Implementation

Future<Result<T2>> tryAsResultAsync<T2>(FutureOr<T2?> Function() f) async {
  try {
    var callResult = await f();
    return callResult == null
        ? Err<T2>(StateError('async function returned null'))
        : Ok(callResult);
  } catch (e) {
    return Err(StateError('$e'));
