Struct cpython::PyRustObject

pub struct PyRustObject<T, B = PyObject> where T: 'static + Send, B: PythonBaseObject {
    // some fields omitted
}

A Python object that contains a rust value of type T, and is derived from base class B. Note that this type effectively acts like Rc<T>, except that the reference counting is done by the Python runtime.

Methods

impl<T, B> PyRustObject<T, B> where T: 'static + Send, B: PythonBaseObject

fn as_base(&self) -> &B

Gets a reference to this object, but of the base class type.

fn into_base(self) -> B

Gets a reference to this object, but of the base class type.

fn get<'a>(&'a self, _py: Python<'a>) -> &'a T

Gets a reference to the rust value stored in this Python object.

Trait Implementations

impl<T, B> ToPyObject for PyRustObject<T, B> where T: 'static + Send, B: PythonBaseObject

type ObjectType = PyObject

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

Converts self into a Python object.

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

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<T, B> PythonObject for PyRustObject<T, B> where T: 'static + Send, B: PythonBaseObject

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.
