pub struct Emitter { /* private fields */ }Expand description
A clone-able emission handle (an Arc<EventBus>). Option<Emitter>
at every emission site: None (tests, unwired constructions) is a
documented no-op, so the subsystems never need a bus to exist.
Implementations§
Source§impl Emitter
impl Emitter
Sourcepub fn emit(&self, kind: EventKind, payload: EventPayload)
pub fn emit(&self, kind: EventKind, payload: EventPayload)
Emit one event; drop-and-count on a full/undrained queue.
Sourcepub fn for_upstream(&self, upstream: &str) -> UpstreamEmitter
pub fn for_upstream(&self, upstream: &str) -> UpstreamEmitter
An emitter pre-bound to one upstream’s label (breaker transitions
and endpoint events): keeps upstream consistent across every
event that upstream’s state machines emit.
