Generic MessageBus trait

Required Methods§

Source

fn publish<'life0, 'life1, 'async_trait>( &'life0 self, topic: &'life1 str, message: Arc<M>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Publish a message Note async but not defined as such because this is used dynamically

Source

fn request_timeout(&self) -> Duration

Get the request_timeout

Source

fn subscribe<'life0, 'life1, 'async_trait>( &'life0 self, topic: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn Subscription<M>>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Subscribe to a topic on the bus

Source

fn shutdown<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Shut down

Provided Methods§

Source

fn request<'life0, 'life1, 'async_trait>( &'life0 self, topic: &'life1 str, message: Arc<M>, ) -> Pin<Box<dyn Future<Output = Result<Arc<M>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Request/response - as publish() but returns a result
