Type Alias TupleVariationHeader

pub type TupleVariationHeader<'a> = TableRef<'a, TupleVariationHeaderMarker>;

TupleVariationHeader

Aliased Type

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

Implementations

impl<'a> TupleVariationHeader<'a>

pub fn read(data: FontData<'a>, axis_count: u16) -> Result<Self, ReadError>

A constructor that requires additional arguments.

This type requires some external state in order to be parsed.

impl<'a> TupleVariationHeader<'a>

pub fn variation_data_size(&self) -> u16

The size in bytes of the serialized data for this tuple variation table.

pub fn tuple_index(&self) -> TupleIndex

A packed field. The high 4 bits are flags (see below). The low 12 bits are an index into a shared tuple records array.

impl<'a> TupleVariationHeader<'a>

pub fn peak_tuple(&self) -> Option<Tuple<'a>>

Peak tuple record for this tuple variation table — optional, determined by flags in the tupleIndex value. Note that this must always be included in the ‘cvar’ table.

pub fn intermediate_start_tuple(&self) -> Option<Tuple<'a>>

Intermediate start tuple record for this tuple variation table — optional, determined by flags in the tupleIndex value.

pub fn intermediate_end_tuple(&self) -> Option<Tuple<'a>>

Intermediate end tuple record for this tuple variation table — optional, determined by flags in the tupleIndex value.

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> FontReadWithArgs<'a> for TupleVariationHeader<'a>

fn read_with_args(data: FontData<'a>, args: &u16) -> Result<Self, ReadError>

read an item, using the provided args.

impl ReadArgs for TupleVariationHeader<'_>

type Args = u16

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.
