No autocomplete for Tool Prelude attributes in VsCode.

[TmSalviano]

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.

If you mean completion for attributes such as #[rustfmt::skip], there is no autocomplete because nobody ever implemented it. The code responsible for completing attributes is here: https://github.com/rust-lang/rust-analyzer/blob/master/crates/ide-completion/src/completions/attribute.rs, if someone wants to work on this.

Thank you very much!
