   **Is your feature request related to a problem? (你需要的功能是否与某个问题有关?)**
   brpc在我们调用了done->Run()之后。会立即给客户端返回response，同时request和response会析构。
   
   request或response比较大。
   
   我想在返回response之后，利用request和response打印到本地日志（或远程日志）中。目前看来这个操作只能在调用done->Run()之前做。这个日志打印的开销（涉及序列化开销）会包含在一次请求响应的时间内。
   
   或者在调用done->Run()之前，给request和response 拷贝到新的变量中（比如CopyFrom）。然后在done->Run()之后用新的变量再做日志打印。在一次请求响应的时间内包含CopyFrom的开销。
   
   我想能不能在done->Run()只返回，但是request和response不析构呢？我们使用完再，自己调用方法析构掉。
