QueryRouterEventUnion = ClassifyStartEvent | ClassifyCompleteEvent | ClassifyErrorEvent | RetrieveStartEvent | RetrieveVectorEvent | RetrieveGraphEvent | RetrieveRerankEvent | RetrieveCompleteEvent | RetrieveFallbackEvent | ResearchStartEvent | ResearchPhaseEvent | ResearchCompleteEvent | GenerateStartEvent | GenerateCompleteEvent | RouteCompleteEvent | GitHubIndexStartEvent | GitHubIndexCompleteEvent | GitHubIndexErrorEvent

Discriminated union of all QueryRouter lifecycle events. The type field serves as the discriminant for exhaustive matching.

Example

function handleEvent(event: QueryRouterEventUnion) {
  switch (event.type) {
    case 'classify:start':
      console.log(`Classifying: ${event.query}`);
      break;
    case 'retrieve:vector':
      console.log(`Vector search returned ${event.chunkCount} chunks`);
      break;
    case 'route:complete':
      console.log(`Done in ${event.durationMs}ms`);
      break;
  }
