Struct Feature 

pub struct Feature {
    pub feature_params: NullableOffsetMarker<FeatureParams>,
    pub lookup_list_indices: Vec<u16>,
}

Available on crate feature tables only.

Feature Table

Fields

feature_params: NullableOffsetMarker<FeatureParams>

Offset from start of Feature table to FeatureParams table, if defined for the feature and present, else NULL

lookup_list_indices: Vec<u16>

Array of indices into the LookupList — zero-based (first lookup is LookupListIndex = 0)

Implementations

impl Feature

pub fn new( feature_params: Option<FeatureParams>, lookup_list_indices: Vec<u16>, ) -> Self

Construct a new Feature

Trait Implementations

impl Clone for Feature

fn clone(&self) -> Feature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Feature

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

Formats the value using the given formatter.

impl Default for Feature

fn default() -> Feature

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Feature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Feature

impl FontWrite for Feature

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<'a> FromObjRef<Feature<'a>> for Feature

fn from_obj_ref(obj: &Feature<'a>, _: FontData<'_>) -> Self

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

impl<'a> FromTableRef<Feature<'a>> for Feature

fn from_table_ref(from: &T) -> Self

impl Hash for Feature

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 Feature

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

Restrict a value to a certain interval.

impl PartialEq for Feature

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Feature

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Feature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Feature

impl Validate for Feature

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.
