Struct cpython::oldstyle::PyClass

pub struct PyClass(_);

Represents an old-style Python class.

Only available with Python 2.x.

Implementations

impl PyClass

pub fn is_subclass_of(&self, _py: Python<'_>, base: &PyClass) -> bool

Return true if self is a subclass of base.

pub fn create_instance<T>(
    &self,
    py: Python<'_>,
    args: T,
    kw: Option<&PyDict>
) -> PyResult<PyInstance> where
    T: ToPyObject<ObjectType = PyTuple>, 

Create a new instance of the class. The parameters args and kw are used as the positional and keyword parameters to the object’s constructor.

pub fn create_instance_raw(
    &self,
    py: Python<'_>,
    dict: &PyDict
) -> PyResult<PyInstance>

Create a new instance of a specific class without calling its constructor. The dict parameter will be used as the object’s dict.

Trait Implementations

impl<'s> FromPyObject<'s> for PyClass

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

Extracts Self from the source PyObject.

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

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

Extracts Self from the source PyObject.

impl PythonObject for PyClass

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 PyClass

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

Cast from PyObject to a concrete Python object type.

impl PythonObjectWithTypeObject for PyClass

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

Retrieves the type object for this Python object type.

impl ToPyObject for PyClass

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

type ObjectType = PyClass

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

Converts self into a Python object.

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

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.
