Rust LSP Setup For Neovim 0.10

this code is not currnetly in place. I'm working with my main config file while I try to figure things out.

~/.config/nvim/after/plugin/rust-lsp-setup.lua

-- vim.lsp.start({
 -- name = 'Rust Analyzer',
  -- cmd = {'rust-analyzer'},
  -- root_dir = vim.fs.dirname(vim.fs.find({'Cargo.toml'}, { upward = true })[1]),
-- })

-- end of line --
