Scan.fromResult constructor

Scan.fromResult(List<RespType>? result)

Implementation

factory Scan.fromResult(List<RespType<dynamic>>? result) {
  int _cursor = 0;
  List<String> _keys = [];

  if (result != null && result.length == 2) {
    final element1 = result[0] as RespBulkString;
    final payload1 = element1.payload;
    if (payload1 != null) {
      _cursor = int.parse(payload1);
    }

    final element2 = result[1] as RespArray;
    final payload2 = element2.payload;
    if (payload2 != null) {
      _keys = payload2
          .cast<RespBulkString>()
          .map((e) => e.payload!)
          .toList(growable: false);
    }
  }

  return Scan(
    cursor: _cursor,
    keys: _keys,
  );
}
