Aliased Type

struct Cmap<'a> { /* private fields */ }

Implementations

impl<'a> Cmap<'a>

pub fn version(&self) -> u16

Table version number (0).

pub fn num_tables(&self) -> u16

Number of encoding tables that follow.

pub fn encoding_records(&self) -> &'a [EncodingRecord]

impl Cmap<'_>

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

Map a codepoint to a nominal glyph identifier

This uses the first available subtable that provides a valid mapping.

Note:

Mapping logic is currently only implemented for the most common subtable formats.

pub fn closure_glyphs( &self, unicodes: &IntSet<u32>, glyph_set: &mut IntSet<GlyphId>, )

impl<'a, T> TableRef<'a, T>

pub fn resolve_offset<O: Offset, R: FontRead<'a>>( &self, offset: O, ) -> Result<R, ReadError>

Resolve the provided offset from the start of this table.

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

Return a reference to this table’s raw data.

We use this in the compile crate to resolve offsets.

pub fn shape(&self) -> &T

Return a reference to the table’s ‘Shape’ struct.

This is a low level implementation detail, but it can be useful in some cases where you want to know things about a table’s layout, such as the byte offsets of specific fields.

Trait Implementations

impl<'a> FontRead<'a> for Cmap<'a>

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

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

impl TopLevelTable for Cmap<'_>

const TAG: Tag

impl<'a, T: Clone> Clone for TableRef<'a, T>

fn clone(&self) -> TableRef<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.
