SECTION:hb-set @title: hb-set @short_description: Objects representing a set of integers hb.h
Set objects represent a mathematical set of integer values. They are used in non-shaping APIs to query certain sets of characters or glyphs, or other integer values. hb_set_create: (Xconstructor)
Creates a new, initially empty set.
Return value: (transfer full): The new hb_set_t

hb_set_next: @set: A set @codepoint: (inout): Input = Code point to query Output = Code point retrieved
Fetches the next element in @set that is greater than current value of @codepoint.
Set @codepoint to HB_SET_VALUE_INVALID to get started.
Return value: true if there was a next value, false otherwise

hb_set_next_many: @set: A set @codepoint: Outputting codepoints starting after this one. Use HB_SET_VALUE_INVALID to get started. @out: (array length=size): An array of codepoints to write to. @size: The maximum number of codepoints to write out.
Finds the next element in @set that is greater than @codepoint. Writes out codepoints to @out, until either the set runs out of elements, or @size codepoints are written, whichever comes first.
Return value: the number of values written.
