26.7.29 Slide view [range.slide]

26.7.29.1 Overview [range.slide.overview]

slide_view takes a view and a number N and produces a view whose element is a view over the through elements of the original view.
If the original view has fewer than N elements, the resulting view is empty.
The name views​::​slide denotes a range adaptor object ([range.adaptor.object]).
Given subexpressions E and N, the expression views​::​slide(E, N) is expression-equivalent to slide_view(E, N).
[Example 1: vector v = {1, 2, 3, 4}; for (auto i : v | views::slide(2)) { cout << '[' << i[0] << ", " << i[1] << "] "; // prints [1, 2] [2, 3] [3, 4] } — end example]
