Reminder that neovim is completely free, you can modify the editor using Lua, it has a renaissance of new awesome plugins, LSP support for the official Rust LSP server, and as a system developer you can run it on a target device or quickly switch between a serial console and your editor using tmux. Plus, you can easily add new LLM integrations or wrap tools in about a half an hour of hacking. My neovim setup is easily 10x more productive than RustRover.
