std::ranges:: views:: join_with, std::ranges:: join_with_view

join_with_view models input_range .

join_with_view models forward_range when:

• ranges:: range_reference_t < V > is a reference, and
• V and ranges:: range_reference_t < V > each model forward_range .

join_with_view models bidirectional_range when:

• ranges:: range_reference_t < V > is a reference,
• V , ranges:: range_reference_t < V > , and Pattern each models bidirectional_range , and
• ranges:: range_reference_t < V > and Pattern each model common_range .

join_with_view models common_range when:

• ranges:: range_reference_t < V > is a reference, and
• V and ranges:: range_reference_t < V > each model forward_range and common_range .

Example

#include <iostream>
#include <ranges>
#include <string_view>
#include <vector>
 
int main()
{
    using namespace std::literals;
 
    std::vector v{"This"sv, "is"sv, "a"sv, "test."sv};
    auto joined = v | std::views::join_with(' ');
 
    for (auto c : joined)
        std::cout << c;
    std::cout << '\n';
}

This is a test.
