rust Implement RFC 3631: add rustdoc doc

Implementation of https://github.com/rust-lang/rfcs/pull/3631.

This implementation actually resulted in a lot of simplifications:

All cfg computation is now done in one place: propagate_doc_cfg.rs. Because (trait) impls are not retrieved at the same time as the other items, we cannot perform this computation in the clean process, it needs to be after.
Because there is cfg inheritance, we can keep track of them in one place (in propagate_doc_cfg.rs), meaning we don't need to copy an item's attributes to its children anymore. Only exception: impl items. For them we clone only cfg attributes.
propagate_doc_cfg.rs is also now much simpler, much less need to keep track of parents, since everything we need is handled by the new CfgInfo type.
I also suspect that Cfg::simplify_with could either be removed or at least used directly into propagate_doc_cfg.rs when we compute cfgs. Considering how big the PR already is, I'll do it in a follow-up.

I didn't remove the doc_cfg* features in this PR because some dependencies used in rustc (like stdarch) are using it, so we need to have a nightly released with this PR before I can switch to the new feature.

What remains to be done:

I'd also want to block the stabilization on landing https://github.com/rust-lang/rust/pull/138844 to avoid a stable rustdoc feature relying on externally observable hacks in rustc. The crater run in #138844 returned mostly clean, so I expect it to land soon.

Noted! And that will be a nice improvement, thanks!

Just one thing left for the cfg expansion missing: #[cfg_attr(blabla, derive(Debug))]. In this case, the cfg is not kept in the generated derive items. It's been in my TODO list for a long time now. ^^'

Just one thing left for the cfg expansion missing: #[cfg_attr(blabla, derive(Debug))]

Do you mean like in #138515? :)

Mar 25 '25 10:03 petrochenkov

You're my hero! Gonna need to handle this new attribute then. :)

I'll try and take a look at this impl

May 26 '25 20:05 Manishearth

Added missing docs, renamed some functions too to be easier to understand what they do just by their name (doc is good but good naming is important too :sweat_smile:). I applied the code improvement suggestion and improved the error message. Thanks a lot!
