Documentation for std doesn't open correctly anymore

[CryZe]

If I run "Rust Analyzer: Open docs under cursor" on any std or core symbol, it opens some invalid docs.rs page, such as this one for HashMap:

https://docs.rs/STD/0.1.0/std/collections/hash/map/struct.HashMap.html

[CryZe]

The reason seems to be that #![doc(html_root_url = "...")] is not specified for std / core / ... anymore, as they hardcoded "nightly" into that URL before.

rust-lang/rust#84942

The reason seems to be that #![doc(html_root_url = "...")] is not specified for std / core / ... anymore,

It is specified, just as an argument and not as a hard-coded attribute.

That value is only available through metadata, not the source itself, but you might be able to copy the logic and parse the output of rustc --version.

Another example:

• Hover mouse cursor over type in your code in VSCode - a popup with docs appears
• Click on the link named associated type
• Page https://docs.rs/STD/0.1.0/std/reference/items/associated-items.html#associated-types opens, you get "The requested resource does not exist"

Used SW:

• VSCode 1.61.1
• rust-analyzer v0.2.776
