これはRustで書かれたスネークゲームのスターターコードです：

```
use std::thread;
use std::time::Duration;
use termion::clear;
use termion::cursor;
use termion::raw::IntoRawMode;

struct Snake {
    x: i32,
    y: i32,
}

impl Snake {
    fn new() -> Self {
        Snake { x: 0, y: 0 }
    }

    fn move_left(&mut self) {
        self.x -= 1;
    }

    fn move_right(&mut self) {
        self.x += 1;
    }

    fn move_up(&mut self) {
        self.y -= 1;
    }

    fn move_down(&mut self) {
        self.y += 1;
    }
}

fn main() {
    let stdout = std::io::stdout().into_raw_mode().unwrap();
    let mut snake = Snake::new();

    loop {
        println!("{}{}O", cursor::Goto(snake.x, snake.y), clear::CurrentLine);
        thread::sleep(Duration::from_millis(100));
        snake.move_right();
    }
}
```
このコードでは、termionライブラリを使用してターミナルと対話し、ヘビを表示します。Snake構造体がヘビを表し、move_left、move_right、move_up、move_downメソッドがヘビの位置を変更します。ゲームのメインループでは、表示を更新し、ヘビを右に動かします。このコードを修正して、ユーザー入力、食べ物、衝突検出などの機能を追加し、本格的なスネークゲームを作ることができます。
Here's some starter code for a snake game written in Rust:

```
use std::thread;
use std::time::Duration;
use termion::clear;
use termion::cursor;
use termion::raw::IntoRawMode;

struct Snake {
    x: i32,
    y: i32,
}

impl Snake {
    fn new() -> Self {
        Snake { x: 0, y: 0 }
    }

    fn move_left(&mut self) {
        self.x -= 1;
    }

    fn move_right(&mut self) {
        self.x += 1;
    }

    fn move_up(&mut self) {
        self.y -= 1;
    }

    fn move_down(&mut self) {
        self.y += 1;
    }
}

fn main() {
    let stdout = std::io::stdout().into_raw_mode().unwrap();
    let mut snake = Snake::new();

    loop {
        println!("{}{}O", cursor::Goto(snake.x, snake.y), clear::CurrentLine);
        thread::sleep(Duration::from_millis(100));
        snake.move_right();
    }
}
```
This code uses the termion library to interact with the terminal and display the snake. The Snake struct represents the snake, and its move_left, move_right, move_up, and move_down methods change its position. The main loop of the game updates the display and moves the snake to the right. You can modify the code to add more functionality, such as user input, food, and collision detection, to make a full-fledged snake game.
