Struct FontFeatureSet

source
pub struct FontFeatureSet<'a> { /* private fields */ }
Expand description

Represents a set of features in a FontFeatures configuration, the features state is managed together.

Implementations§

source§

impl FontFeatureSet<'_>

source

pub fn names(&self) -> &'static [FontFeatureName]

Gets the OpenType name of the features.

source

pub fn state(&self) -> FontFeatureState

Gets the current state of the features.

Returns Auto if the features are mixed.

source

pub fn is_enabled(&self) -> bool

If the features are explicitly enabled.

source

pub fn is_disabled(&self) -> bool

If the features are explicitly disabled.

source

pub fn is_auto(&self) -> bool

If the features are auto enabled , or in a mixed state.

source

pub fn set(self, state: impl Into<FontFeatureState>) -> FontFeatureState

Set the feature state.

Returns the previous state.

source

pub fn enable(self)

Enable the feature.

source

pub fn disable(self)

Disable the feature.

source

pub fn auto(self)

Set the feature to auto.
