Event handler trait for processing events

Required Methods

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

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

Handle an event

fn name(&self) -> &str

Get handler name for debugging

fn event_types(&self) -> Vec<&'static str>

Get event types this handler is interested in

Provided Methods

fn is_wildcard(&self) -> bool

Whether this handler should receive all events (wildcard)

fn priority(&self) -> i32

Get handler priority (affects processing order)
