Implementations

impl ScreenReaderChord

pub fn new() -> ScreenReaderChord

pub fn key(&mut self, event: ChordEvent) -> bool

Feed one key event. true when it toggles the screen reader: the press of Enter under exactly Ctrl + Super, or the event that finds both volume keys held for VOLUME_HOLD.

pub fn deadline(&self) -> Option<Instant>

When the volume hold toggles if both keys stay down; the host arms a timer for it and calls Self::tick then.

pub fn tick(&mut self, now: Instant) -> bool

true once per hold, at or after Self::deadline.

pub fn reset(&mut self)

Forget held keys, as when the host loses keyboard focus and will not see their release.
