hb_unicode_compose_func_t typedef

hb_unicode_compose_func_t = Pointer<NativeFunction<hb_unicode_compose_func_tFunction>>

hb_unicode_compose_func_t: @ufuncs: A Unicode-functions structure @a: The first code point to compose @b: The second code point to compose @ab: (out): The composed code point @user_data: user data pointer passed by the caller

A virtual method for the #hb_unicode_funcs_t structure.

This method should compose a sequence of two input Unicode code points by canonical equivalence, returning the composed code point in a #hb_codepoint_t output parameter (if successful). The method must return an #hb_bool_t indicating the success of the composition.

Return value: true is @a,@b composed, false otherwise

Implementation

typedef hb_unicode_compose_func_t =
    ffi.Pointer<ffi.NativeFunction<hb_unicode_compose_func_tFunction>>;
