use tauri::{CustomMenuItem, SystemTrayMenu, SystemTrayMenuItem};

创建 ：SystemTrayMenu

// 这里 `"quit".to_string()` 定义菜单项 ID，第二个参数是菜单项标签。
let quit = CustomMenuItem::new("quit".to_string(), "Quit");
let hide = CustomMenuItem::new("hide".to_string(), "Hide");
let tray_menu = SystemTrayMenu::new()
  .add_item(quit)
  .add_native_item(SystemTrayMenuItem::Separator)
  .add_item(hide);
