Module EventBus 

Plugin event bus: publish/subscribe channel for plugin lifecycle events.

Handlers register via register_handler and receive every subsequent emit call. Errors from individual handlers are logged but do not abort delivery to other handlers.

Structs

PluginEventBus

Fan-out event bus: each emit delivers to all registered handlers.

Enums

PluginEvent

Events published through the bus during the plugin lifecycle.

Traits

PluginEventHandler

Async handler trait for plugin events.
