There was a problem hiding this comment.
Let's add some tests. Since this requires nightly, testing is a bit awkward:
- You define a new "integration test" that itself has a top-level
MODULE.bazelfile where you register a nightly toolchain. - Then you update the continuous testing definitions to add a new environment that uses that.
- The results should immediately show up in CI testing results for the PR.

This attribute can be set to the label of a target that provides
UnstableRustFeaturesInfo, which maps a label to a set of unstable features allowed for that label. The intent is to provide a way to centrally manage the use of unstable features, without having to use-Zallow-features=manually inrustc_flagsfor every affected target.
