示例1: TestStringMeaning

	var xx [4]interface{}
	xx[0] = &struct {
		X string
	}{"xx0"}
	xx[1] = &struct {

	}{"xx1"}
	xx[2] = &struct {
		X []byte
	}{[]byte("xx2")}
	xx[3] = &struct {
		X []byte `datastore:",noindex"`
	}{[]byte("xx3")}

	indexed := [4]bool{
		true,
		false,
		false, // A []byte is always no-index.
		false,
	}
	want := [4]pb.Property_Meaning{
		pb.Property_NO_MEANING,
		pb.Property_TEXT,
		pb.Property_BLOB,
		pb.Property_BLOB,
	}

	for i, x := range xx {
		c := make(chan Property, 1)
		err := SaveStruct(x, c)
		if err != nil {
			t.Errorf("i=%d: SaveStruct: %v", i, err)
