Description [src]
final class PangoOT.Ruleset : GObject.Object

/* No available fields */
}The PangoOTRuleset structure holds a set of features selected
from the tables in an OpenType font.
A feature is an operation such as adjusting glyph positioning that should be applied to a text feature such as a certain type of accent.
A PangoOTRuleset is created with pango_ot_ruleset_new(),
features are added to it with pango_ot_ruleset_add_feature(),
then it is applied to a PangoGlyphString with
pango_ot_ruleset_position().
