Can you describe more broadly the problem you are trying to solve?
Why do you need to distinguish connection timeout from response timeout?

I'm working on an RPC framework.
If the connection timeouts, I can try again.
If the response timeouts, I can't retry. Because the request may have been sent.

Hi there,
We have decided that our experiment to allow questions on the issue tracker has not had the outcome we desired, so I am closing this issue. I'm sorry that we can't answer your question here.

There are many other methods to get help if you're still curious:

• Stack Overflow with questions tagged "go"

• The Go Forum, a web-based forum

• Gophers Slack, use the invite app for access. The #general channel is a good starting point.

• Go Community on Hashnode with questions and posts tagged with "go"

• The golang-nuts mailing list

• IRC channel #go-nuts on Freenode

Thanks
