Enum Features 

pub enum Features {
    Custom(Vec<FeatureInfo>),
    Mask(FeatureMask),
}

Type indicating the features to use when shaping text.

Variants

Custom(Vec<FeatureInfo>)

A custom feature list.

Only the supplied features will be applied when shaping text.

Mask(FeatureMask)

A mask of features to enable.

Unless you have a specific need for low-level control of the OpenType features to enable this variant should be preferred.

Enabled bits will be used to enable OpenType features when shaping text. When this variant of the Features enum is used some common features are enabled by default based on the script and language.

Trait Implementations

impl Clone for Features

fn clone(&self) -> Features

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Features

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

Formats the value using the given formatter.

impl Default for Features

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Features

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