new lint `legacy_numeric_constants` #12312

pitaj · 2024-02-18T18:16:15Z

Rework of #10997

uses diagnostic items
does not lint imports of the float modules (use std::f32)
does not lint usage of float constants that look like f32::MIN

I chose to make the float changes because the following pattern is actually pretty useful

use std::f32;
let omega = freq * 2 * f32::consts::PI;

and the float modules are not TBD-deprecated like the integer modules.

Closes #10995

changelog: New lint [legacy_numeric_constants]
#12312

Hey, thank you for picking this up. This is on my todo list for next week, you should have a review by Friday, the latest. :)

The implementation looks good to me. I have two suggestions, where I would like to hear your thoughts about it. Once they've been discussed, this should be good to go.

And also thank you for your patience! The next review will be quicker :D

Thanks for taking a look. It seems like the next toolchain update should be on the 7th, which should include all the necessary diagnostic items.

I've made the changes you suggested, but wait to merge until I modify this to use the diag items.

pitaj · 2024-03-10T06:40:08Z

Welp, in working on the implementation I discovered that the diag items were still incomplete. So I guess we'll wait another two weeks 🙃

Okay, good to know :D I'll mark this as waiting for you. Once the next update is ready, you can push the update, and it should show up in my inbox again. Otherwise, you can also always ping me :D

@rustbot ready

This version looks good to me. I love how almost 1/3 of the implementation lines are just diagnostic symbols :D

I have a tiny nit in the tests, and then we can merge this. You can r=me after the next update.

✌️ @pitaj, you can now approve this pull request!

If @xFrednet told you to "r=me" after making some further change, please make that change, then do @bors r=xFrednet

xFrednet · 2024-03-24T10:49:20Z

Actually, let's not r+ it yet. I just remembered that @Manishearth suggested in the last meeting, that we discuss/notify others about new lints first to see if someone has comments on it. So let's keep this open for a week, to see if others have any thoughts on it. I'll write something for Zulip :)
