Here string name of type of ruler item:

If this key exists its value is true. This key exists only for current page.

If a piece is located outside of array then returns true else false. It can happen when page_number is <= 0 or page_number is more than a maximal possible page number for this data array. If "outside" returned a true then "start", "end" and "size" methods will return 0 and "ruler" returns an empty array.
