Trait Implementations

impl ToPyObject for KeyError

Identity conversion: allows using existing PyObject instances where T: ToPyObject is expected.

type ObjectType = KeyError

fn to_py_object(&self, py: Python) -> KeyError

Converts self into a Python object.

fn into_py_object(self, _py: Python) -> KeyError

Converts self into a Python object.

fn with_borrowed_ptr<F, R>(&self, _py: Python, f: F) -> R where
    F: FnOnce(*mut PyObject) -> R, 

Converts self into a Python object and calls the specified closure on the native FFI pointer underlying the Python object.

impl<'source> FromPyObject<'source> for KeyError

fn extract(py: Python, obj: &'source PyObject) -> PyResult<KeyError>

Extracts Self from the source PyObject.

impl<'source> FromPyObject<'source> for &'source KeyError

fn extract(py: Python, obj: &'source PyObject) -> PyResult<&'source KeyError>

Extracts Self from the source PyObject.

impl PythonObject for KeyError

fn as_object(&self) -> &PyObject

Casts the Python object to PyObject.

fn into_object(self) -> PyObject

Casts the Python object to PyObject.

unsafe fn unchecked_downcast_from(obj: PyObject) -> Self

Unchecked downcast from PyObject to Self. Undefined behavior if the input object does not have the expected type.

unsafe fn unchecked_downcast_borrow_from<'a>(obj: &'a PyObject) -> &'a Self

Unchecked downcast from PyObject to Self. Undefined behavior if the input object does not have the expected type.

impl PythonObjectWithCheckedDowncast for KeyError

fn downcast_from<'p>(
    py: Python<'p>,
    obj: PyObject
) -> Result<KeyError, PythonObjectDowncastError<'p>>

Cast from PyObject to a concrete Python object type.

fn downcast_borrow_from<'a, 'p>(
    py: Python<'p>,
    obj: &'a PyObject
) -> Result<&'a KeyError, PythonObjectDowncastError<'p>>

Cast from PyObject to a concrete Python object type.

impl PythonObjectWithTypeObject for KeyError

fn type_object(py: Python) -> PyType

Retrieves the type object for this Python object type.
