docs: def unwrap_or(self, default: U) -> Union[T, U]:
          """
          Returns the contained value or ``default``.
  
          Args:
              default: The default value.
  
          Returns:
              The contained value if the :py:class:`Option` is ``Some``,
              otherwise ``default``.
  
          Notes:
              If you wish to use a result of a function call as the default,
              it is recommnded to use :py:meth:`unwrap_or_else` instead.
  
          Examples:
              >>> Some(0).unwrap_or(3)
              0
              >>> NONE.unwrap_or(0)
              0
