   .. method:: equal(desc2: ~gi.repository.PangoOT.RulesetDescription) -> bool

      Compares two ruleset descriptions for equality.

      Two ruleset descriptions are considered equal if the rulesets
      they describe are provably identical. This means that their
      script, language, and all feature sets should be equal.

      For static feature sets, the array addresses are compared directly,
      while for other features, the list of features is compared one by
      one.(Two ruleset descriptions may result in identical rulesets
      being created, but still compare :const:`False`.)

      :param desc2: a ruleset description





   .. method:: free() -> None

      Frees a ruleset description allocated by
      :func:`~gi.repository.PangoOT.RulesetDescription.copy`.



      .. versionadded:: 1.18








   .. method:: hash() -> int

      Computes a hash of a ``PangoOTRulesetDescription`` structure suitable
      to be used, for example, as an argument to :func:`~gi.repository.GLib.HashTable.new`.

   .. attribute:: language

      A ``PangoLanguage``







   .. attribute:: n_other_features

      Length of ``other_features``, or 0.







   .. attribute:: n_static_gpos_features

      Length of ``static_gpos_features``, or 0.







   .. attribute:: n_static_gsub_features

      Length of ``static_gsub_features``, or 0.







   .. attribute:: other_features

      Map of extra features to add to both
      GSUB and GPOS. Unlike the static maps, this pointer need not
      live beyond the life of function calls taking this struct.







   .. attribute:: script

      A ``PangoScript``







   .. attribute:: static_gpos_features

      Static map of GPOS features







   .. attribute:: static_gsub_features

      Static map of GSUB features
