Please consider using `attrs.field` in new code (``attr.ib`` will *never* go away, though). :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 `attrs.Factory`, its callable will be used to construct a new value (useful for mutable data types like lists or dicts). If a default is not set (or set manually to `attrs.NOTHING`), a value *must* be supplied when instantiating; otherwise a `TypeError` will be raised. The default can also be set using decorator notation as shown below. .. seealso:: `defaults` :param callable factory: Syntactic sugar for ``default=attr.Factory(factory)``. :param validator: `callable` that is called by *attrs*-generated ``__init__`` methods after the instance has been initialized. They receive the initialized instance, the :func:`~attrs.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 `attrs.validators.get_disabled` / `attrs.validators.set_disabled`. The validator can also be set using decorator notation as shown below. .. seealso:: :ref:`validators` :type validator: `callable` or a `list` of `callable`\ s. :param repr: Include this attribute in the generated ``__repr__`` method. If ``True``, include the attribute; if ``False``, omit it. By default, the built-in ``repr()`` function is used. To override how the attribute value is formatted, pass a ``callable`` that takes a single value and returns a string. Note that the resulting string is used as-is, i.e. it will be used directly *instead* of calling ``repr()`` (the default). :type repr: a `bool` or a `callable` to use a custom function. :param eq: If ``True`` (default), include this attribute in the generated ``__eq__`` and ``__ne__`` methods that check two instances for equality. To override how the attribute value is compared, pass a ``callable`` that takes a single value and returns the value to be compared. .. seealso:: `comparison` :type eq: a `bool` or a `callable`. :param order: If ``True`` (default), include this attributes in the generated ``__lt__``, ``__le__``, ``__gt__`` and ``__ge__`` methods. To override how the attribute value is ordered, pass a ``callable`` that takes a single value and returns the value to be ordered. .. seealso:: `comparison` :type order: a `bool` or a `callable`. :param cmp: Setting *cmp* is equivalent to setting *eq* and *order* to the same value. Must not be mixed with *eq* or *order*. .. seealso:: `comparison` :type cmp: a `bool` or a `callable`. :param bool | None hash: Include this attribute in the generated ``__hash__`` method. If ``None`` (default), mirror *eq*'s value. This is the correct behavior according the Python spec. Setting this value to anything else than ``None`` is *discouraged*. .. seealso:: `hashing` :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. .. seealso:: `init` :param callable converter: `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. .. seealso:: :ref:`converters` :param dict | None metadata: An arbitrary mapping, to be used by third-party components. See `extending-metadata`. :param type: The type of the attribute. Nowadays, the preferred method to specify the type is using a variable annotation (see :pep:`526`). This argument is provided for backward compatibility. Regardless of the approach used, the type will be stored on ``Attribute.type``. Please note that *attrs* doesn't do anything with this metadata by itself. You can use it as part of your own code or for `static type checking <types>`. :param bool kw_only: Make this attribute keyword-only in the generated ``__init__`` (if ``init`` is ``False``, this parameter is ignored). :param on_setattr: Allows to overwrite the *on_setattr* setting from `attr.s`. If left `None`, the *on_setattr* value from `attr.s` is used. Set to `attrs.setters.NO_OP` to run **no** `setattr` hooks for this attribute -- regardless of the setting in `attr.s`. :type on_setattr: `callable`, or a list of callables, or `None`, or `attrs.setters.NO_OP` :param str | None alias: Override this attribute's parameter name in the generated ``__init__`` method. If left `None`, default to ``name`` stripped of leading underscores.

