adjacent_transform_view ( ) = default ;
(1) (since C++23)
constexpr explicit adjacent_transform_view ( V base, F fun ) ;
(2) (since C++23)

Constructs an adjacent_transform_view .

1) Default constructor. Default-initializes the underlying data members fun_ and inner_ .
2) Move constructs the underlying data members: fun_ with std :: move ( fun ) and inner_ with std :: move ( base ) .

Parameters

base - the underlying view
fun - the N-ary transformation function

Example

Run this code 
#include <algorithm>
#include <iostream>
#include <iterator>
#include <ranges>
 
int main()
{
    constexpr static auto v = {1, 2, 3, 4, 5};
    constexpr auto mul = [](auto... x) { return (... * x); };
    constexpr auto view = std::views::adjacent_transform<3>(v, mul);
    std::ranges::copy(view, std::ostream_iterator<int>(std::cout, " "));
    std::cout << '\n';
}
