class FallbackExecutor:
    """
    A class that provides a mechanism for executing tasks with limited error recovery.
    
    This class allows you to define multiple fallback strategies in case an initial 
    execution of the task fails. It supports retrying tasks and applying different 
    handlers for success or failure states.

    Args:
        primary_executor (Callable): The main function to be executed.
        retries (int, optional): Number of times to attempt executing the primary executor before giving up. Defaults to 3.
        success_handler (Optional[Callable[[Any], None]]): A callback function that gets called on successful execution.
        failure_handler (Optional[Callable[[Exception], None]]): A callback function that handles errors.

    Attributes:
        retries (int): Number of retry attempts for the primary task.
        success_handler (Optional[Callable[[Any], None]]): Callback for handling successes.
        failure_handler (Optional[Callable[[Exception], None]]): Callback for handling failures.
