Struct ClassDefFormat3 

pub struct ClassDefFormat3<'a> { /* private fields */ }

ClassDefFormat3 (ISO/IEC 14496-22:2026).

Implementations

impl<'a> ClassDefFormat3<'a>

pub const MIN_SIZE: usize

pub fn resolve_offset<O: Offset, R: FontRead<'a, Args = ()>>( &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) -> &Self

👎Deprecated:

just use the base type directly

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.

pub fn class_format(&self) -> u16

Format identifier — format = 3

pub fn start_glyph_id(&self) -> GlyphId24

First glyph ID of the classValueArray

pub fn glyph_count(&self) -> Uint24

Size of the classValueArray

pub fn class_value_array(&self) -> &'a [BigEndian<Uint24>]

Array of Class Values — one per glyph ID

pub fn class_format_byte_range(&self) -> Range<usize>

pub fn start_glyph_id_byte_range(&self) -> Range<usize>

pub fn glyph_count_byte_range(&self) -> Range<usize>

pub fn class_value_array_byte_range(&self) -> Range<usize>

impl ClassDefFormat3<'_>

pub fn get(&self, gid: impl Into<GlyphId>) -> u32

Get the class for this glyph id
