Type Alias Cmap12

pub type Cmap12<'a> = TableRef<'a, Cmap12Marker>;

cmap Format 12: Segmented coverage

Aliased Type

struct Cmap12<'a> { /* private fields */ }

Implementations

impl<'a> Cmap12<'a>

pub fn format(&self) -> u16

Subtable format; set to 12.

pub fn length(&self) -> u32

Byte length of this subtable (including the header)

pub fn language(&self) -> u32

For requirements on use of the language field, see “Use of the language field in ‘cmap’ subtables” in this document.

pub fn num_groups(&self) -> u32

Number of groupings which follow

pub fn groups(&self) -> &'a [SequentialMapGroup]

Array of SequentialMapGroup records.

impl<'a> Cmap12<'a>

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

Maps a codepoint to a nominal glyph identifier.

pub fn iter(&self) -> Cmap12Iter<'a>

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

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 Cmap12<'a>

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

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

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.
