Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with r? rust-lang/libs-api @rustbot label +T-libs-api -T-libs to request review from a libs-api team reviewer. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

Stabilizing library features
Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
Changing public documentation in ways that create new stability guarantees
Changing observable runtime behavior of library APIs

error: could not compile `std` due to 538 previous errors

The job mingw-check failed! Check out the build log: (web) (plain)

Click to see the possible cause of the failure (guessed by this bot)

What is going on? Can someone explain please. I didn't even touch places where errors occurred.

Are there any ways to fix it without rewriting sys?

@mrMiiao Looking at the errors, it seems like you're missing the stability attributes

Well, not me... they're missing in std::sys. There's not a one. At all. I really don't know what to do. I'm not such a big person too rewrite std::sys, so I'm here asking for help... Will we never see std::sys as a public module?

Will we never see std::sys as a public module?

I highly doubt it. The structure of that module keeps changing; if we make it public we can never change it again which would be a problem.

This is purely an implementation detail of std. All parts of it that should be public are exposed, e.g., via std::fs, std::sync, ...

If there is any specific operation provided by std::sys that is not exposed otherwise, you could suggest making that public (probably best by starting a discussion on IRLO). But just a blanket "make all the internal details public and stable forever" is not going to work out, I think.

I agree with @RalfJung
We generally only expose things as unstable if they're intended to be stabilized one day or needed by another crate that is part of the standard library. This would be a massive departure from that policy so it would need prior discussion and I expect that discussion to point out better alternatives.

The oldest occurence is from 9e224c2, which is from the pre-1.0 days. In the years since then, std::sys still hasn't been exported, and the last attempt was met with strong criticism: rust-lang#97151 Thus, removing the "yet" part makes a lot of sense.
