worker.getHeapStatistics()

• 返回：<Promise>

  ¥Returns: <Promise>

此方法返回一个 Promise，它将解析为与 v8.getHeapStatistics() 相同的对象；如果工作线程停止运行，则返回 ERR_WORKER_NOT_RUNNING 错误并拒绝。此方法允许从实际线程外部观察统计信息。

¥This method returns a Promise that will resolve to an object identical to v8.getHeapStatistics(), or reject with an ERR_WORKER_NOT_RUNNING error if the worker is no longer running. This methods allows the statistics to be observed from outside the actual thread.
