Type Alias IndexSubtable4

pub type IndexSubtable4<'a> = TableRef<'a, IndexSubtable4Marker>;

IndexSubTable4: variable-metrics glyphs with sparse glyph codes.

Aliased Type

struct IndexSubtable4<'a> { /* private fields */ }

Implementations

impl<'a> IndexSubtable4<'a>

pub fn index_format(&self) -> u16

Format of this IndexSubTable.

pub fn image_format(&self) -> u16

Format of EBDT image data.

pub fn image_data_offset(&self) -> u32

Offset to image data in EBDT table.

pub fn num_glyphs(&self) -> u32

Array length.

pub fn glyph_array(&self) -> &'a [GlyphIdOffsetPair]

One per glyph.

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 IndexSubtable4<'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.
