Trait AppEventSource 

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

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

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

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

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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
