RenderMetricsMsg class

Message sent periodically with renderer performance metrics.

When enabled via ProgramOptions.metricsInterval, the Program sends this message at the specified interval with current FPS, frame times, and render durations.

Example

@override
(Model, Cmd?) update(Msg msg) {
  return switch (msg) {
    RenderMetricsMsg(:final metrics) => (
      copyWith(
        fps: metrics.averageFps,
        frameTime: metrics.averageFrameTime,
      ),
      null,
    ),
    _ => (this, null),
  };
}
