rustdoc: Add support for `#[rustc_must_implement_one_of]` by WaffleLapkin · Pull Request #99235 · rust-lang/rust

WaffleLapkin · 2022-07-14T11:03:25Z

This PR adds support for #[rustc_must_implement_one_of] attribute added in #92164. There is a desire to eventually use this attribute of Read, so making it show up in docs is a good thing.

I "stole" the styling from cfg notes, not sure what would be a proper styling. Currently it looks like this:

Code to reproduce

#![feature(rustc_attrs)]

#[rustc_must_implement_one_of(a, b)]
pub trait Trait {
    fn req();
    fn a(){ Self::b() }
    fn b(){ Self::a() }
}

I wonder: if we have the trait DefId, I think most (if not all) other fields can be computed on demand, no?

Probably? What is the purpose of clean types anyway? 🤔

Types "cleaned up" for rustdoc use. :)

It just feels (from an outside perspective) that a lot of this can be replaced by DefId newtypes + getters 😅

unsafety or is_auto for example. :)

Well, can be done later on.

GuillaumeGomez · 2022-07-14T11:11:27Z

Also: please add a test in src/test/rustdoc to ensure the attribute is generated in the HTML as expected.

fmease · 2022-07-14T15:37:52Z

Slightly off-topic: For T-rustdoc reviewers and for future reference, this is how the equivalent feature in Haskell ({-# MINIMAL … #-}) looks like in the documentation generated by Haddock:

WaffleLapkin · 2022-07-17T17:03:27Z

Took me a while to figure out how to do rustdoc tests, but I added the test 😄

src/librustdoc/html/render/print_item.rs

There can be one method right? If so, the s at the end of methods should be conditional.

Also, can you add backticks around each method name please? Makes it easier to read it in a console.

There can be one method right? If so, the s at the end of methods should be conditional.

No, there are always at least two methods.

Oh indeed. So my first comment can be ignored. Remains the second one. ;)

You need to add this into ayu.css as well.

It was already there though. Adding .stab.must_implement{} fixed the issue, seems like a bug in the checker...

No, the rule isn't the same so to speak. They needed to be all split (hence why it was unhappy). The joy of CSS. :)

GuillaumeGomez · 2022-07-19T17:08:06Z

Looks all good to me. Please add the missing CSS rule in the ayu theme and it should be good to go!

☔ The latest upstream changes (presumably #99598) made this pull request unmergeable. Please resolve the merge conflicts.

WaffleLapkin · 2022-07-24T15:53:52Z

Can someone explain why the tests fail/how to fix them? I don't really get gui tests 😅

GuillaumeGomez · 2022-07-24T19:00:18Z

All the GUI tests are failing because there is a change in the body width. Basically, you broke the layout. 😆
