pub trait ToBorrowedObject: ToPyObject {
    fn with_borrowed_ptr<F, R>(&self, py: Python<'_>, f: F) -> R
        F: FnOnce(*mut PyObject) -> R
, { ... } }
Expand description

This trait has two implementations: The slow one is implemented for all ToPyObject and creates a new object using ToPyObject::to_object, while the fast one is only implemented for AsPyPointer (we know that every AsPyPointer is also ToPyObject) and uses AsPyPointer::as_ptr()

Provided methods

Converts self into a Python object and calls the specified closure on the native FFI pointer underlying the Python object.

May be more efficient than to_object because it does not need to touch any reference counts when the input object already is a Python object.
