// it tests the verification portion of that macro, which is enabled when
// `cfg(any(feature = "derive", test))`. While `--cfg test` is of course passed
// to the code in the file you're reading right now, `trybuild` does not pass
// `--cfg test` when it invokes Cargo. As a result, this `trybuild` test only
// tests the correct behavior when the "derive" feature is enabled.
