Trait NodeEventListener 

pub trait NodeEventListener: Send + Sync {
    // Required method
    fn on_event(&self, event: NodeEvent);
}

Callback interface for receiving node events.

on_event is invoked from the SDK’s internal event-dispatch task. Implementations should be cheap and non-blocking; to update UI, dispatch to the main thread from inside the handler.

Installed via NodeBuilder::with_event_listener(...) so events emitted during node bring-up are captured. The polling-style Node::stream_node_events() API is still available for callers that prefer to drive events themselves.

Required Methods

fn on_event(&self, event: NodeEvent)
