data Shift {}

impl Codec<i64> for Shift {
  static fn encode(x: &i64, w: &var Encoder) -> () | EncodeError { w.writeI64(x + 1) }
  static fn decode(r: &var Decoder) -> i64 | DecodeError { r.readI64()? - 1 }
  static fn schema() -> Schema => Schema.of("int64")
}

fn main() io {
  print(Shift.schema().proto)
}
