I've added MustUse here but not removed it from the ALLOW_LIST above, because you also seem to not have done this for the other attributes. Is this correct?

I've just rewritten the naked attribute, so this shouldn't be necessary anymore. but dw, I'll do the rebase on there

These commits modify tests/rustdoc-json.
rustdoc-json is a public (but unstable) interface.

Please ensure that if you've changed the output:

  • It's intentional.
  • The FORMAT_VERSION in src/librustdoc-json-types is bumped if necessary.

rustdoc-json-types is a public (although nightly-only) API. If possible, consider changing src/librustdoc/json/conversions.rs; otherwise, make sure you bump the FORMAT_VERSION constant.

☔ The latest upstream changes (presumably #142794) made this pull request unmergeable. Please resolve the merge conflicts.
