Out of curiosity, what does this do?
Compile top 1000 edition=2021 crates with edition=2024 and sees how it goes?

ehuss · 2024-03-23T23:37:28Z

It compiles them with 2021, collects diagnostics to migrate to 2024 and applies them, then compiles again with 2024 to ensures that works.

matthiaskrgr · 2024-03-23T23:43:30Z

Does this cover anything beyond the 2024 lint group?
rust-2024-compatibility static-mut-refs, unsafe-op-in-unsafe-fn

ehuss · 2024-03-24T02:30:04Z

This is just testing unsafe-op-in-unsafe-fn.
