Struct NoOpEventBus 

pub struct NoOpEventBus;

A non-generic, type-erased no-op event bus.

Unlike NoOpPublisher<E>, this single struct can publish any event type without being parameterized. Use it in contexts where a concrete bus instance is required but no event forwarding is desired.

This eliminates the Option<event_bus> anti-pattern in services — a service can always hold an Arc<NoOpEventBus> and call publish() unconditionally.

Example

use backbone_messaging::NoOpEventBus;

let bus = NoOpEventBus::new();
bus.publish(my_event).await?; // silently discarded

Implementations

impl NoOpEventBus

pub fn new() -> Self

pub async fn publish<E: Send + 'static>( &self, _event: E, ) -> Result<(), EventError>

Publish any event — always succeeds, does nothing.

Trait Implementations

impl Default for NoOpEventBus

fn default() -> Self

Returns the “default value” for a type.
