    A class that provides a fallback mechanism for function execution.

    Attributes:
        primary_func (Callable): The main function to be executed.
        fallback_func (Optional[Callable]): The function to be used as a fallback in case of exceptions.
        recovery_mode (bool): A flag indicating whether error recovery is active or not.
    
    Methods:
        execute: Attempts to execute the primary function, falls back to the secondary if an exception occurs.
