No autocomplete for Tool Prelude attributes in VsCode.

Thank you all for putting in the work and effort to make Rust the best language ever!

I am having a problem with the rust_analyzer tool in VsCode. There is no autocomplete for the Tool Prelude attributes. I was incapable of finding answers on google.

The Tool Prelude is imported. I already tested #[rustfmt::skip] for example and it's working just fine

The only problem is the autocomplete. Here is my rust analyzer configurations in VsCode:

  "rust-analyzer.inlayHints.lifetimeElisionHints.enable": "always",
  "rust-analyzer.inlayHints.reborrowHints.enable": "always",
  "rust-analyzer.cargo.features": "all",

I am pretty confident this is not a VsCode problem because the intellisense seems to be working perfectly well for everything else. I suspect it is a rust_analyzer configuration issue, since rust_analyzer is also working perfectly fine for everything else as well.

I don't really know if this is a VsCode problem or a rust_analyzer problem. I don't even know if it is a problem thanks to the only clue i got from The Rust Prelude:

"When a tool is not in use, the tool’s attributes are accepted without a warning. When the tool is in use, the tool is responsible for processing and interpretation of its attributes."

Is this even a problem? I am completely lost and any help would be deeply appreciated.

Start by reproducing the missing autocomplete in VSCode with rust_analyzer, using the Tool Prelude attribute example #[rustfmt::skip] from the report. Check whether completion is expected for imported tool attributes and compare it with the existing autocomplete behavior for other Rust attributes. Done means the behavior is explained and, if confirmed as a bug, covered by an appropriate rust_analyzer test.
