class FallbackExecutor:
    """
    A class for executing a primary function with fallbacks in case of errors.

    Parameters:
        - primary_func (Callable): The main function to execute.
        - fallback_funcs (Dict[Exception, Callable]): A dictionary mapping exceptions
          to their corresponding fallback functions. Each key must be an exception type,
          and the value is a callable that takes the same arguments as `primary_func`.

    Usage example:
    >>> 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

    >>> fallback_funcs = {
    ...     ZeroDivisionError: safe_divide
    ... }

    >>> executor = FallbackExecutor(primary_func=divide, fallback_funcs=fallback_funcs)
    >>> result = executor.execute(a=10.0, b=2.0)  # Normal execution
    >>> print(result)  # Output: 5.0

    >>> result = executor.execute(a=10.0, b=0.0)  # Fallback due to ZeroDivisionError
    >>> print(result)  # Output: Caught an error: division by zero
