Struct read_fonts::tables::variations::Tuple

pub struct Tuple<'a> {
    pub values: &'a [BigEndian<F2Dot14>],
}

A Tuple Record

The tuple variation store formats reference regions within the font’s variation space using tuple records. A tuple record identifies a position in terms of normalized coordinates, which use F2DOT14 values.

Fields

values: &'a [BigEndian<F2Dot14>]

Coordinate array specifying a position within the font’s variation space.

The number of elements must match the axisCount specified in the ‘fvar’ table.

Implementations

impl<'a> Tuple<'a>

pub fn values(&self) -> &'a [BigEndian<F2Dot14>]

Coordinate array specifying a position within the font’s variation space.

The number of elements must match the axisCount specified in the ‘fvar’ table.

impl<'a> Tuple<'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> Tuple<'a>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&self, idx: usize) -> Option<F2Dot14>

Trait Implementations

impl<'a> Clone for Tuple<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComputeSize for Tuple<'_>

fn compute_size(args: &u16) -> usize

Compute the number of bytes required to represent this type.

impl<'a> Debug for Tuple<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Tuple<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> FontReadWithArgs<'a> for Tuple<'a>

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

read an item, using the provided args.

impl ReadArgs for Tuple<'_>

type Args = u16

impl<'a> SomeRecord<'a> for Tuple<'a>
