neither the trait or the self type are at the same nesting level as the `impl` [INFO] [stderr] = note: items in an anonymous const item (`const _: () = { ... }`) are treated as in the same scope as the anonymous const's declaration for the purpose of this lint [INFO] [stderr] = note: this warning originates in the derive macro `Fail` (in Nightly builds, run with -Z macro-backtrace for more info)
