    A class for executing functions with fallback mechanisms.

    This class is designed to provide error handling capabilities,
    allowing a primary function to execute while providing alternative
    actions in case of errors or exceptions.
    
    Attributes:
        primary_function (Callable): The main function that will be executed.
        fallback_functions (list[Callable]): A list of functions that can be used as fallbacks if the primary function fails.

    Methods:
        run: Executes the primary function and handles any exceptions by executing fallbacks sequentially until success or no more fallbacks are available.
