This fixes #73363

Unfortunately I can't add a test for this since this bug is obscured by the cross-crate bug, being fixed in #73363 . Tests will be added later.

The test would basically be a test version of the code in #73363 . We could also land this PR after #73363 , and I can just add tests in the PR itself. Either way, would be nice to get code review while we wait for this PR stack to move forward.

The test would basically be a test version of the code in #73363 . We could also land this PR after #73363 , and I can just add tests in the PR itself.

I think that would be easier to do, with you rebasing off of/cherry-picking the commits from #73101.

@Manishearth

Yep, that's what I'm doing locally, but I realized that the fix itself was independent of your stuff, it's just that it's impossible to test without your stuff.

@Manishearth

Another fix for this might be to not visit hidden modules in the embargo visitor. This might break things.

Should we wait for @jyn514's work to be merged first? Otherwise r=me. Thanks @Manishearth !

Yes, that's what I was saying earlier. We have to wait since the test won't pass otherwise

#73101 just landed so I think this should be good to go after a rebase :)

Stabilize intra-doc links

Fixes rust-lang#43466

Thanks to the great work of @jyn514 in getting the [cross-crate reexport issue](rust-lang#65983) in intra-rustdoc links fixed, I think we're now in a position to stabilize this feature.

The tracking issue currently has two unresolved issues:

 - <s>behavior around doc(hidden): This is fixed in rust-lang#73365, which is just waiting for CI and should land tomorrow. It's also a pretty niche bug so while I expect it to land soon I don't think we need to block stabilization on it anyway.</s>
 - Non-identifier primitive types like slices: This was not a part of the original RFC anyway, and is a pretty niche use case

The feature itself, sans rust-lang#65983, has been shipped on nightly for three years now, with people using it on docs.rs. rust-lang#65983 itself is not an overwhelmingly central bit of functionality; the reason we elected to block stabilization on it was that back in 2017 it was not possible to fix the issue without some major refactorings of resolve, and we did not want to stabilize something that had such a potentially unfixable bug.

Given that we've fixed it, I see no reason to delay stabilization on this long awaited feature. It's possible that the latest patches have problems, however we _have_ done crater runs of some of the crucial parts. Furthermore, that's what the release trains are for, we will have a solid three months to let it ride the trains before it actually hits the stable compiler.
