Also emit `missing_docs` lint with `--test` to fulfil expectations #130025

Urgau · 2024-09-06T10:35:10Z

This PR removes the "test harness" suppression of the missing_docs lint to be able to fulfil #[expect] (expectations) as it is now "relevant".

I think the goal was to maybe avoid false-positive while linting on public items under #[cfg(test)] but with effective visibility we should no longer have any false-positive.

Another possibility would be to query the lint level and only emit the lint if it's of expect level, but that is even more hacky.

Fixes #130021

Seems so, actually looking at the test?

Hi, thanks for the contribution. May I ask if this PR would be cherry-picked to a patch release like 1.81.1?

Urgau · 2024-09-20T07:40:50Z

Due to our fast release cycle, we don't backport to stable simple bug-fixes, only security fixes or major regressions fixes.

#[expect(missing_bugs)] never worked on stable, so it's not technically a regression either, making it unlikely to get beta-backported either.

workingjubilee · 2024-09-20T15:50:26Z

great new lint, expect(missing_bugs) so that you can be sure your code is buggy :^)
