Unclear how to resume iterating with `PageIterator` if the callback returns `False`

In other SDKs, the iterator class typically has a Resume method to restart the iteration where it left off, and a corresponding State property to check if the iterator has completed or not. For example, in .NET:

var pageIterator = PageIterator<Message, MessageCollectionResponse>
    .CreatePageIterator(
        graphClient,
        messages,
        (msg) =>
        {
            Console.WriteLine(msg.Subject);
            count++;
            // If we've iterated over the limit,
            // stop the iteration by returning false
            return count < pauseAfter;
        });

await pageIterator.IterateAsync();

while (pageIterator.State != PagingState.Complete)
{
    Console.WriteLine("Iteration paused for 5 seconds...");
    await Task.Delay(5000);
    // Reset count
    count = 0;
    await pageIterator.ResumeAsync();
}

Is there a way to do this in this SDK?

まず PageIterator の実装とその callback 処理を読み、次に要求された動作を issue の .NET 例と比較します。停止した反復処理で完了状態を公開し、現在の位置から再開する方法を判断します。SDK の動作とその使用方法が明確に定義され、検証されれば完了です。
