@lnicola this PR is now blocked on us syncing with rust-lang/rust as this touches the proc-macro stuff causing CI to run on nightly 😬 so would be nice if we could do a sync by next week, the PR isn't finished yet and once it is I will only merge it at the start of the week. Just letting you know :) |
|
Yup, will do one soon! |

☔ The latest upstream changes (presumably #17584) made this pull request unmergeable. Please resolve the merge conflicts. |

We should be able to start dropping support for some proc-macro server API versions soon should the code here become too complicated.

I reckon this PR will break stuff, will install the modified proc-macro server and use that for the week to see if something is breaking there as well |

Headsup @vlad20012, this PR and #17601 make changes to the proc-macro server API adding a new version, adding two more u32s to literals on the wire, and one more u32 to idents. I have not really given this much thought tbf so please comment if you think we can do better than that. Its not set in stone until the next sync to rustc which will update the proc-macro server then.

Note that syncs are currently on hold until we figure out the new rustc_pattern_analysis story.

that's fine, probably better even as it gives me more time to test the proc-macro server :D

@Veykril Thanks for mentioning! The changes looks good to me

The changes in Spacing seems unrelated to the wire changes 🤔

Yes that is not yet used, and iirc it won't ever make it to the proc-macro server either so you should be safe to ignore that. For you only the changes in proc-macro-api ought to be really relevant.

@Veykril did you mean to break |

Ah no I didn't |
