use std.ser { Codec, Encoder, Decoder, Schema, encode, decode, hex, EncodeError, DecodeError }

data Raw {}

impl Codec<bytes> for Raw {
  static fn encode(x: &bytes, w: &var Encoder) -> () | EncodeError { w.writeBytes(x) }
  static fn decode(r: &var Decoder) -> bytes | DecodeError { r.readBytes() }
  static fn schema() -> Schema => Schema.of("bytes")
}

data Wrap {
  @codec(Raw) blob: bytes
}

fn main() io {
  let b = encode(&Wrap{ blob: b"\x01\x02\x03" })!
  print("{decode<Wrap>(&b)!.blob.len()}")
}
