Is it able to shutdown a Subscriber when its callback executing? [closed]
Well, I've tried to use one channel and topic A to control whether to subscribe to another topic B。So when handling B‘s callback,and in A's callback I am trying to shutdown subscriber to B , the program then block in the shutdown ,even B's callback is executed over , the shutdown method is still in block,Ctrl + C even can't kill it 。 Or in another word, is there a safe method to stop a runtime subscriber ?
