class wtypes.python_types._NoType

class wtypes.python_types._ForwardSchema

Bases: wtypes.base._ContextMeta

A forward reference to an object, the object must exist in sys.modules.

Notes

Python types live on the __annotations__ attribute.

class wtypes.python_types.Forward

Create type using objects or forward references.

Examples

>>> assert Forward['builtins.range']() is range

class wtypes.python_types.Class

Bases: wtypes.python_types.Forward

Create type using objects or forward references.

Examples

>>> assert isinstance(range, Class['builtins.range'])

classmethod validate(cls, object)

class wtypes.python_types.Instance

Bases: wtypes.python_types.Forward

Create an instance of a type using objects or forward references.

Examples

>>> assert (Instance[range] + Args[10, 20])() == range(10, 20)
>>> assert (Instance['builtins.range'] + Args[10, 20])() == range(10, 20)
>>> assert isinstance(range(10), Instance['builtins.range'])

Deffered references.

>>> assert not isinstance(1, Instance['pandas.DataFrame'])
>>> assert 'pandas' not in __import__('sys').modules
