[edit] Example
An early preview of the example is available in Compiler Explorer.
#include #include int main() { using namespace std::ranges; static constexpr concat_view<empty_view> concat1{}; // overload (1) static_assert(equal(concat1, views::empty)); 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")); }
