@rust-lang/rustdoc works too. ;)

(Just wanted to ping you as the reviewer of #73771 😁) Right, there were a bunch of people who commented on that PR

[GuillaumeGomez]

Absolutely. ;)

well that's odd.

[tesuji]

std/primitive.slice.html has broken links because after this PR, it displays Concat trait implementations.
Before that, they are hidden.

std/primitive.u64.html has a broken link for impl ReaderOffset for usize, which was hidden by #73771.

[jyn514]

I don't understand, sorry. What do the broken links have to do with the new implementors being shown? I don't see any links to #tymethod.from_u64 or ::from_u64 in the source code.

[tesuji]

To reproduce the issue, one has to build with --stage 1.

For usize, the "Read more" link is broken: http://0.0.0.0:8000/std/primitive.usize.html#tymethod.from_u64

For Concat trait under std/primitive.slice: note the ../../. It is kind of problems that intra-docs link trying to solve.

/// Implementation of [`[T]::concat`](../../std/primitive.slice.html#method.concat)

[jyn514]

Got it, thanks. The broken primitive.slice.html link can't be fixed until #63351 is.

I took a look at #from_u64 - they don't actually have a link there:

So it seems like rustdoc itself is generating invalid links 🤦

Since this is intended to be backported to beta, I think we should just whitelist the broken links for now. If you want to try and fix the issues in a follow-up commit that would be great :) but I think only the revert should be backported.

[tesuji]

Another candidate: #76571

[Mark-Simulacrum]

r? @jyn514 -- seems like you have a better handle than I on these things

I'm going to close this: I think #76571 is a better candidate for backport and we can always re-open it against beta if the rustdoc team decides they don't want to backport 76571.
