class FallbackExecutor:
    """
    A class for executing a function with fallback mechanisms in case of errors.
    
    Parameters:
        main_executor (Callable): The primary function to execute.
        error_handler (Optional[Callable]): The function to call if the main executor raises an exception. 
                                            It should accept the same arguments as `main_executor` and return the same type.
        retries (int, optional): Number of times to retry execution before giving up. Defaults to 3.

    Usage:
        def divide(a: float, b: float) -> float:
            return a / b

        # Fallback function for divide which returns 0 if division by zero occurs
        def safe_divide(a: float, b: float) -> float:
            if b == 0:
                return 0.0
            return a / b

                                    error_handler=safe_divide)
        
        result = executor.execute(10, 0)  # This will return 0 instead of raising an exception.

        Executes the main function with provided arguments.
