        A composed connect handler must meet the requirements for a handler.
        A value h of a composed connect
        handler class should work correctly in the expression h(ec,
        i),
        where ec is an lvalue of
        type const error_code
        and i is an lvalue of the
        type Iterator used in the
        corresponding connect()
        or async_connect()` function.
      
A free function as a composed connect handler:
void connect_handler( const boost::system::error_code& ec, boost::asio::ip::tcp::resolver::iterator iterator) { ... }
A composed connect handler function object:
struct connect_handler { ... template <typename Iterator> void operator()( const boost::system::error_code& ec, Iterator iterator) { ... } ... };
        A non-static class member function adapted to a composed connect handler
        using bind():
      
void my_class::connect_handler( const boost::system::error_code& ec, boost::asio::ip::tcp::resolver::iterator iterator) { ... } ... boost::asio::async_connect(..., boost::bind(&my_class::connect_handler, this, boost::asio::placeholders::error, boost::asio::placeholders::iterator));
