std::basic_...w::ends_with(3) C++ Standard Libarystd::basic_...w::ends_with(3) NAME std::basic_string_view::ends_with - std::basic_string_view::ends_with Synopsis constexpr bool ends_with( basic_string_view sv ) const noexcept; (1) (since C++20) constexpr bool ends_with( CharT ch ) const noexcept; (2) (since C++20) constexpr bool ends_with( const CharT* s ) const; (3) (since C++20) Checks if the string view ends with the given suffix, where 1) the suffix is a string view. Effectively returns size() >= sv.size() && compare(size() - sv.size(), npos, sv) == 0. 2) the suffix is a single character. Effectively returns !empty() && Traits::eq(back(), ch). 3) the suffix is a null-terminated character string. Effectively re- turns ends_with(basic_string_view(s)). Parameters sv - a string view which may be a result of implicit conversion from std::basic_string ch - a single character s - a null-terminated character string Return value true if the string view ends with the provided suffix, false other- wise.
