Add an overload like this:

#if !defined(BOOST_NO_CXX17_HDR_STRING_VIEW)

inline std::string_view api_function( std::string_view str ) { boost::string_view res = api_function( boost::string_view(str.data(), str.size())); return std::string_view(res.data(), res.size()); }

#endif

As I said, all code that used to call the function with a std::string or with a string literal is now broken under C++17.

Ok, let it be template< typename T > inline typename enable_if< is_same< T, std::string_view >, std::string_view

::type api_function( T str ) { ... }
