pub fn clone_py_object(obj: &Py<PyAny>) -> Py<PyAny>Expand description
Clones a Python object reference by attaching to the interpreter.
The result is a second strong reference to the same object, so this does not break a reference
cycle. When a Rust object holds a Py<T> whose Python object reaches back into Rust, cloning
adds another strong edge to that cycle rather than removing one.
Break such a back-reference with a Python weak reference (see upgrade_py_weakref) or an
explicit terminal release point that drops the strong reference during disposal.
