Trait Implementations

impl AsRef<PyObject> for PyMapping<'_>

fn as_ref(&self) -> &PyObject

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> Clone for PyMapping<'a>

fn clone(&self) -> PyMapping<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> From<&'a PyObject> for PyMapping<'a>

fn from(obj: &'a PyObject) -> Self

Converts to this type from the input type.

impl Traverse for PyMapping<'_>

fn traverse(&self, tracer_fn: &mut TraverseFn<'_>)

impl traverse() with caution! Following those guideline so traverse doesn’t cause memory error!:

impl<'a> Copy for PyMapping<'a>
