Struct SustainedDetector 

pub struct SustainedDetector { /* private fields */ }

Fires when a state-based condition remains true for at least duration.

On each check():

• If the condition is true and became_true_at is None, record now.
• If the condition is true and became_true_at is Some(t), return true when now - t >= duration.
• If the condition is false, reset became_true_at to None.

This detector needs periodic timer checks because it depends on elapsed wall-clock time.

Implementations

impl SustainedDetector

pub fn new( condition: Arc<dyn Fn(&State) -> bool + Send + Sync>, duration: Duration, ) -> Self

Create a new sustained detector.

• condition: evaluated against the current state.
• duration: how long the condition must remain true before firing.

Trait Implementations

impl PatternDetector for SustainedDetector

fn check( &self, state: &State, _event: Option<&SessionEvent>, now: Instant, ) -> bool

Evaluate whether the pattern is currently triggered.

fn reset(&self)

Reset the detector’s internal state (counters, timestamps, etc.).

fn needs_timer(&self) -> bool

Whether this detector requires periodic timer checks.
