Atomicly SetIfAbsent #54

Is there anyway to atomicly set a value if one does not already exist?

I have tried a couple different things and they don't seem to work for my use case, I have examples if wanted:

  • CompareAndSwap(key, nil, value) which doesn't seem to work on unset keys.
  • GetOrSet and GetOrCompute but those don`t seem to be threadsafe.

If there is currently no way to do this would you be open to a PR adding it?

Thanks
