1// The doc tests allow us to do a compile_fail test, which is cool and what we want, but we don't
2// want to expose this in the docs, so we use a private struct for that reason.
3//
4// Note we also bundle one that *does* compile with each, just to make sure they don't silently
5// not-compile by some different reason.
