Struct InMemoryBus 

pub struct InMemoryBus { /* private fields */ }

In-memory bus backed by tokio::sync::broadcast.

Implementations

impl InMemoryBus

pub fn new(capacity: usize) -> Self

Create a new bus with the given channel capacity. Lagged receivers will skip missed events (lossy).

pub fn default_capacity() -> Self

Default capacity suitable for most single-process deployments.

Trait Implementations

impl EventBus for InMemoryBus

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

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

Publish an event to all subscribers.

fn subscribe(&self) -> Box<dyn EventSubscriber>

Create a new subscriber that receives all future events.

fn subscriber_count(&self) -> usize

Number of active subscribers.
