Rust: 格式填充操作符

  fn main() {
     let score1 = 100;
     let score2 = 1000;
     let score3 = 10000;

     println!("{:>5}", score1);
     println!("{:>5}", score2);
     println!("{:>5}", score3);

     let padded = "padded";
     println!("[{:^10}]", padded);
     let title = "SCORES";

     let player1 = "first player:";
     let player2 = "second player:";
     let player3 = "third player:";

     let score1 = 100;
     let score2 = 1000;
     let score3 = 10000;

     println!("{:_^20}", title);
     println!("{:<14} {:>5}", player1, score1);
     println!("{:<14} {:>5}", player2, score2);
     println!("{:<14} {:>5}", player3, score3);

     thread::sleep(Duration::from_millis(500000));
