Highlight crate links as normal links with --enable-index-page

[camelid]

Rustdoc highlights most links in blue, for example module links:

But it does not highlight the links on the docs index page:

Generally links are highlighted in blue (or some other color) on websites and the rest of Rustdoc highlights links so it would be more consistent to highlight these links.

@rustbot modify labels: C-bug C-enhancement T-rustdoc

Where did you find that link?

[camelid]

The index page is https://doc.rust-lang.org/nightly/nightly-rustc/ and the page that shows the modules is https://doc.rust-lang.org/nightly/nightly-rustc/rustc_ast/index.html.

@jyn514 Do you know how to get to the index page (https://doc.rust-lang.org/nightly/nightly-rustc/) with docs for other crates? I can't seem to find the "List of all crates" in docs for other projects.

[jyn514]

I don't think this is actually generated by rustdoc. This looks like bootstrap is passing --index-page.

[jyn514]

In which case this should be a feature request for bootstrap, not a bug report for rustdoc.

[camelid]

Hmm, but it's generated by Rustdoc here:

rust/src/librustdoc/html/render/mod.rs

Lines 1062 to 1072 in 9d606d9

	let content = format!(
	"<h1 class='fqn'>\
	<span class='in-band'>List of all crates</span>\
	</h1><ul class='mod'>{}</ul>",
	krates
	.iter()
	.map(|s| {
	format!("<li><a href=\"{}index.html\">{}</li>", ensure_trailing_slash(s), s)
	})
	.collect::<String>()
	);

Oh interesting. It's still not on by default, you need to pass --enable-index-page, but it's definitely a rustdoc issue.
