```python
class FallbackExecutor:
    """
    A class for executing functions with fallback mechanisms in case of errors.

    This implementation includes a method `execute_with_fallback` which takes two callable objects: 
    the primary function and the fallback function. If an error occurs during the execution of the 
    primary function, the fallback function is called instead.
    
    Parameters:
        - primary_func (Callable): The primary function to be executed.
        - fallback_func (Callable): The fallback function to be used if an error occurs.

    Example Usage:

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

        def safe_divide(a: float, b: float) -> Union[float, str]:
            try:
                return divide(a, b)
            except ZeroDivisionError as e:
                print(f"Error: {e}")
                return "Division by zero is not allowed."

        def fallback_handler() -> str:
            return "Fallback: Performing safe operation..."

        executor = FallbackExecutor(safe_divide, fallback_handler)
        result = executor.execute_with_fallback(10.0, 2.0)  # Result will be 5.0
        print(result)

        result = executor.execute_with_fallback(10.0, 0.0)  # Result will be 'Fallback: Performing safe operation...'
        print(result)
