这是基于上面的示例。在Rust方面，您需要一个​PathResolver​的实例，您可以从​App​和​AppHandle​中获取：

tauri::Builder::default()
  .setup(|app| {
    let resource_path = app.path_resolver()
      .resolve_resource("lang/de.json")
      .expect("failed to resolve resource");

    let file = std::fs::File::open(&resource_path).unwrap();
    let lang_de: serde_json::Value = serde_json::from_reader(file).unwrap();

    println!("{}", lang_de.get("hello").unwrap()); // This will print 'Guten Tag!' to the terminal

    Ok(())
  })

#[tauri::command]
fn hello(handle: tauri::AppHandle) -> String {
   let resource_path = handle.path_resolver()
      .resolve_resource("lang/de.json")
      .expect("failed to resolve resource");

    let file = std::fs::File::open(&resource_path).unwrap();
    let lang_de: serde_json::Value = serde_json::from_reader(file).unwrap();

    lang_de.get("hello").unwrap()
}
