Add experimental::co_composed.
...
The following example illustrates a simple asynchronous operation that
implements an echo protocol in terms of a coroutine:
template <typename CompletionToken>
auto async_echo(tcp::socket& socket,
CompletionToken&& token)
{
return boost::asio::async_initiate<
CompletionToken, void(boost::system::error_code)>(
boost::asio::experimental::co_composed<
void(boost::system::error_code)>(
[](auto state, tcp::socket& socket) -> void
{
try
{
state.throw_if_cancelled(true);
state.reset_cancellation_state(
boost::asio::enable_terminal_cancellation());
for (;;)
{
char data[1024];
std::size_t n = co_await socket.async_read_some(
boost::asio::buffer(data), boost::asio::deferred);
co_await boost::asio::async_write(socket,
boost::asio::buffer(data, n), boost::asio::deferred);
}
}
catch (const boost::system::system_error& e)
{
co_return {e.code()};
}
}, socket),
token, std::ref(socket));
}

Add any_completion_handler<>.
...
The any_completion_handler<> template can be used to type-erase
completion handlers. A typical use case is to enable separate
compilation of asynchronous operation implementations. For example:
// Header file:
void async_sleep_impl(
boost::asio::any_completion_handler<void(boost::system::error_code)> handler,
boost::asio::any_io_executor ex, std::chrono::nanoseconds duration);
template <typename CompletionToken>
inline auto async_sleep(boost::asio::any_io_executor ex,
std::chrono::nanoseconds duration, CompletionToken&& token)
{
return boost::asio::async_initiate<CompletionToken, void(boost::system::error_code)>(
async_sleep_impl, token, std::move(ex), duration);
}
// Separately compiled source file:
void async_sleep_impl(
boost::asio::any_completion_handler<void(boost::system::error_code)> handler,
boost::asio::any_io_executor ex, std::chrono::nanoseconds duration)
{
auto timer = std::make_shared<boost::asio::steady_timer>(ex, duration);
timer->async_wait(boost::asio::consign(std::move(handler), timer));
}

Add consign completion token adapter.
...
The consign completion token adapter can be used to attach additional
values to a completion handler. This is typically used to keep at least
one copy of an object, such as a smart pointer, alive until the
completion handler is called.
For example:
auto timer1 = std::make_shared<boost::asio::steady_timer>(my_io_context);
timer1->expires_after(std::chrono::seconds(1));
timer1->async_wait(
boost::asio::consign(
[](boost::system::error_code ec)
{
// ...
},
timer1
)
);
auto timer2 = std::make_shared<boost::asio::steady_timer>(my_io_context);
timer2->expires_after(std::chrono::seconds(30));
std::future<void> f =
timer2->async_wait(
boost::asio::consign(
boost::asio::use_future,
timer2
)
);
