Implementations

impl Detector

pub fn new(every: Duration) -> Self

pub fn observe( &mut self, workspace: &str, instance: u64, screen: &str, now: Instant, ) -> Option<Signal>

Feed a screen. Returns a signal only when the state changed. A session leaving a limit/login state reports Ready; a quiet session that never had one reports nothing.

pub fn forget(&mut self, workspace: &str, instance: u64)
