Ideally it should not be exposed at all because there already is a method for
getting the proper structure.  And that method (or those methods) already use ::new() so with this patch it just fails.  Tests, examples, etc.  Instead of fixing that I would, probably, just not expose them.  I don't see a reason for them being public.
