// 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.
