Implementation of functionality for PyType.

These methods are defined for the Bound<'py, PyType> smart pointer, so to use method call syntax these methods are separated into a trait, because stable Rust does not yet support arbitrary_self_types.

Required Methods

fn as_type_ptr(&self) -> *mut PyTypeObject

Retrieves the underlying FFI pointer associated with this Python object.

fn name(&self) -> Result<Bound<'py, PyString>, PyErr>

Gets the name of the PyType. Equivalent to self.__name__ in Python.

fn qualname(&self) -> Result<Bound<'py, PyString>, PyErr>

Gets the qualified name of the PyType. Equivalent to self.__qualname__ in Python.

fn module(&self) -> Result<Bound<'py, PyString>, PyErr>

Gets the name of the module defining the PyType.

fn fully_qualified_name(&self) -> Result<Bound<'py, PyString>, PyErr>

Gets the fully qualified name of the PyType.

fn is_subclass(&self, other: &Bound<'_, PyAny>) -> Result<bool, PyErr>

Checks whether self is a subclass of other.

Equivalent to the Python expression issubclass(self, other).

fn is_subclass_of<T>(&self) -> Result<bool, PyErr>

where T: PyTypeInfo,

Checks whether self is a subclass of type T.

Equivalent to the Python expression issubclass(self, T), if the type T is known at compile time.

fn mro(&self) -> Bound<'py, PyTuple>

Return the method resolution order for this type.

Equivalent to the Python expression self.__mro__.

fn bases(&self) -> Bound<'py, PyTuple>

Return Python bases

Equivalent to the Python expression self.__bases__.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
