Struct pyo3::pycell::PyRefMut

pub struct PyRefMut<'p, T: PyClass> { /* fields omitted */ }

Wraps a mutable borrowed reference to a value in a PyCell<T>.

See the PyCell and PyRef documentations for more.

Implementations

impl<'p, T: PyClass> PyRefMut<'p, T>

pub fn py(&self) -> Python<'_>

Returns Python token. This function is safe since PyRefMut has the same lifetime as a GILGuard.

impl<'p, T, U> PyRefMut<'p, T> where
    T: PyClass + PyTypeInfo<BaseType = U, BaseLayout = PyCellInner<U>>,
    U: PyClass, 

pub fn into_super(self) -> PyRefMut<'p, U>

Get PyRef<T::BaseType>. See PyRef::into_super for more.

Trait Implementations

impl<'p, T, U> AsMut<U> for PyRefMut<'p, T> where
    T: PyClass + PyTypeInfo<BaseType = U, BaseLayout = PyCellInner<U>>,

fn as_mut(&mut self) -> &mut T::BaseType

Performs the conversion.

impl<'a, T: PyClass> AsPyPointer for PyRefMut<'a, T>

fn as_ptr(&self) -> *mut PyObject

impl<'p, T, U> AsRef<U> for PyRefMut<'p, T> where
