decodeIndexedListBytes<T> static method

List<T> decodeIndexedListBytes<T>(Uint8List framed, T readItem(RecordReader r))

Decodes an indexed list ([4B count][8B×n offsets][items]) eagerly.

The web copies the framed buffer out of the module heap anyway, so a lazy view buys nothing — decode all items in one pass.

Implementation

static List<T> decodeIndexedListBytes<T>(
  Uint8List framed,
  T Function(RecordReader r) readItem,
) {
  final header = RecordReader.fromFramedBytes(framed);
  final count = header.readInt32();
  final offsets = List<int>.generate(count, (_) => header.readInt(), growable: false);
  return List<T>.generate(
    count,
    (i) => readItem(RecordReader.fromFramedBytes(framed, offsets[i])),
    growable: false,
  );
}
