The HVAR (Horizontal Metrics Variations) table

Fields

version: MajorMinor

Major version number of the horizontal metrics variations table — set to 1. Minor version number of the horizontal metrics variations table — set to 0.

item_variation_store: OffsetMarker<ItemVariationStore, WIDTH_32>

Offset in bytes from the start of this table to the item variation store table.

advance_width_mapping: NullableOffsetMarker<DeltaSetIndexMap, WIDTH_32>

Offset in bytes from the start of this table to the delta-set index mapping for advance widths (may be NULL).

lsb_mapping: NullableOffsetMarker<DeltaSetIndexMap, WIDTH_32>

Offset in bytes from the start of this table to the delta-set index mapping for left side bearings (may be NULL).

rsb_mapping: NullableOffsetMarker<DeltaSetIndexMap, WIDTH_32>

Offset in bytes from the start of this table to the delta-set index mapping for right side bearings (may be NULL).

Implementations

impl Hvar

pub fn new( version: MajorMinor, item_variation_store: ItemVariationStore, advance_width_mapping: Option<DeltaSetIndexMap>, lsb_mapping: Option<DeltaSetIndexMap>, rsb_mapping: Option<DeltaSetIndexMap> ) -> Self

Construct a new Hvar

Trait Implementations

impl Clone for Hvar

fn clone(&self) -> Hvar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Hvar

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

Formats the value using the given formatter.

impl Default for Hvar

fn default() -> Hvar

Returns the “default value” for a type.

impl<'a> FontRead<'a> for Hvar

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

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

impl FontWrite for Hvar

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 Hash for Hvar

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 Hvar

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

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

fn partial_cmp(&self, other: &Hvar) -> 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 TopLevelTable for Hvar

const TAG: Tag = _

The table’s tag.

impl Validate for Hvar

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 Hvar

impl StructuralEq for Hvar

impl StructuralPartialEq for Hvar
