}

Implements the PyTypeInfo trait for a native Python type.

Safety

• $typeobject must be a function that produces a valid *mut PyTypeObject
• $checkfunction must be a function that accepts arbitrary *mut PyObject and returns true / false according to whether the object is an instance of the type from $typeobject
