Struct PyLease 

pub struct PyLease<'a, T: PyPayload> { /* private fields */ }

A borrow of a reference to a Python object. This avoids having clone the PyRef<T>/ PyObjectRef, which isn’t that cheap as that increments the atomic reference counter.

Implementations

impl<T: PyPayload> PyLease<'_, T>

pub fn into_owned(self) -> PyRef<T>

Methods from Deref<Target = Py<T>>

pub fn downgrade( &self, callback: Option<PyObjectRef>, vm: &VirtualMachine, ) -> PyResult<PyWeakRef<T>>

pub fn payload(&self) -> &T

pub fn to_base(&self) -> &Py<T::Base>

Converts &Py<T> to &Py<T::Base>.

pub fn upcast_ref<U: PyPayload + StaticType>(&self) -> &Py<U>

where T: StaticType,

Converts &Py<T> to &Py<U> where U is an ancestor type.
