Performs iterator arithmetic.

1,2) Equivalent to: auto r = i; r += n; return r;.

3) Equivalent to: auto r = i; r -= n; return r;.

4) Let current_ and last_ele_ be the underlying iterators to the begin and end of the sliding window, respectively. Equivalent to:

• return x.last_ele_ - y.last_ele_;, if last_ele_ is present. Otherwise,
• return x.current_ - y.current_;.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when slide_view::iterator<Const> is an associated class of the arguments.

Parameters

i, j	-	the iterators
n	-	position relative to current location

Return value

1,2) An incremented iterator.

3) A decremented iterator.

4) A distance between given iterators.
