ValueRecord metrics variation record

Fields

value_tag: BigEndian<Tag>

Four-byte tag identifying a font-wide measure.

delta_set_outer_index: BigEndian<u16>

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

delta_set_inner_index: BigEndian<u16>

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

Implementations

impl ValueRecord

pub fn value_tag(&self) -> Tag

Four-byte tag identifying a font-wide measure.

pub fn delta_set_outer_index(&self) -> u16

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

pub fn delta_set_inner_index(&self) -> u16

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

Trait Implementations

impl Clone for ValueRecord

fn clone(&self) -> ValueRecord

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueRecord

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

Formats the value using the given formatter.

impl FixedSize for ValueRecord

const RAW_BYTE_LEN: usize = 8usize

The raw size of this type, in bytes.

impl Hash for ValueRecord

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 ValueRecord

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

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

fn partial_cmp(&self, other: &ValueRecord) -> 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<'a> SomeRecord<'a> for ValueRecord

fn traverse(self, data: FontData<'a>) -> RecordResolver<'a>

impl Zeroable for ValueRecord

fn zeroed() -> Self

Calls zeroed.

impl AnyBitPattern for ValueRecord
