## Types and Values

typedef | hb_shape_plan_t

## Includes

    #include <hb.h>

## Description

Shape plans are not used for shaping directly, but can be access to query certain information about how shaping will perform given a set of input parameters (script, language, direction, features, etc.) Most client would not need to deal with shape plans directly.