Please consider using `attrs.define` / `attrs.frozen` in new code (``attr.s`` will *never* go away, though). :param these: A dictionary of name to `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 and will *not* remove any attributes from it. The order is deduced from the order of the attributes inside *these*. :type these: `dict` of `str` to `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 auto_detect: Instead of setting the *init*, *repr*, *eq*, *order*, and *hash* arguments explicitly, assume they are set to ``True`` **unless any** of the involved methods for one of the arguments is implemented in the *current* class (i.e. it is *not* inherited from some base class). So for example by implementing ``__eq__`` on a class yourself, *attrs* will deduce ``eq=False`` and will create *neither* ``__eq__`` *nor* ``__ne__`` (but Python classes come with a sensible ``__ne__`` by default, so it *should* be enough to only implement ``__eq__`` in most cases). .. warning:: If you prevent *attrs* from creating the ordering methods for you (``order=False``, e.g. by implementing ``__le__``), it becomes *your* responsibility to make sure its ordering is sound. The best way is to use the `functools.total_ordering` decorator. Passing ``True`` or ``False`` to *init*, *repr*, *eq*, *order*, *cmp*, or *hash* overrides whatever *auto_detect* would determine. :param bool repr: Create a ``__repr__`` method with a human readable representation of *attrs* attributes.. :param bool str: Create a ``__str__`` method that is identical to ``__repr__``. This is usually not necessary except for `Exception`\ s. :param bool | None eq: If ``True`` or ``None`` (default), add ``__eq__`` and ``__ne__`` methods that check two instances for equality. They compare the instances as if they were tuples of their *attrs* attributes if and only if the types of both classes are *identical*! .. seealso:: `comparison` :param bool | None order: If ``True``, add ``__lt__``, ``__le__``, ``__gt__``, and ``__ge__`` methods that behave like *eq* above and allow instances to be ordered. If ``None`` (default) mirror value of *eq*. .. seealso:: `comparison` :param bool | None cmp: Setting *cmp* is equivalent to setting *eq* and *order* to the same value. Must not be mixed with *eq* or *order*. .. seealso:: `comparison` :param bool | None unsafe_hash: If ``None`` (default), the ``__hash__`` method is generated according how *eq* and *frozen* are set. 1. If *both* are True, *attrs* will generate a ``__hash__`` for you. 2. If *eq* is True and *frozen* is False, ``__hash__`` will be set to None, marking it unhashable (which it is). 3. If *eq* is False, ``__hash__`` will be left untouched meaning the ``__hash__`` method of the base class will be used (if base class 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. .. seealso:: - Our documentation on `hashing`, - Python's documentation on `object.__hash__`, - and the `GitHub issue that led to the default \ behavior <https://github.com/python-attrs/attrs/issues/136>`_ for more details. :param bool | None hash: Alias for *unsafe_hash*. *unsafe_hash* takes precedence. :param bool init: Create a ``__init__`` method that initializes the *attrs* attributes. Leading underscores are stripped for the argument name. If a ``__attrs_pre_init__`` method exists on the class, it will be called before the class is initialized. If a ``__attrs_post_init__`` method exists on the class, it will be called after the class is fully initialized. If ``init`` is ``False``, an ``__attrs_init__`` method will be injected instead. This allows you to define a custom ``__init__`` method that can do pre-init work such as ``super().__init__()``, and then call ``__attrs_init__()`` and ``__attrs_post_init__()``. .. seealso:: `init` :param bool slots: Create a :term:`slotted class <slotted classes>` that's more memory-efficient. Slotted classes are generally superior to the default dict classes, but have some gotchas you should know about, so we encourage you to read the :term:`glossary entry <slotted classes>`. :param bool frozen: Make instances immutable after initialization. If someone attempts to modify a frozen instance, `attrs.exceptions.FrozenInstanceError` is raised. .. note:: 1. This is achieved by installing a custom ``__setattr__`` method on your class, so you can't implement your own. 2. True immutability is impossible in Python. 3. This *does* have a minor a runtime performance `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)``. 5. Subclasses of a frozen class are frozen too. :param bool weakref_slot: Make instances weak-referenceable. This has no effect unless ``slots`` is also enabled. :param bool auto_attribs: If ``True``, collect :pep:`526`-annotated attributes from the class body. In this case, you **must** annotate every field. If *attrs* encounters a field that is set to an `attr.ib` but lacks a type annotation, an `attr.exceptions.UnannotatedAttributeError` is raised. Use ``field_name: typing.Any = attr.ib(...)