Client sample out of main scope

[codesian]

Hi, a begginer here.

There is an example about client use out of main scope? How to store on a class member, something more generic than shot and close on main?

Thanks!

See bench.cpp

mqtt_cpp/example/bench.cpp

Lines 1054 to 1070 in 2776579

	using client_t = decltype(
	MQTT_NS::make_async_client(
	std::declval<as::io_context&>(),
	host,
	port,
	version
	)
	);
	struct client_info : client_info_base {
	client_info(client_t c, std::size_t index, std::size_t payload_size, std::size_t times, std::size_t idle_count)
	:client_info_base(index, payload_size, times, idle_count),
	c{MQTT_NS::force_move(c)}
	{
	}
	client_t c;
	};

It is a little tricky because mqtt_cpp supports various underlying layer without virtual function mechanism to support templates.
So we need to use decltype() to get the type information.
