How to configure rust-analyzer using vim.lsp.config?

[shmerl]

Since neovim 0.11, there is a way to configure LSP without using nvim-lspconfig plugin, with the help of vim.lsp.config API (according to this post).

An example for clangd is like this:

vim.lsp.config.clangd = {
  cmd = { 'clangd', '--background-index' },
  root_markers = { 'compile_commands.json', 'compile_flags.txt' },
  filetypes = { 'c', 'cpp' },
}

vim.lsp.enable({'clangd'})

Is there some documentation or example of how this can be done for Rust with rust-analyzer?

Thank you!

I think something like this would work:

vim.lsp.config('rust_analyzer', {
  settings = {
    ['rust-analyzer'] = {
      cargo = { targetDir = true },
      check = { command = 'clippy' },
      inlayHints = {
        bindingModeHints = { enabled = true },
        closureCaptureHints = { enabled = true },
        closureReturnTypeHints = { enable = 'always' },
        maxLength = 100,
      },
      rustc = { source = 'discover' },
    }
  },
}

I'll suplement example settings for clients like nvim or helix to our docs
