Warnings when running `rustdoc` on `rust/kernel/traits.rs`

[wedsonaf]

I'm getting the following warnings when running make rustdoc.

This is also visible on CI (example here), so it's not a configuration issue on my side

warning: unresolved link to `Box`

@TheSven73 it looks like this was introduced by 02138fd.

I'll fix. Should we let the CI error out on rustdoc warnings?

[wedsonaf]

I'll fix.

Thanks!

I think we should, in fact I was surprised to find out that we don't.

Same. The CI succeeded, so I didn't even look at rustdoc's output.
I'll add rustdoc err-on-warn to the fix PR.

Hm. There are plenty of other rustdoc warnings, not only coming from traits.rs. The amount and types of warnings appear to change depending on the platform being built.

IIRC, I did not enable it right away because we did not have yet docs for all public bits etc. But yes, we definitely want to enable it.
