Correct std::prelude comment

[kadiwa4]

(Read the changed file first for context.)

First, alloc has no prelude.

Second, the docs for v1 don't matter since the prelude module already has all the doc links. The rust_2021 module for instance also doesnt have a convenient doc page. However as I understand glob imports still cant be used because the items dont have the same stabilisation versions.

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

• Stabilizing library features
• Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
• Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
• Changing public documentation in ways that create new stability guarantees
• Changing observable runtime behavior of library APIs

Looks like the alloc prelude was removed in 8007dfa, good catch.

Second, the docs for v1 don't matter since the prelude module already has all the doc links. The rust_2021 module for instance also doesnt have a convenient doc page. However as I understand glob imports still cant be used because the items dont have the same stabilisation versions.

I don't think this is accurate? 2021 has a page right here: https://doc.rust-lang.org/std/prelude/rust_2021/index.html
and v1 has a page as well: https://doc.rust-lang.org/std/prelude/v1/index.html
so I think the old comment was correct at least for that part.

Thanks for reviving my PRs!

I don't think this is accurate? 2021 has a page right here: https://doc.rust-lang.org/std/prelude/rust_2021/index.html

What I meant was that that page is a pain to navigate and people are probably gonna use the std::prelude docs instead. Because the std::prelude docs are generally more convenient than the v1 ones, it doesnt matter if that module page shows a complete list or only shows a glob import.

But I can revert that change if you disagree with it

[jyn514]

I'd like to revert that change, yes, I think it's important for the v1 links to point to std even if it's rare to look at them.

Happy to approve when that's done :)

Thanks!
