encode method

@override Uint8List encode(int protocolVersion, MessageEncoding encoding)

Encode message to bytes

Implementation

@override
Uint8List encode(int protocolVersion, MessageEncoding encoding) {
  final bytes = <int>[];

  // Command that was rejected (variable length string)
  final cmdUtf8 = utf8.encode(cmd);
  VarInt.write(bytes, cmdUtf8.length);
  bytes.addAll(cmdUtf8);

  // Code indicating why the command was rejected (1 byte)
  bytes.add(code.value);

  // Human readable reason string (variable length string)
  final reasonUtf8 = utf8.encode(reason);
  VarInt.write(bytes, reasonUtf8.length);
  bytes.addAll(reasonUtf8);

  // Hash (only for block/tx rejections, 32 bytes)
  if (hash != null) {
    bytes.addAll(hash!.bytes);
  }

  return Uint8List.fromList(bytes);
