mason-lspconfig troubleshooting                          *rustaceanvim.mason*

This plugin supports automatically detecting mason.nvim codelldb installations,
but not rust-analyzer.
The main reason for this choice is that it mason.nvim installations of rust-analyzer
will most likely have been built with a different toolchain than your project,
leading to inconsistencies and possibly subtle bugs.

If you want to use a mason.nvim installation anyway, you can do so by specifying
the `server.cmd` setting (see |rustaceanvim.config| and |RustaceanLspClientOpts|):
>lua
  vim.g.rustaceanvim = {
    server = {
      cmd = function()
	local mason_registry = require('mason-registry')
	local ra_binary = mason_registry.is_installed('rust-analyzer') 
	  -- This may need to be tweaked, depending on the operating system.
	  and mason_registry.get_package('rust-analyzer'):get_install_path() .. "/rust-analyzer"
	  or "rust-analyzer"
	return { ra_binary } -- You can add args to the list, such as '--log-file'
      end,
    },
  }
<
Note that mason-lspconfig.nvim, when configured to ensure rust-analyzer is installed,
assumes you are using the `nvim-lspconfig.rust_analyzer` client.
Some Neovim distributions will automatically call the client's `setup`
function, resulting in a conflict with this plugin.

General approach to prevent mason-lspconfig from setting up
`lspconfig.rust_analyzer`:

>lua
  require('mason-lspconfig').setup_handlers {
    ['rust_analyzer'] = function() end,
  }
<

Using LazyVim:

>lua
  {
    'neovim/nvim-lspconfig',
    opts = {
      setup = {
        rust_analyzer = function()
          return true 
        end,
      },
    },
  }
