Struct InMemoryEventBus 

pub struct InMemoryEventBus { /* private fields */ }

In-memory event bus implementation using broadcast channels

Implementations

impl InMemoryEventBus

pub fn new() -> Self

pub fn with_capacity(capacity: usize) -> Self

Trait Implementations

impl Default for InMemoryEventBus

fn default() -> Self

Returns the “default value” for a type.

impl EventBus for InMemoryEventBus

fn publish<'life0, 'async_trait>( &'life0 self, event: CloudEvent, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Publish an event to the bus

fn subscribe<'life0, 'life1, 'async_trait>( &'life0 self, event_type: &'life1 str, ) -> Pin<Box<dyn Future<Output = EventSubscription> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Subscribe to events matching a specific type. The subscription starts receiving events from the point of subscription.

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

where Self: 'async_trait, 'life0: 'async_trait,

Subscribe to all events

fn unsubscribe<'life0, 'async_trait>( &'life0 self, _subscription: EventSubscription, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Unsubscribe a previously registered subscription

fn recv<'life0, 'life1, 'async_trait>( &'life0 self, subscription: &'life1 mut EventSubscription, ) -> Pin<Box<dyn Future<Output = Option<CloudEvent>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Receive the next event matching a subscription (blocking wait)
