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?

先閱讀 PageIterator 的實作及其 callback 處理方式，接著將要求的行為與 issue 中的 .NET 範例進行比較。判斷暫停的反覆運算如何公開完成狀態，並從目前位置繼續；當 SDK 的行為及其使用方式獲得明確定義與驗證後，即表示完成。
