Module event 

Event system for fabric observability.

The FabricEvent enum represents all observable events in the fabric. Events are pushed to an EventSink implementation — either stored in an EventRingBuffer for later inspection, or forwarded to sinks like StdoutSink for immediate output.

Structs

EventRingBuffer

Fixed-size ring buffer for storing recent events.

EventRingIter

Iterator over events in an EventRingBuffer.

NullSink

A sink that discards all events. Default no_std sink.

StdoutSink

A sink that prints events to stdout.

Enums

FabricEvent

An observable fabric event.

OpType

Data-plane operation types.

ResourceType

Resource types tracked by the observability system.

RewritePhase

Rewrite plan phases.

Traits

EventSink

Trait for consuming fabric events.

Functions

emit_event

Emit an event to the global sink (if one has been registered via set_global_sink). No-op if no sink is registered or if the std feature is disabled.

set_global_sink

Register a process-wide EventSink.
