class FallbackExecutor:
    """
    A class for executing tasks with a fallback mechanism in case of errors.

    This class provides a way to run tasks that might fail due to various reasons.
    In such cases, predefined fallback functions can be executed to recover from the error gracefully.

    Attributes:
        primary_function (Callable): The main function to execute. Raises an exception if it fails.
        fallback_functions (List[Callable]): List of functions to attempt in case the primary function fails.
        error_handler (Optional[Callable]): A function to handle the exception before attempting fallbacks.

    Methods:
        run: Executes the primary function or a fallback if the primary function raises an exception.
