These were previously broken as they wouldn't set the inner bind value at all. We introduce a new
InnerBindValueKind
to handle them correctly.In addition this commit improves the internal panic handling of the multi connection implementation by either changing existing
unwrap()
calls to return an error instead or by usingexpect()
to provide an unique error message. This hopefully should make it easier to pin down future issues.
