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]
