SurralDB响应采取方法不起作用

我正在学习Rust和SurralDB,并试图查询用户,但我遇到了一个奇怪的错误。

这是代码:

#[post("/register")]
async fn register_user_handler(
    body: web::Json<RegisterUserSchema>,
    data: web::Data<AppState>,
) -> impl Responder {
    let result = data
        .db
        .query("SELECT * from users where email = $email LIMIT 1")
        .bind(("email", &body.email))
        .await
        .unwrap();

    println!("From here: {:#?}", result.take(0));  // <------- This is the error line

    let uuid_id = Uuid::new_v4();

    let user = User {
        _id: uuid_id.to_string(),
        name: body.name.to_owned(),
        username: body.username.to_owned(),
        email: body.email.to_owned().to_lowercase(),
        password: "".to_string(),
        provider: "".to_string(),
        age: None,
        phone: "".to_string(),
        photo: "".to_string(),
        location: "".to_string(),
    };

    let new_user: Result<Vec<Option<User>>, Error> = data.db.create("users").content(user).await;

    if new_user.is_err() {
        println!("{:#?}", new_user);
    }

    println!("{:#?}", new_user);

    let json_response = serde_json::json! ({
        "status": "success".to_string(),
    });

    HttpResponse::Ok().json(json_response)
}

我得到了这个错误,这根本没有任何意义,因为它在文档和我看到的所有示例中都很好。我在谷歌上搜索了这个错误,但一无所获。我尝试了ChatGPT,但还是出现了同样的错误。

我在谷歌上搜索了这个错误,查看了文档和一些示例,发现实现没有任何差异。我问了ChatGPT,它给了我同样的例子。
