encode static method

Uint8List encode(dynamic data)

Encodes data using RLP encoding.

Supported types:

• Uint8List - encoded as bytes
• String - encoded as UTF-8 bytes
• int - encoded as big-endian bytes
• BigInt - encoded as big-endian bytes
• List - encoded as RLP list
• null - encoded as empty bytes

Example:

RLP.encode('dog'); // [0x83, 0x64, 0x6f, 0x67]
RLP.encode(['cat', 'dog']); // [0xc8, 0x83, 0x63, 0x61, 0x74, 0x83, 0x64, 0x6f, 0x67]

Implementation

static Uint8List encode(dynamic data) {
  if (data == null) {
    return _encodeBytes(Uint8List(0));
  }

  if (data is Uint8List) {
    return _encodeBytes(data);
  }

  if (data is List) {
    return _encodeList(data);
  }

  if (data is String) {
    return _encodeBytes(Uint8List.fromList(data.codeUnits));
  }

  if (data is int) {
    if (data == 0) {
      return _encodeBytes(Uint8List(0));
    }
    return _encodeBytes(BytesUtils.intToBytes(data));
  }

  if (data is BigInt) {
    if (data == BigInt.zero) {
      return _encodeBytes(Uint8List(0));
    }
    return _encodeBytes(BytesUtils.bigIntToBytes(data));
  }

  throw RlpException(
      'Unsupported type for RLP encoding: ${data.runtimeType}');
}
