Trait HasPyGilRef

pub unsafe trait HasPyGilRef {
    type AsRefTarget: PyNativeType;
}

Available on crate feature gil-refs only.

Specifies that this type has a “GIL-bound Reference” form.

This is expected to be deprecated in the near future, see https://github.com/PyO3/pyo3/issues/3382

Safety

• Py<Self>::as_ref will hand out references to Self::AsRefTarget.
• Self::AsRefTarget must have the same layout as UnsafeCell<ffi::PyAny>.

Required Associated Types
