Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Matched

Every-match mode: the detector matched this tick.

Fields

output: DetectorOutput

Changed

Change mode (default): the detector’s output transitioned. old is None on the first evaluation.

Fields

old: Option<DetectorOutput>

new: DetectorOutput

ThresholdCrossed

Threshold mode: the predicate flipped.

Fields

value: f64

direction: ThresholdDirection

TemplateAppeared

Template mode: the best match score rose to or above the threshold.

Fields

score: f32

TemplateVanished

Template mode: the best match score fell below the threshold.

WatcherDegraded

The detector failed repeatedly; the watcher keeps running.

Fields

consecutive_errors: u32

TargetLost

The capture target disappeared (e.g. the watched window closed). Session-wide: delivered to every subscriber. Watchers stay registered; a TargetReattached follows if the target comes back.

TargetReattached

A previously lost capture target is available again. Session-wide.

Implementations

impl EventKind

pub fn is_session_level(&self) -> bool

Session-wide events that every subscriber should see, regardless of the watcher names their stream filters on.

Trait Implementations

impl Clone for EventKind

fn clone(&self) -> EventKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventKind

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

Formats the value using the given formatter.