`` if you don't want to set a type. If you assign a value to those attributes (e.g. ``x: int = 42``), that value becomes the default value like if it were passed using ``attr.ib(default=42)``. Passing an instance of `attrs.Factory` also works as expected in most cases (see warning below). Attributes annotated as `typing.ClassVar`, and attributes that are neither annotated nor set to an `attr.ib` are **ignored**. .. warning:: For features that use the attribute name to create decorators (e.g. :ref:`validators <validators>`), you still *must* assign `attr.ib` to them. Otherwise Python will either not find the name or try to use the default value to call e.g. ``validator`` on it. These errors can be quite confusing and probably the most common bug report on our bug tracker. :param bool kw_only: Make all attributes keyword-only in the generated ``__init__`` (if ``init`` is ``False``, this parameter is ignored). :param bool cache_hash: Ensure that the object's hash code is computed only once and stored on the object. If this is set to ``True``, hashing must be either explicitly or implicitly enabled for this class. If the hash code is cached, avoid any reassignments of fields involved in hash code computation or mutations of the objects those fields point to after object creation. If such changes occur, the behavior of the object's hash code is undefined. :param bool auto_exc: If the class subclasses `BaseException` (which implicitly includes any subclass of any exception), the following happens to behave like a well-behaved Python exceptions class: - the values for *eq*, *order*, and *hash* are ignored and the instances compare and hash by the instance's ids (N.B. *attrs* will *not* remove existing implementations of ``__hash__`` or the equality methods. It just won't add own ones.), - all attributes that are either passed into ``__init__`` or have a default value are additionally available as a tuple in the ``args`` attribute, - the value of *str* is ignored leaving ``__str__`` to base classes. :param bool collect_by_mro: Setting this to `True` fixes the way *attrs* collects attributes from base classes. The default behavior is incorrect in certain cases of multiple inheritance. It should be on by default but is kept off for backward-compatibility. .. seealso:: Issue `#428 <https://github.com/python-attrs/attrs/issues/428>`_ :param bool | None getstate_setstate: .. note:: This is usually only interesting for slotted classes and you should probably just set *auto_detect* to `True`. If `True`, ``__getstate__`` and ``__setstate__`` are generated and attached to the class. This is necessary for slotted classes to be pickleable. If left `None`, it's `True` by default for slotted classes and ``False`` for dict classes. If *auto_detect* is `True`, and *getstate_setstate* is left `None`, and **either** ``__getstate__`` or ``__setstate__`` is detected directly on the class (i.e. not inherited), it is set to `False` (this is usually what you want). :param on_setattr: A callable that is run whenever the user attempts to set an attribute (either by assignment like ``i.x = 42`` or by using `setattr` like ``setattr(i, "x", 42)``). It receives the same arguments as validators: the instance, the attribute that is being modified, and the new value. If no exception is raised, the attribute is set to the return value of the callable. If a list of callables is passed, they're automatically wrapped in an `attrs.setters.pipe`. :type on_setattr: `callable`, or a list of callables, or `None`, or `attrs.setters.NO_OP` :param callable | None field_transformer: A function that is called with the original class object and all fields right before *attrs* finalizes the class. You can use this, e.g., to automatically add converters or validators to fields based on their types. .. seealso:: `transform-fields` :param bool match_args: If `True` (default), set ``__match_args__`` on the class to support :pep:`634` (Structural Pattern Matching). It is a tuple of all non-keyword-only ``__init__`` parameter names on Python 3.10 and later.

The class has *all* arguments of `attr.ib` (except for ``factory`` which is only syntactic sugar for ``default=Factory(...)`` plus the following: - ``name`` (`str`): The name of the attribute. - ``alias`` (`str`): The __init__ parameter name of the attribute, after any explicit overrides and default private-attribute-name handling. - ``inherited`` (`bool`): Whether or not that attribute has been inherited from a base class. - ``eq_key`` and ``order_key`` (`typing.Callable` or `None`): The callables that are used for comparing and ordering objects by this attribute, respectively. These are set by passing a callable to `attr.ib`'s ``eq``, ``order``, or ``cmp`` arguments. See also :ref:`comparison customization <custom-comparison>`. Instances of this class are frequently used for introspection purposes like: - `fields` returns a tuple of them. - Validators get them passed as the first argument. - The :ref:`field transformer <transform-fields>` hook receives a list of them. - The ``alias`` property exposes the __init__ parameter name of the field, with any overrides and default private-attribute handling applied. .. versionadded:: 20.1.0 *inherited* .. versionadded:: 20.1.0 *on_setattr* .. versionchanged:: 20.2.0 *inherited* is not taken into account for equality checks and hashing anymore. .. versionadded:: 21.1.0 *eq_key* and *order_key* .. versionadded:: 22.2.0 *alias* For the full version history of the fields, see `attr.ib`. )r^ r. r/ r0 r7 r8 r9 r: r2 r3 r5 r+ r4 r6 r r; r< Nc t ||xs | |xs |d \ } }}}t j | } |d| |d| |d| |d| |d| |d| |d| |d | |d | |d | |d | |d | r t j t | nt |d| |d| |d| |d| |d| y )NTr^ r. r/ r0 r7 r8 r9 r: r2 r3 r4 r5 r+ r6 r r; r< )r= r r typesMappingProxyTyper _empty_metadata_singleton)r r^ r. r/ r0 r1 r2 r3 r r5 r+ r4 r6 r7 r8 r9 r: r; r< bound_setattrs r r zAttribute.__init__* s * (B 2y 1E4( $FE9 %,,T2 fd#i)k9-fd#dB h'gu%k9-fd#fd#k9- &&tH~6. fd#i)k9-lJ/gu%r c t r' r r s r r zAttribute.__setattr__a s !##r c | |j }n|j d}t | t j D ci c] }|dvr |t || }} | d||j |j |d dd|S c c}w )Nz8Type annotation and type argument cannot both be present)r^ r/ r. r+ r F)r^ r/ r. r+ r1 r r )r+ r? r r& r _validator_default)r r^ r r+ rI r: inst_dicts r r z Attribute.from_counting_attrd s <77D WW LC S/ !
