def resource_method_info(self, method) -> tuple:
        """Return the (class) name of the resource and its type, which
        is associated with the provided method (function).

        Used by this class' decorators to determine the name of the
        instance which subclassed this class, e.g., `WorksCollection`,
        as well as passing a nice `enum` for determining if it's
        a collection or singleton resource.

        Arguments:
            method (function): Hopefully a method which belongs
                to an instance that inherited from this class.

        Raises:
            InvalidResourceName: If the function belongs to
                a resource class whose name neither ends in
                `Collection` nor `Singleton`.

        Returns:
            tuple[str, str]: Resource class name, resoure type.
