What did you do?
https://play.golang.org/p/CdUXyBdUq2g
What did you expect to see?
Using type assertion or errors.As
for things like *net.OpError
on errors returned by NewClientConn
works.
What did you see instead?
The returned error is a *errors.errorString
due to the fact that it's returned using fmt.Errorf
and %v
instead of %w
.
