Struct ClassSubtable 

pub struct ClassSubtable<'a> {
    data: FontData<'a>,
}

Maps the glyph indexes of your font into classes.

Fields

data: FontData<'a>

Implementations

impl<'a> ClassSubtable<'a>

pub const MIN_SIZE: usize

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) -> &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 first_glyph(&self) -> u16

Glyph index of the first glyph in the class table.

pub fn n_glyphs(&self) -> u16

Number of glyphs in class table.

pub fn class_array(&self) -> &'a [u8]

The class codes (indexed by glyph index minus firstGlyph). Class codes range from 0 to the value of stateSize minus 1.

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

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

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

Trait Implementations

impl<'a> Clone for ClassSubtable<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for ClassSubtable<'a>

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

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

impl<'a> MinByteRange<'a> for ClassSubtable<'a>

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

fn min_table_bytes(&self) -> &'a [u8]
