Module observability 

Observability infrastructure for the Rustvello distributed task system.

Defines the EventEmitter trait, CompositeEmitter, and EventLevel for configurable event propagation to monitoring backends.

Structs

CompositeEmitter

Fans out events to multiple sinks, each with an associated EventLevel filter. A sink only receives events at or below its configured level.

NoopEmitter

A no-op event emitter that discards all events.

WorkerState

Tracks what a worker is currently doing (Phase 3C).

Enums

EventLevel

Granularity level for observable events.

LastResult

The outcome of the most recently completed invocation.

Traits

EventEmitter

Observable events emitted during task lifecycle.
