How to Set Up Neovim for Rust Development

Set up Neovim for Rust by installing the nvim-lspconfig plugin and configuring rust-analyzer with cargo build scripts and procMacro support. Add the following Lua configuration to your Neovim init.lua file to enable the language server and inlay hints:

local lspconfig = require('lspconfig')

lspconfig.rust_analyzer.setup({
  on_attach = function(client, bufnr)
    vim.lsp.inlay_hint.enable(true, { bufnr = bufnr })
  end,
  settings = {
    ['rust-analyzer'] = {
      cargo = {
        buildScripts = { enable = true }
      },
      procMacro = {
        enable = true
      }
    }
  }
})

Restart Neovim to apply the changes.

Setting up Neovim for Rust Development connects your editor to the Rust language server, providing features like code completion and error checking as you type. It functions like a spell checker in a word processor but focuses specifically on Rust code logic and syntax. You use this setup whenever writing or editing Rust files to catch mistakes instantly.
