As suggested by @camelid here, since doc_keyword and doc_primitive aren't meant to be stabilized, we could put them behind a same feature flag.

This is pretty much what it would look like (needs to update the tests too).

The tracking issue is #90418.

What do you think @rust-lang/rustdoc ?

This seems ... kind of unnecessary to me? We can document on the tracking issues that these aren't meant to be stabilized, I don't think it also needs to be in the source code of everything using them. And as you've noticed the logic for doc_primitive is pretty different from that of doc_keyword, so I don't think it's particularly useful to combine them.

This seems ... kind of unnecessary to me? We can document on the tracking issues that these aren't meant to be stabilized, I don't think it also needs to be in the source code of everything using them.

The standard library often uses the naming convention of X_internals to indicate that something is perma-unstable. Whereas, #![feature(doc_keyword)] doesn't give any indication that it's only meant for internal use. People don't necessarily look at tracking issues, so IMO it's best to indicate in the feature name that something is internal-only. Another example is #[rustc_layout(debug)] which is under the feature-gate rustc_attrs, not something like debug_layout.

If merging the feature gates would be too complicated, I'm okay to leave them separate, but I would prefer to merge them and make it clear in the name that they are internal-only.

I don't think it also needs to be in the source code of everything using them.

They're only used in the standard library and rustdoc IIUC, and this would reduce the number of feature gates necessary?

Hmm, ok, seems reasonable.

This is in the wrong section; it should be next to doc_notable_trait.

Also, can you create an actual tracking issue? We shouldn't just link to this PR.

It does link to the tracking issue. Unless I missed something?

Otherwise, I updated following your comments.

Sorry, maybe GitHub glitched and showed me the wrong page. Tracking issue looks good to me.

Create rustdoc_internals feature gate

This is pretty much what it would look like (needs to update the tests too).
