Pattern matching in rust:

  match x {
      <cond1> => <expr1>,
      <cond2> => <expr2>,
      <cond3> => <expr3>,
      _ => <expr>,
  } 

  let message = match maybe_digit {
      Some(x) if x < 10 => process_digit(x),
      Some(x) => process_other(x),
      None => panic!(),
  };

Seems useful. Python's getting match soon too!
