No way to get to docs for previous versions of std

[plumenator]

Content Bug Report

Page(s) Affected

https://doc.rust-lang.org/std/index.html

What needs to be fixed?

Missing a drop down to select the version of std

Workaround

Edit the URL directly like so:

https://doc.rust-lang.org/<version>/std/index.html

Suggested Improvement

Like at docs.rs, it would be great if we could switch between versions of the documentation.

[plumenator]

Moved from rust-lang/www.rust-lang.org#965

[tesuji]

It does, for example https://doc.rust-lang.org/1.37.0/std/index.html

[plumenator]

Sorry, I meant to say that there's no way from the UI. One has to already know (or guess) the URL to access it

Updated to description with the workaround

This doesn't really belong in this repo either as rustdoc documents one crate at a time and doesn't know about other versions. docs.rs already does something like this for ecosystem crates, maybe that's something to look into for libstd too?

[plumenator]

I think it would be less of an issue if we could generate it locally with cargo. For std, the local docs send you to the website.

What are the uses of rustdoc for specific Rust version? Since Rust is really good at
keeping backward compatibility.

I think this is a duplicate of #44687 (RFC 1826 which includes a version selector) and #30062.

Closing in favor of #30062
