Rust Programming By Example

Tetris struct

This type will be the one holding all the game's information:

• Game map
• Current level
• Score
• Number of lines
• The current tetrimino
• Some potential other information (such as a ghost, or the preview of the next tetrimino!)

Let's write down this type:

struct Tetris {
    game_map: Vec<Vec<u8>>,
    current_level: u32,
    score: u32,
    nb_lines: u32,
    current_piece: Option<Tetrimino>,
}

Once again, pretty simple. I don't think any additional information is required so let's continue!

Let's start by writing the new method for this new type:

impl Tetris {
    fn new() -> Tetris {
        let mut game_map = Vec::new();
        for _ in 0..16 {
            game_map.push(vec![0, 0, 0, 0, 0, 0, 0, 0, 0, 0]);
        }
        Tetris {
            game_map: game_map,
            current_level: 1,
            score: 0, nb_lines:  ...
