Dann nimmt es 🤖 die erste erledigte Aufgabe (sagen wir, unsere „Langsam-Datei“ 📝) und bearbeitet sie weiter.

Das „Warten auf etwas anderes“ bezieht sich normalerweise auf <abbr title="Input and Output – Eingabe und Ausgabe">I/O</abbr>-Operationen, die relativ „langsam“ sind (im Vergleich zur Geschwindigkeit des Prozessors und des Arbeitsspeichers), wie etwa das Warten darauf, dass:

* die Daten des Clients über das Netzwerk empfangen wurden

	var zb0001 uint32
	zb0001, err = dc.ReadArrayHeader()
	if err != nil {
		err = msgp.WrapError(err)
		return
	}
	if zb0001 != uint32(sizeLastElemMarker) {
		err = msgp.ArrayError{Wanted: uint32(sizeLastElemMarker), Got: zb0001}
		return
	}
	for za0001 := range z {
		var field []byte
		_ = field
		var zb0002 uint32
		zb0002, err = dc.ReadMapHeader()
		if err != nil {

			// Test if result matches.
			t.Errorf("Requested mismatch, want %v, got %v", Requested(test.Header), got)
		}
		got = got && S3KMS.IsRequested(test.Header)
		if got != test.Expected {
			t.Errorf("SSE-KMS: Test %d: Wanted %v but got %v", i, test.Expected, got)
		}
	}
	for i, test := range s3IsRequestedTests {
		_, got := IsRequested(test.Header)
		if Requested(test.Header) != got {
			// Test if result matches.

...but continue reading below to see how to overcome that.

## Return Type and Data Filtering

Let's continue from the previous example. We wanted to **annotate the function with one type**, but we wanted to be able to return from the function something that actually includes **more data**.

          if (comparator == null) {
            // A sorted spliterator with no comparator is already using natural order.
            // (We could probably find a way to avoid rawtypes here if we wanted.)
            @SuppressWarnings({"unchecked", "rawtypes"})
            Comparator<? super E> naturalOrder =
                (Comparator<? super E>) Comparator.<Comparable>naturalOrder();
            comparator = naturalOrder;

          if (comparator == null) {
            // A sorted spliterator with no comparator is already using natural order.
            // (We could probably find a way to avoid rawtypes here if we wanted.)
            @SuppressWarnings({"unchecked", "rawtypes"})
            Comparator<? super E> naturalOrder =
                (Comparator<? super E>) Comparator.<Comparable>naturalOrder();
            comparator = naturalOrder;
