What did you do (The steps to reproduce)?
The String() method in SendResult cause a panic when MessageQueue field is nil. This happens beacuse String() method tries to access MessageQueue.String() without checking if MessageQueue is nil.
What did you expect to see?
The String() method should not panic, even when MessageQueue is nil. Instead, it should return a string that clearly indicates MessageQueue is nil.
