concat_view() = default;	(1)	(since C++26)
constexpr concat_view( Views... views );	(2)	(since C++26)

Overload	`views_`
(1)	default-initialized
(2)	initialized with std::move(views)...

Parameters

views

-

view objects to adapt

Notes

In order to call the default constructor, Views must be explicitly provided and all types it contains must be default-initializable.

Example

An early preview of the example is available in Compiler Explorer.

Run this code

#include <algorithm>
#include <ranges>
 
int main()
{
    using namespace std::ranges;
 
    static constexpr concat_view<empty_view<char>> concat1{}; // overload (1)
    static_assert(equal(concat1, views::empty<char>));
 
    static constexpr auto con = {'c', 'o', 'n'};
    static constexpr char cat[]{'c', 'a', 't', '\0'};
    static constexpr auto concat2{views::concat(con, cat)};   // overload (2)
    static_assert(equal(concat2, "concat"));
}
