class FallbackExecutor:
    """
    A class for executing functions with fallback mechanisms in case of errors.
    
    This implementation allows registering multiple fallback functions and will execute them based on error types.

    Args:
        primary_function (Callable): The main function to be executed.
        fallbacks (Dict[Exception, Callable], optional): A dictionary mapping exception classes to their corresponding
                                                          fallback functions. Defaults to an empty dictionary.
    
    Example Usage:

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

    >>> def safe_divide(a: float, b: float) -> Optional[float]:
    ...     try:
    ...         return divide(a, b)
    ...     except ZeroDivisionError as e:
    ...         print(f"Caught an error: {e}")
    ...         return None

    >>> fallbacks = {
    ...     ZeroDivisionError: lambda a, b: 0,
    ... }

    >>> executor = FallbackExecutor(primary_function=divide, fallbacks=fallbacks)
    >>> result = executor.execute(10.0, 2.0)  # Output will be 5.0
    >>> print(result)
    5.0

    >>> result = executor.execute(10.0, 0.0)  # Output will handle the ZeroDivisionError by returning a fallback value of 0
    >>> print(result)
    0
