Trait Implementations

impl<'s> FromPyObject<'s> for &'s ValueError

fn extract(py: Python<'_>, obj: &'s PyObject) -> PyResult<&'s ValueError>

Extracts Self from the source PyObject.

impl<'s> FromPyObject<'s> for ValueError

fn extract(py: Python<'_>, obj: &'s PyObject) -> PyResult<ValueError>

Extracts Self from the source PyObject.

impl PythonObject for ValueError

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.

fn as_object(&self) -> &PyObject

Casts the Python object to PyObject.

fn into_object(self) -> PyObject

Casts the Python object to PyObject.

impl PythonObjectWithCheckedDowncast for ValueError

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

Cast from PyObject to a concrete Python object type.

impl PythonObjectWithTypeObject for ValueError

fn type_object(py: Python<'_>) -> PyType

Retrieves the type object for this Python object type.

impl ToPyObject for ValueError

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

type ObjectType = ValueError

fn to_py_object(&self, py: Python<'_>) -> ValueError

Converts self into a Python object.

fn into_py_object(self, _py: Python<'_>) -> ValueError

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.
