Struct write_fonts::tables::layout::VariationIndex

pub struct VariationIndex {
    pub delta_set_outer_index: u16,
    pub delta_set_inner_index: u16,
}

Variation index table

Fields

delta_set_outer_index: u16

A delta-set outer index — used to select an item variation data subtable within the item variation store.

delta_set_inner_index: u16

A delta-set inner index — used to select a delta-set row within an item variation data subtable.

Implementations

impl VariationIndex

pub fn new(delta_set_outer_index: u16, delta_set_inner_index: u16) -> Self

Construct a new VariationIndex

Trait Implementations

impl Clone for VariationIndex

fn clone(&self) -> VariationIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VariationIndex

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

Formats the value using the given formatter.

impl Default for VariationIndex

fn default() -> VariationIndex

Returns the “default value” for a type.

impl<'a> FontRead<'a> for VariationIndex

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

Read an instace of Self from the provided data, performing validation.

impl FontWrite for VariationIndex

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 From<VariationIndex> for DeviceOrVariationIndex

fn from(src: VariationIndex) -> DeviceOrVariationIndex

Converts to this type from the input type.

impl From<VariationIndex> for u32

fn from(value: VariationIndex) -> Self

Converts to this type from the input type.

impl Hash for VariationIndex

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 VariationIndex

fn cmp(&self, other: &VariationIndex) -> 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 VariationIndex

fn eq(&self, other: &VariationIndex) -> 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 VariationIndex

fn partial_cmp(&self, other: &VariationIndex) -> 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 VariationIndex

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 VariationIndex

impl StructuralPartialEq for VariationIndex
