Struct PyLease

pub struct PyLease<'a, T: PyObjectPayload> { /* 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<'a, T: PyObjectPayload + PyPayload> PyLease<'a, 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>>
