Rust 编译错误

    }

}

}

fn  main() {

 roomList.insert(String::from("1") , RoomServer { BattleTime: 10.5, sceneId: String::from("852963") });

 roomList.insert(String::from("2") , RoomServer { BattleTime: 10.7, sceneId: String::from("741852") });

 roomList.insert(String::from("3") , RoomServer { BattleTime: 10.6, sceneId: String::from("753159") });

 for  item  in  roomList.iter() {

 println!("{}", item.value().sceneId);

    }

 let  v  =  roomList.get("1");

 let  binding  =  v.unwrap();

 let  roomServer  =  binding.value();

 let  info  =  roomServer.getOneBronAndCamp();

 loop {

    }

}

编译出错，哪位大佬帮忙看一下么
