Implementations§

Source§

impl<'a> Coverage<'a>

Source

pub fn is_valid(&self) -> bool

Returns true if the coverage table is valid.

Source

pub fn get(&self, glyph_id: GlyphId) -> Option<u16>

Returns the coverage index for the specified glyph.

Source

pub fn indices_with(&self, f: impl FnMut(GlyphId, u16) -> bool) -> Option<bool>

Invokes the specified closure with all (glyph, coverage) pairs in the table. Returning false from the closure will end enumeration early.
