Struct
PangoOT.RulesetDescription
Description [src]
struct PangoOTRulesetDescription {
PangoScript script;
PangoLanguage* language;
const PangoOTFeatureMap* static_gsub_features;
guint n_static_gsub_features;
const PangoOTFeatureMap* static_gpos_features;

const PangoOTFeatureMap* other_features;
guint n_other_features;
}
The PangoOTRuleset
structure holds all the information needed
to build a complete PangoOTRuleset
from an OpenType font.
The main use of this struct is to act as the key for a per-font
hash of rulesets. The user populates a ruleset description and
gets the ruleset using pango_ot_ruleset_get_for_description()
or create a new one using pango_ot_ruleset_new_from_description()
.
