Module subscriber 

Generic event subscriber — reusable subscription wiring for any entity+event pair.

Eliminates the need for per-entity subscriber boilerplate. Modules register a GenericEventSubscriber with one or more Arc<dyn EventHandler<Event>> instances instead of implementing handler wiring from scratch for every entity.

Example

use backbone_messaging::subscriber::GenericEventSubscriber;
use backbone_messaging::crud_event::CrudEvent;

// Listen to StoredFile CRUD events and update a search index.
let subscriber = GenericEventSubscriber::<CrudEvent<StoredFile>>::new(
    vec!["entity.created", "entity.updated"],
    vec![Arc::new(SearchIndexHandler::new())],
);
