, Attribute[Any], Any], Any] | None):
The class's ``__setattr__`` hook.
field_transformer (Callable[[Attribute[Any]], Attribute[Any]] | None):
The class's `field transformers <transform-fields>`.
