IPC跨进程通信中是否支持异步返回数据

import { rpc } from '@kit.IPCKit'; 
 
class TestRemoteObject extends rpc.RemoteObject { 
  constructor(descriptor: string) { 
    super(descriptor); 
  } 
 
  async onRemoteMessageRequest(code: number, data: rpc.MessageSequence, reply: rpc.MessageSequence, option: rpc.MessageOption): Promise<boolean> { 
    if (code === 1) { 
      console.log("RpcServer: async onRemoteMessageRequest is called"); 
    } else { 
      console.log("RpcServer: unknown code: " + code); 
      return false; 
    } 
    await new Promise((resolve: (data: rpc.RequestResult) => void) => { 
      setTimeout(resolve, 100); 
    }) 
    return true; 
  } 
}
