Struct Features 

pub struct Features(/* private fields */);

The OpenType features a run is shaped with, beyond the ones the shaper turns on for every run.

These travel on the run. A painter that draws glyphs has them already; one that draws characters has to ask the face for the same features, or it draws different glyphs at the positions the engine measured.

A book is set in a handful of these and holds hundreds of thousands of runs, so the runs share one set rather than each carrying a list of its own.

Implementations

impl Features

pub const NONE: Features

Nothing beyond the default set.

pub fn new(small_caps: bool, settings: Vec<FeatureSetting>) -> Features

The features of one run: smcp where the face draws the small capitals, and whatever the sheet asked for.

pub fn small_caps(&self) -> bool

Whether the run is set in the face’s own small capitals.

pub fn settings(&self) -> &[FeatureSetting]

What the sheet asked for, in the order the shaper reads it.
