Type Alias GlyphVariationDataHeader

pub type GlyphVariationDataHeader<'a> = TableRef<'a, GlyphVariationDataHeaderMarker>;

The GlyphVariationData table

Aliased Type

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

Implementations

impl<'a> GlyphVariationDataHeader<'a>

pub fn tuple_variation_count(&self) -> TupleVariationCount

A packed field. The high 4 bits are flags, and the low 12 bits are the number of tuple variation tables for this glyph. The number of tuple variation tables can be any number between 1 and 4095.

pub fn serialized_data_offset(&self) -> Offset16

Offset from the start of the GlyphVariationData table to the serialized data

pub fn serialized_data(&self) -> Result<FontData<'a>, ReadError>

Attempt to resolve serialized_data_offset.

pub fn tuple_variation_headers( &self, ) -> VarLenArray<'a, TupleVariationHeader<'_>>

Array of tuple variation headers.

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 GlyphVariationDataHeader<'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.
