Implementations

impl<'a> CmapSubtable<'a>

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

Return the FontData used to resolve offsets for this table.

pub fn format(&self) -> u16

Format number is set to 0.

impl<'a> CmapSubtable<'a>

pub fn language(&self) -> u32

pub fn map_codepoint(&self, codepoint: impl Into<u32>) -> Option<GlyphId>

Attempts to map the given codepoint to a nominal glyph identifier using the underlying subtable.

pub fn iter(&self) -> CmapSubtableIter<'a>

Returns an iterator over all (codepoint, glyph identifier) pairs in the subtable.

Malicious and malformed fonts can produce a large number of invalid pairs. Use Self::iter_with_limits to generate a pruned sequence that is limited to reasonable values.

pub fn iter_with_limits(&self, limits: CmapIterLimits) -> CmapSubtableIter<'a>

Returns an iterator over all (codepoint, glyph identifier) pairs in the subtable within the given limits.

Trait Implementations

impl<'a> Clone for CmapSubtable<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for CmapSubtable<'a>

fn read(data: FontData<'a>) -> Result<Self, ReadError>

Read an instance of Self from the provided data, performing validation.

impl MinByteRange for CmapSubtable<'_>

fn min_byte_range(&self) -> Range<usize>
