Implementations

impl<'a> ClassDef<'a>

pub fn offset_data(&self) -> FontData<'a>

Return the FontData used to resolve offsets for this table.

pub fn class_format(&self) -> u16

Format identifier — format = 1

impl ClassDef<'_>

pub fn get(&self, gid: GlyphId16) -> u16

Get the class for this glyph id

pub fn iter(&self) -> impl Iterator<Item = (GlyphId16, u16)> + '_

Iterate over each glyph and its class.

This will not include class 0 unless it has been explicitly assigned.
