  1. @override
Resolvable<T> ifErr(

    2. Err<T> err
    )
)
override

Implementation

@override
Resolvable<T> ifErr(
  @noFutures void Function(Async<T> self, Err<T> err) noFutures,
) {
  return Async(() async {
    final awaitedValue = await value;
    return switch (awaitedValue) {
      Ok() => this,
      Err<T> err => Sync(() {
        noFutures(this, err);
        return awaitedValue;
      }).flatten(),
    };
  }).flatten();
}
