Rust Analyzer doesn't use settings given by nvim.

[hfytr]

So I am using neovim, and have configured rust-analyzer like this:

local servers = {
    rust_analyzer = {
        cmd = { 'rust-analyzer' },
        filetypes = { 'rust' },
        root_markers = { 'Cargo.toml', '.git', '.gitignore', 'Cargo.lock' },
        settings = {
            ['rust-analyzer'] = { cargo = { cfgs = { 'ssr', 'hydrate' } } },
        },
    },
}

for lsp, opts in pairs(servers) do
    vim.lsp.config[lsp] = opts
    vim.lsp.enable(lsp, true)
end

and checkhealth lsp shows everything as expected:

vim.lsp: Active Clients ~
- rust_analyzer (id: 1)
  - Version: 1.89.0-nightly (59aa1e8 2025-06-03)
  - Root directory: ~/docs/mgh/code/webapp/screenmap
  - Command: { "rust-analyzer" }
  - Settings: {
      ["rust-analyzer"] = {
        cargo = {
          cfgs = { "ssr", "hydrate" }
        }
      }
    }
  - Attached buffers: 2, 31, 19, 12, 18, 6

The problem is that my settings don't seem to be taking effect, as evidenced by the screenshot:

Also, here is a pastebin with my lsp log: https://pastebin.com/CSR1czfG
you will notice that nvim correctly transmits the settings, showing this is probably an RA issue: [ERROR][2025-06-11 15:05:18] ...p/_transport.lua:36 "rpc" "rust-analyzer" "stderr" '2025-06-11T15:05:18.556172496-04:00 INFO GlobalState::handle_event{event=Event::Lsp}: task queue len: 1\n2025-06-11T15:05:18.556209707-04:00 INFO GlobalState::handle_event{event=Event::Lsp}: updating config from JSON: {\n "cargo": {\n "cfgs": [\n "ssr",\n "hydrate"\n ]\n }\n}\n'

Did you try setting rust-analyzer.cargo.features to ["ssr"]?

This worked, thanks!
