Use intra-doc links in core::iter module#74300

tesuji · 2020-07-13T16:28:48Z

This will make core::iter doc depend less on std doc.

This would result in dead links in std due to #65983, also see #73579 (comment) where I personally first noticed this problem.

src/libcore/iter/traits/accum.rs

Does this not have an equivalent?

This fragment link is fine as the sum method referred belongs to Sum trait.

This is #51284, which is a project all on its own. If @lzutao checked that it works I'm fine with it.

Can this not be Sum::sum or Self::sum?

Is it documented in Intra RFC? That's new to me!

tesuji · 2020-07-14T02:38:54Z

@lcnr I don't quite sure there are any broken links as linkchecker doesn't warn.
Also I don't use cross-crate links (I think), only crate:: prefix links.
cc @jyn514 to make sure.

jyn514 · 2020-07-14T03:06:50Z

I'm pretty sure core is re-exported as part of std, so that could break things. You should check locally to be sure.

jyn514 · 2020-07-14T03:07:30Z

As a side note, #73101 is almost ready to be merged, maybe 1 or 2 more weeks.

tesuji · 2020-07-14T04:34:21Z

Checked locally and ran linkchecker. I don't see any broken links
in both std and core.

lcnr · 2020-07-14T08:14:05Z

tesuji · 2020-07-14T08:16:11Z

~~Pardon me?~~
Edit: Oh, I see it now. Option is not linked. I will see what I can do to fix the links.

tesuji · 2020-07-14T11:22:14Z

After experimenting, I observed two things:

Replacing [`Option`] in core::iter with crate::option::Option broke the link.
Letting rustdoc handle Option link (no manually specify link), rustdoc doesn't make link or warn about that.

The broke links are detected by linkchecker. I don't know if there are more empty-links,
but this PR shouldn't broke links.

This would result in dead links in std due to #65983, also see #73579 (comment) where I personally first noticed this problem.

#73101 just landed so this should be fixed once you rebase 😄 You'll need to use x.py doc --stage 1 to get the changes.

tesuji · 2020-07-17T06:00:32Z

Rebased. Looks like stage1 rustdoc fixes the Option link in core::iter .

Looks great! It's good to see how this is used in the wild, it gave me ideas for more features to add 😆 I had one small nit but everything else is informative or notes to myself.

This is #62834. This is a good workaround in the meantime though.

But why not just use Option rather than Option<T>?

Option<T> seems to be clearer for beginners/first readers of Iterator.

We could use Option<T> in the book, but I don't think beginners get here easily.

jyn514 · 2020-07-17T11:18:28Z

src/libcore/iter/traits/iterator.rs

I've seen this quite a few times now, maybe it would be a good feature for intra-doc links to add, same as #62834?

jyn514 · 2020-07-17T11:27:27Z

ran linkchecker. I don't see any broken links

#74185 (comment). Maybe we should add deny(intra_doc_link_resolutuion_failure) now that cross crate re-exports work?

Because the old one is harder to read and confuse typing checkers.

jyn514 · 2020-07-17T14:26:29Z

Maybe we should add deny(intra_doc_link_resolutuion_failure) now that cross crate re-exports work?

It turns out this will be on by default starting in #71670. But it doesn't hurt to have it on now.
