Trait EventHandler

pub trait EventHandler:
    Send
    + Sync
    + 'static {
    // Required method
    fn handle<'life0, 'life1, 'async_trait>(
        &'life0 self,
        events: &'life1 [Box<dyn Event>],
    ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

EventHandler trait defines the interface for how to handle the event.

Required Methods

fn handle<'life0, 'life1, 'async_trait>( &'life0 self, events: &'life1 [Box<dyn Event>], ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Processes and handles incoming events. The [DefaultEventHandlerImpl] implementation forwards events to frontend instances for persistence. We use &[Box<dyn Event>] to avoid consuming the events, so the caller can buffer the events and retry if the handler fails.
