[Bug]: Rust `#![attributes]` are not highlighted

[mrjones2014]

Your minimal.lua config

local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "--single-branch",
    "https://github.com/folke/lazy.nvim.git",
    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  {
    "olimorris/onedarkpro.nvim",
    opts = {
      -- Your OneDarkPro config goes here

    config = true
  },

No response

Describe the bug

For example, this is not highlighted, which I typically put at the top of any lib.rs file:

#![deny(clippy::all, clippy::pedantic, rust_2018_idioms, clippy::unwrap_used)]

But kind without the ! are highlighted correctly:

#[derive(Debug)]

Screenshot:

Looks like it needs an additional LSP semantic token highlight.

Reproduce the bug

1. cargo new example-crate
2. Edit main.rs to have the following contents

#![deny(clippy::all, clippy::pedantic, rust_2018_idioms, clippy::unwrap_used)]

#[derive(Debug)]
enum Error {
  MyError,
}

fn main() {}

Final checks

• [X] I have made sure this issue exists in the latest version of the plugin
• [X] I have tested with the minimal.lua config file above and still get the issue
• [X] I have confirmed that Treesitter is working correctly by running :checkhealth treesitter
• [X] If related to semantic tokens, I have checked that my LSP server supports them
• [X] I have made sure this is not a duplicate issue

I notice this isn't coloured in the original VS Code theme either:

...which seems a bit of a miss.

How does this look?

I used these highlights:

["@lsp.type.builtinAttribute.rust"] = { link = "Function" },
["@lsp.type.attributeBracket.rust"] = { link = "@punctuation.bracket.rust" },
["@lsp.type.generic.rust"] = { fg = theme.palette.red, style = config.styles.variables },

That looks great! Should I copy those to my config or will you be adding those to the default Rust highlights?

[olimorris]

I've merged into main! Thanks for raising...looks so much better.
