Struct PyNone

pub struct PyNone(/* private fields */);

Represents the Python None object.

Values of this type are accessed via PyO3’s smart pointers, e.g. as Py<PyNone> or Bound<'py, PyNone>.

Implementations

impl PyNone

pub fn get_bound(py: Python<'_>) -> Borrowed<'_, '_, PyNone>

Returns the None object.

Trait Implementations

impl AsPyPointer for PyNone

fn as_ptr(&self) -> *mut PyObject

Gets the underlying FFI pointer, returns a borrowed pointer.

impl AsRef<PyAny> for PyNone

fn as_ref(&self) -> &PyAny

Converts this type into a shared reference of the (usually inferred) input type.

impl Deref for PyNone

type Target = PyAny

The resulting type after dereferencing.

fn deref(&self) -> &PyAny

Dereferences the value.

impl PyTypeInfo for PyNone

const NAME: &'static str = "NoneType"

Class name.

const MODULE: Option<&'static str> = None

Module name, if any.

fn type_object_raw(_py: Python<'_>) -> *mut PyTypeObject

Returns the PyTypeObject instance for this type.

fn is_type_of_bound(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of_bound(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.

fn type_object_bound(py: Python<'_>) -> Bound<'_, PyType>

Returns the safe abstraction over the type object.
