Struct write_fonts::tables::variations::Tuple

pub struct Tuple {
    pub values: Vec<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: Vec<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 Tuple

pub fn new(values: Vec<F2Dot14>) -> Self

Construct a new Tuple

impl Tuple

pub fn len(&self) -> u16

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for Tuple

fn clone(&self) -> Tuple

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tuple

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

Formats the value using the given formatter.

impl Default for Tuple

fn default() -> Tuple

Returns the “default value” for a type.

impl FontWrite for Tuple

fn write_into(&self, writer: &mut TableWriter)

Write our data and information about offsets into this TableWriter.

fn table_type(&self) -> TableType

The type of this table.

impl FromObjRef<Tuple<'_>> for Tuple

fn from_obj_ref(obj: &Tuple<'_>, offset_data: FontData<'_>) -> Self

Convert from to an instance of Self, using the provided data to resolve offsets.

impl Hash for Tuple

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Tuple

fn cmp(&self, other: &Tuple) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Tuple

fn eq(&self, other: &Tuple) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Tuple

fn partial_cmp(&self, other: &Tuple) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Validate for Tuple

fn validate_impl(&self, ctx: &mut ValidationCtx)

Validate this table.

fn validate(&self) -> Result<(), ValidationReport>

Ensure that this table is well-formed, reporting any errors.

impl Eq for Tuple

impl StructuralPartialEq for Tuple
