Enum unused not detected

[Villosse]

Summary

It seems gccrs is not detecting unused enums

Reproducer

I tried this code:

enum Foo {
    A,
    B,
}

Does the code make use of any (1.49) nightly feature ?

Actual behavior

There is no warning thrown

Expected behavior

I expected to see a warning on the unused enum
