示例3: DecodeTKey

// DecodeTKey returns a label and block index bytes from a label block RLE key.
// The block index bytes are returned because different block indices may be used (e.g., CZYX),
// and its up to caller to determine which one is used for this particular key.
func DecodeTKey(tk storage.TKey) (label uint64, block dvid.IZYXString, err error) {
	ibytes, err := tk.ClassBytes(keyLabelBlockRLE)
	if err != nil {
		return
	}
	label = binary.BigEndian.Uint64(ibytes[0:8])
	block = dvid.IZYXString(ibytes[8:])
	return
}
