[client(host = "http://127.0.0.1:3000", path = "/user")]

pub trait UserClient {

#[get(path = "/find_by_id/<id>")]
async fn find_by_id(&self, #[path] id: i64) -> ClientResult<Option<User>>;

#[post(path = "/new_user")]
async fn new_user(&self, #[json] user: &User) -> ClientResult<Option<String>>;

}

[tokio::main]

async fn main() { let user_client: UserClient = UserClient::new();

match user_client.find_by_id(12).await {
    Ok(option) => match option {
        Some(user) => println!("user : {}", user.name),
        None => println!("none"),
    },
    Err(err) => panic!("{}", err),
};
