alternate_feature: OffsetMarker<Feature, WIDTH_32>

Offset to an alternate feature table, from start of the FeatureTableSubstitution table.

Implementations

impl FeatureTableSubstitutionRecord

pub fn new(feature_index: u16, alternate_feature: Feature) -> Self

Construct a new FeatureTableSubstitutionRecord

Trait Implementations

impl Clone for FeatureTableSubstitutionRecord

fn clone(&self) -> FeatureTableSubstitutionRecord

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureTableSubstitutionRecord

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

Formats the value using the given formatter.

impl Default for FeatureTableSubstitutionRecord

fn default() -> FeatureTableSubstitutionRecord

Returns the “default value” for a type.

impl FontWrite for FeatureTableSubstitutionRecord

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<FeatureTableSubstitutionRecord> for FeatureTableSubstitutionRecord

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

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

impl Hash for FeatureTableSubstitutionRecord

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 FeatureTableSubstitutionRecord

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

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

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

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 FeatureTableSubstitutionRecord
