docs: Formatting function for scalar values.
  
          This is used in the default '__repr__'. The returned formatting
          function receives instances of your scalar type.
  
          Parameters
          ----------
          boxed: bool, default False
              An indicated for whether or not your array is being printed
              within a Series, DataFrame, or Index (True), or just by
              itself (False). This may be useful if you want scalar values
              to appear differently within a Series versus on its own (e.g.
              quoted or not).
  
          Returns
          -------
          Callable[[Any], str]
              A callable that gets instances of the scalar type and
              returns a string. By default, :func:`repr` is used
              when ``boxed=False`` and :func:`str` is used when
              ``boxed=True``.
