std::basic_...append_range(3) C++ Standard Libarystd::basic_...append_range(3) NAME std::basic_string::append_range - std::basic_string::append_range Synopsis template< container-compatible-range<CharT> R > (since C++23) constexpr std::basic_string& append_range( R&& rg ); Appends all characters from the range rg. Equivalent to return append(std::basic_string( std::from_range, std::forward<R>(rg), get_allocator())); Parameters rg - a container compatible range Return value *this Complexity Linear in size of rg. Exceptions If the operation would result in size() > max_size(), throws std::length_error. If an exception is thrown for any reason, this function has no ef- fect (strong exception safety guarantee). Notes Feature-test macro Value Std Feature __cpp_lib_containers_ranges 202202L (C++23) member functions that accept container compatible range Example // Run this code #include <cassert> #include <string> int main() { std::string head{"long long"}; const auto tail = {' ', 'i', 'n', 't'}; #ifdef __cpp_lib_containers_ranges head.append_range(tail); #else head.append(tail.begin(), tail.end()); #endif assert(head == "long long int"); } See also append appends characters to the end (public member function) http://cppreference.com 2024.06.10 std::basic_...append_range(3)
