You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: main.rs
    path of file: ./repos/rust-bible/part1/super_player/src
    
    the code of the file until where you have to start completion: // 使用关键字 use 将特征导入需要调用特征的模块的作用域中
use crate::car::Vehicle;
use car::Car;
use media::Playable;

mod car;
mod media; // 这句是定义media模块

struct Tesl {
    model: String,
  
    
fn main() {
    let a = Audio("audio test".to_string());
    let v = Video("mp3 test".to_string());
    a.play();
    v.play();

    // 直接调用关联方法
    Audio::pause();

    let tesl = Tesl::new("model 2", 2021);
    println!(
        "tesl model:{},date:{},price:{}",
        tesl.model(),
        tesl.release_date,
        tesl.get_price()
    );
}
