Trait EventBus 

pub trait EventBus: EventEmitter {
    // Provided method
    fn collected_events<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = Vec<Event>> + Send + 'async_trait>>
       where Self: Sync + 'async_trait,
             'life0: 'async_trait { ... }
}

Event sink that supports emission and optional collection.

Every EventBus is an EventEmitter. Embedders that want to inspect emitted events override collected_events; production hosts inherit the no-op default.

Provided Methods

fn collected_events<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Vec<Event>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Return all collected events. Defaults to an empty Vec for buses that do not retain events.
