constexpr explicit slide_view ( V base, ranges:: range_difference_t < V > n ) ;
(since C++23)

Constructs a slide_view initializing the underlying data members:

  • move construct the underlying view base_ with std :: move ( base ) ,
  • the "window size" n_ with n .

Parameters

base - the source view
n - the "sliding window" size

Example

Run this code 
#include <algorithm>
#include <iostream>
#include <ranges>
 
int main()
{
    const auto source = {1, 2, 3, 4};
 
    auto slide = std::views::slide(source, 3);
 
    std::ranges::for_each(slide, [](std::ranges::viewable_range auto&& w)
    {
        std::cout << '[' << w[0] << ' ' << w[1] << ' ' << w[2] << "]\n";
    });
}

Output: 

[1 2 3]
[2 3 4]
