Struct cpython::PyLong

pub struct PyLong(_);

In Python 2.x, represents a Python long object. In Python 3.x, represents a Python int object. Both PyInt and PyLong refer to the same type on Python 3.x.

You can usually avoid directly working with this type by using ToPyObject and extract with the primitive Rust integer types.

Trait Implementations

impl PythonObject for PyLong

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 PyLong

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

Cast from PyObject to a concrete Python object type.

impl PythonObjectWithTypeObject for PyLong

fn type_object(py: Python) -> PyType

Retrieves the type object for this Python object type.

impl ToPyObject for PyLong

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

type ObjectType = PyLong

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

Converts self into a Python object.

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

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 PyLong

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

Extracts Self from the source PyObject.

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

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

Extracts Self from the source PyObject.
