pub trait AppEventSource: Send + Sync {
    // Required method
    fn subscribe<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = Receiver<AppEvent>> + Send + 'async_trait>>

}
Expand description

Source of AppEvents produced by the application core that front-ends can listen to for UI updates.

Implementations typically wrap an mpsc::Receiver<AppEvent> or forward events from an external transport (e.g. gRPC stream).

Required Methods§

Source

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

Obtain a receiver that yields application events. A fresh receiver should be returned on every call so multiple consumers can coexist.
