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.

Dyn Compatibility

This trait is dyn compatible.

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