type ShapePlan *C.hb_shape_plan_t

ShapePlan holds a shaping plan.

Shape plans contain information about how HarfBuzz will shape a particular text segment, based on the segment's properties and the capabilities in the font face in use.

Shape plans can be queried about how shaping will perform, given a set of specific input parameters (script, language, direction, features, etc.).
