   class RocketMQMsgListener : public rocketmq::MessageListenerConcurrently
   {
   public:
       RocketMQMsgListener() {}
       virtual ~RocketMQMsgListener() {}
   
       virtual rocketmq::ConsumeStatus consumeMessage(const std::vector<rocketmq::MQMessageExt>& msgs)
       {
           for (size_t i = 0; i < msgs.size(); ++i)
           {
               callback_(msgs[i].getTopic(), msgs[i].getTags(), msgs[i].getMsgId(), msgs[i].getBody());
           }
   
           return rocketmq::CONSUME_SUCCESS;
       }
   
   请问，这个回调接口的参数是一个msg的vector，在其中我循环消费每一个消息，然后总体返回一个CONSUME_SUCCESS。那么如果有的消息消费失败了，有的消费成功了，怎么办呢？总体返回一个CONSUME_SUCCESS不行吧？对于每一个消息的具体消费情况，怎么给服务器答复呢？
