fn partition<A,B>(list: Vec<Result<A,B>>) -> (Vec<A>, Vec<B>) {
    let mut aa = vec!();
    let mut bb = vec!();
    for i in list {

            Ok(a) => aa.push(a),
            Err(b) => bb.push(b),
        };
    }
    (aa, bb)
}

fn main() {
  let rows_result: Vec<Result<String, i32>> =
      vec!(Ok("abc".to_string()), Err(123));

  let (rows, row_parse_errors): (Vec<String>, Vec<i32>) =
      partition(rows_result);

  assert_eq!(rows, vec!("abc".to_string()));
  assert_eq!(row_parse_errors, vec!(123));
