alec-deason opened issue #8477:

#8441 recently added support for additional_derives in wasmtime::component::bindgen but the new version appears not to apply the derives to all types. In particular it seems to miss variants which are only used as fields in records, as in this definition:

package test:bindgen-test;

interface types {
    variant inner-variant {
        a,
        b,
        c
    }
    record outer-record{
        inner: inner-variant
    }
}

world bindgen-test {
    use types.{outer-record};
    export test-failure: func() -> outer-record;
}

In my testing the derives will be applied to OuterRecord but not to InnerVariant.

Attached is a complete test case which fails to compile.

@alec-deason Sorry about that! I added the fix in #8482.
