Compilation succeeds even if there is #[inline] in the structure field.

[Danue1]

I tried this code:

struct Foo {
    #[inline]
    bar: String,
}

I expected to see this happen: Failing complilation.

Instead, this happened: Compilation success.

Some validation was added in #73461, but it looks like there are a few places that are missing. The ones I can see are struct fields, match arms, and macro definitions:

struct Foo {
    #[inline]
    bar: String,
}

match foo {
    #[inline]
    _ => {}
}

#[inline]
macro_rules! foo {
    () => {};
}

I believe that CheckAttrVisitor needs to include visitor methods for visit_arm and visit_struct_field and visit_macro_def.

Hmm, I think I can do it, so I'll try it.
