// Many of our UI tests require the "derive" feature to function properly. In
// particular:
// - Some tests directly include `zerocopy-derive/tests/include.rs`, which
//   derives traits on the `AU16` type.
// - The file `invalid-impls.rs` directly includes `src/util/macros.rs` in order
//   to test the `impl_or_verify!` macro which is defined in that file.
//   Specifically, 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.
