function useAsyncRunner(): AsyncRunner

Use an AsyncRunner. An AsyncRunner can be used to asynchronously run code in a Frame Processor on a separate, non-blocking Thread.

Example

function App() {
  const asyncRunner = useAsyncRunner()
  const frameOutput = useFrameOutput({
    onFrame(frame) {
      'worklet'
      const wasHandled = asyncRunner.runAsync(() => {
        'worklet'
        doSomeHeavyProcessing(frame)
        // Async task finished - dispose the Frame now.
        frame.dispose()
      })

      if (!wasHandled) {
        // `asyncRunner` is busy - drop this Frame!
        frame.dispose()
      }
    }
  })
}
