    A class for executing functions with fallback mechanisms in case of errors.

        primary_executor (Callable[..., Any]): The main function to be executed.
        secondary_executor (Callable[..., Any], optional): The fallback function to be used if the primary fails. Defaults to None.
        max_attempts (int, optional): Maximum number of attempts before giving up. Defaults to 3.
