Implementations

impl<'a> Subtable4<'a>

pub fn parse(data: &'a [u8]) -> Option<Self>

Parses a subtable from raw data.

pub fn glyph_index(&self, code_point: u32) -> Option<GlyphId>

Returns a glyph index for a code point.

Returns None when code_point is larger than u16.

pub fn codepoints(&self, f: impl FnMut(u32))

Calls f for each codepoint defined in this table.

Trait Implementations

impl<'a> Clone for Subtable4<'a>

fn clone(&self) -> Subtable4<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Subtable4<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result
