:param default: A value that is used if an ``attrs``-generated ``__init__``
is used and no value is passed while instantiating or the attribute is
excluded using ``init=False``.
If the value is an instance of :class:`Factory`, its callable will be
used to construct a new value (useful for mutable datatypes like lists
or dicts).
If a default is not set (or set manually to ``attr.NOTHING``), a value
*must* be supplied when instantiating; otherwise a :exc:`TypeError`
will be raised.
The default can also be set using decorator notation as shown below.
:type default: Any value.

``__init__`` methods after the instance has been initialized. They
receive the initialized instance, the :class:`Attribute`, and the
passed value.
The return value is *not* inspected so the validator has to throw an
exception itself.
If a ``list`` is passed, its items are treated as validators and must
all pass.
Validators can be globally disabled and re-enabled using
:func:`get_run_validators`.
The validator can also be set using decorator notation as shown below.

correct behavior according the Python spec. Setting this value to
anything else than ``None`` is *discouraged*.
:type hash: ``bool`` or ``None``
:param bool init: Include this attribute in the generated ``__init__``
method. It is possible to set this to ``False`` and set a default
value. In that case this attributed is unconditionally initialized
with the specified default value or factory.
:param callable convert: :func:`callable` that is called by
``attrs``-generated ``__init__`` methods to convert attribute's value
to the desired format. It is given the passed-in value, and the
returned value will be used as the new value of the attribute. The
value is converted before being passed to the validator, if any.

components. See :ref:`extending_metadata`.

r"""
A class decorator that adds `dunder
<https://wiki.python.org/moin/DunderAlias>`_\ -methods according to the
specified attributes using :func:`attr.ib` or the *these* argument.
:param these: A dictionary of name to :func:`attr.ib` mappings. This is
useful to avoid the definition of your attributes within the class body
because you can't (e.g. if you want to add ``__repr__`` methods to
Django models) or don't want to.
If *these* is not ``None``, ``attrs`` will *not* search the class body
for attributes.
:type these: :class:`dict` of :class:`str` to :func:`attr.ib`
:param str repr_ns: When using nested classes, there's no way in Python 2
to automatically detect that. Therefore it's possible to set the
namespace explicitly for a more meaningful ``repr`` output.
:param bool repr: Create a ``__repr__`` method with a human readable
represantation of ``attrs`` attributes..
:param bool str: Create a ``__str__`` method that is identical to
``__repr__``. This is usually not necessary except for
:class:`Exception`\ s.
:param bool cmp: Create ``__eq__``, ``__ne__``, ``__lt__``, ``__le__``,
``__gt__``, and ``__ge__`` methods that compare the class as if it were
a tuple of its ``attrs`` attributes. But the attributes are *only*
compared, if the type of both classes is *identical*!
:param hash: If ``None`` (default), the ``__hash__`` method is generated
according how *cmp* and *frozen* are set.
1. If *both* are True, ``attrs`` will generate a ``__hash__`` for you.
2. If *cmp* is True and *frozen* is False, ``__hash__`` will be set to
None, marking it unhashable (which it is).
3. If *cmp* is False, ``__hash__`` will be left untouched meaning the
``__hash__`` method of the superclass will be used (if superclass is
``object``, this means it will fall back to id-based hashing.).
Although not recommended, you can decide for yourself and force
``attrs`` to create one (e.g. if the class is immutable even though you
didn't freeze it programmatically) by passing ``True`` or not. Both of
these cases are rather special and should be used carefully.
See the `Python documentation \
<https://docs.python.org/3/reference/datamodel.html#object.__hash__>`_
and the `GitHub issue that led to the default behavior \
<https://github.com/python-attrs/attrs/issues/136>`_ for more details.
:type hash: ``bool`` or ``None``
:param bool init: Create a ``__init__`` method that initialiazes the
``attrs`` attributes. Leading underscores are stripped for the
argument name. If a ``__attrs_post_init__`` method exists on the
class, it will be called after the class is fully initialized.
:param bool slots: Create a slots_-style class that's more
memory-efficient. See :ref:`slots` for further ramifications.
:param bool frozen: Make instances immutable after initialization. If
someone attempts to modify a frozen instance,
:exc:`attr.exceptions.FrozenInstanceError` is raised.
Please note:
1. This is achieved by installing a custom ``__setattr__`` method
on your class so you can't implement an own one.
2. True immutability is impossible in Python.
3. This *does* have a minor a runtime performance :ref:`impact
<how-frozen>` when initializing new instances. In other words:
``__init__`` is slightly slower with ``frozen=True``.
4. If a class is frozen, you cannot modify ``self`` in
``__attrs_post_init__`` or a self-written ``__init__``. You can
circumvent that limitation by using
``object.__setattr__(self, "attribute_name", value)``.
