Struct FontFeatures 

pub struct FontFeatures { /* private fields */ }

A set of OpenType features requested for shaping.

Stack-allocated for the common case of ≤4 features.

Implementations

impl FontFeatures

pub fn new() -> Self

Create an empty feature set.

pub fn push(&mut self, feature: FontFeature)

Add a feature to the set.

pub fn from_slice(features: &[FontFeature]) -> Self

Create from a slice of features.

pub fn len(&self) -> usize

Number of features.

pub fn is_empty(&self) -> bool

Whether the feature set is empty.

pub fn iter(&self) -> impl Iterator<Item = &FontFeature>

Iterate over features.

pub fn canonicalize(&mut self)

Sort features by tag for deterministic hashing.

Trait Implementations

impl Clone for FontFeatures

fn clone(&self) -> FontFeatures

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontFeatures

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

Formats the value using the given formatter.

impl Default for FontFeatures

fn default() -> FontFeatures

Returns the “default value” for a type.

impl Hash for FontFeatures

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 PartialEq for FontFeatures

fn eq(&self, other: &FontFeatures) -> 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.
