Type Alias ClassDefFormat1

pub type ClassDefFormat1<'a> = TableRef<'a, ClassDefFormat1Marker>;

Class Definition Table Format 1

Aliased Type

struct ClassDefFormat1<'a> { /* private fields */ }

Implementations

impl<'a> ClassDefFormat1<'a>

pub fn class_format(&self) -> u16

Format identifier — format = 1

pub fn start_glyph_id(&self) -> GlyphId16

First glyph ID of the classValueArray

pub fn glyph_count(&self) -> u16

Size of the classValueArray

pub fn class_value_array(&self) -> &'a [BigEndian<u16>]

Array of Class Values — one per glyph ID

impl<'a> ClassDefFormat1<'a>

pub fn get(&self, gid: GlyphId16) -> u16

Get the class for this glyph id

pub fn iter(&self) -> impl Iterator<Item = (GlyphId16, u16)> + 'a

Iterate over each glyph and its class.

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 ClassDefFormat1<'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.
