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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
