std::basic_...assign_range(3) C++ Standard Libarystd::basic_...assign_range(3) NAME std::basic_string::assign_range - std::basic_string::assign_range Synopsis template< container-compatible-range<CharT> R > (since C++23) constexpr std::basic_string& assign_range( R&& rg ); Replaces the contents of the string with the values in the range rg. Equivalent to return assign( 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() { const auto source = {'s', 'o', 'u', 'r', 'c', 'e'}; std::string destination{"destination"}; #ifdef __cpp_lib_containers_ranges destination.assign_range(source); #else destination.assign(source.begin(), source.end()); #endif assert(destination == "source"); } See also assign assign characters to a string (public member function) operator= assigns values to the string (public member function) constructor constructs a basic_string (public member function) http://cppreference.com 2024.06.10 std::basic_...assign_range(3)
