taskConsumer := &TaskConsumer{}
name, err := taskQueue.AddConsumer("task-consumer", taskConsumer)

At your example i give error on &TaskConsumer{}. Couldn't find that

So TaskConsumer would be a struct you have to define on your own. And it needs to implement the Consumer interface so that you can use it in the AddConsumer() function. There are some examples of that in this repo.
