/* If you are trying to use CompletionQueue::AsyncNext with a time class that |
|
isn't either gpr_timespec or std::chrono::system_clock::time_point, you |
|
will most likely be looking at this comment as your compiler will have |
|
fired an error below. In order to fix this issue, you have two potential |
|
solutions: |
|
|
|
1. Use gpr_timespec or std::chrono::system_clock::time_point instead |
|
2. Specialize the TimePoint class with whichever time class that you |
|
want to use here. See below for two examples of how to do this. |
