+/**
+ * The basic_channel class template is used for sending messages between
+ * different parts of the same application. A <em>message</em> is defined as a
+ * collection of arguments to be passed to a completion handler, and the set of
+ * messages supported by a channel is specified by its @c Traits and
+ * <tt>Signatures...</tt> template parameters. Messages may be sent and received
+ * using asynchronous or non-blocking synchronous operations.
+ *
+ * Unless customising the traits, applications will typically use the @c
+ * experimental::channel alias template. For example:
+ * @code void send_loop(int i, steady_timer& timer,
+ *     channel<void(error_code, int)>& ch)
+ * {
+ *   if (i < 10)
+ *   {
+ *     timer.expires_after(chrono::seconds(1));
+ *     timer.async_wait(
+ *         [i, &timer, &ch](error_code error)
+ *         {
+ *           if (!error)
+ *           {
+ *             ch.async_send(error_code(), i,
+ *                 [i, &timer, &ch](error_code error)
+ *                 {
+ *                   if (!error)
+ *                   {
+ *                     send_loop(i + 1, timer, ch);
+ *                   }
+ *                 });
+ *           }
+ *         });
+ *   }
+ *   else
+ *   {
+ *     ch.close();
+ *   }
+ * }
+ *
+ * void receive_loop(channel<void(error_code, int)>& ch)
+ * {
+ *   ch.async_receive(
+ *       [&ch](error_code error, int i)
+ *       {
+ *         if (!error)

+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Unsafe.

+ * The basic_channel class template is not thread-safe, and would typically be

+ * thread or in the same strand. Consider using @ref basic_concurrent_channel,

+/// A channel for messages.
+/**
+ * The basic_concurrent_channel class template is used for sending messages
+ * between different parts of the same application. A <em>message</em> is
+ * defined as a collection of arguments to be passed to a completion handler,
+ * and the set of messages supported by a channel is specified by its @c Traits
+ * and <tt>Signatures...</tt> template parameters. Messages may be sent and
+ * received using asynchronous or non-blocking synchronous operations.
+ *
+ * Unless customising the traits, applications will typically use the @c
+ * experimental::concurrent_channel alias template. For example:
+ * @code void send_loop(int i, steady_timer& timer,
+ *     concurrent_channel<void(error_code, int)>& ch)
+ * {
+ *   if (i < 10)
+ *   {
+ *     timer.expires_after(chrono::seconds(1));
+ *     timer.async_wait(
+ *         [i, &timer, &ch](error_code error)
+ *         {
+ *           if (!error)
+ *           {
+ *             ch.async_send(error_code(), i,
+ *                 [i, &timer, &ch](error_code error)
+ *                 {
+ *                   if (!error)
+ *                   {
+ *                     send_loop(i + 1, timer, ch);
+ *                   }
+ *                 });
+ *           }
+ *         });
+ *   }
+ *   else
+ *   {
+ *     ch.close();
+ *   }
+ * }
+ *
+ * void receive_loop(concurent_channel<void(error_code, int)>& ch)
+ * {
+ *   ch.async_receive(
+ *       [&ch](error_code error, int i)
+ *       {
+ *         if (!error)
+ *         {
+ *           std::cout << "Received " << i << "\n";
+ *           receive_loop(ch);
+ *         }
+ *       });
+ * } @endcode
+ *
+ * @par Thread Safety
+ * @e Distinct @e objects: Safe.@n
+ * @e Shared @e objects: Safe.
+ *
+ * The basic_concurrent_channel class template is thread-safe, and would
+ * typically be used for passing messages between application code that run on
+ * different threads. Consider using @ref basic_channel, and its alias template
+ * @c experimental::channel, to pass messages between code running in a single
+ * thread or on the same strand.

+/// Creates an initiation function object that may be used to launch a

+/**
+ * The experimental::co_composed utility simplifies the implementation of
+ * composed asynchronous operations by automatically adapting a coroutine to be
+ * an initiation function object for use with @c async_initiate. When awaiting
+ * asynchronous operations, the coroutine automatically uses a conforming
+ * intermediate completion handler.
+ *
+ * @param implementation A function object that contains the coroutine-based
+ * implementation of the composed asynchronous operation. The first argument to
+ * the function object represents the state of the operation, and may be used
+ * to test for cancellation. The remaining arguments are those passed to @c
+ * async_initiate after the completion token.
+ *
+ * @param io_objects_or_executors Zero or more I/O objects or I/O executors for
+ * which outstanding work must be maintained while the operation is incomplete.
+ *
+ * @par Per-Operation Cancellation
+ * By default, per-operation cancellation is disabled for composed operations
+ * that use experimental::co_composed. It must be explicitly enabled by calling
+ * the state's @c reset_cancellation_state function.
+ *
+ * @par Examples
+ * The following example illustrates manual error handling and explicit checks
+ * for cancellation. The completion handler is invoked via a @c co_yield to the
+ * state's @c complete function, which never returns.
+ *
+ * @code template <typename CompletionToken>
+ * auto async_echo(tcp::socket& socket,
+ *     CompletionToken&& token)
+ * {
+ *   return asio::async_initiate<
+ *     CompletionToken, void(std::error_code)>(
+ *       asio::experimental::co_composed(
+ *         [](auto state, tcp::socket& socket) -> void
+ *         {
+ *           state.reset_cancellation_state(
+ *             asio::enable_terminal_cancellation());
+ *
+ *           while (!state.cancelled())
+ *           {
+ *             char data[1024];
+ *             auto [e1, n1] =
+ *               co_await socket.async_read_some(
+ *                 asio::buffer(data),
+ *                 asio::as_tuple(asio::deferred));
+ *
+ *             if (e1)
+ *               co_yield state.complete(e1);
+ *
+ *             if (!!state.cancelled())
+ *               co_yield state.complete(
+ *                 make_error_code(asio::error::operation_aborted));
+ *
+ *             auto [e2, n2] =
+ *               co_await asio::async_write(socket,
+ *                 asio::buffer(data, n1),
+ *                 asio::as_tuple(asio::deferred));
+ *

+ *               co_yield state.complete(e2);
+ *           }
+ *         }, socket),
+ *       token, std::ref(socket));
+ * } @endcode
+ *
+ * This next example shows exception-based error handling and implicit checks
+ * for cancellation. The completion handler is invoked after returning from the
+ * coroutine via @c co_return. Valid @c co_return values are specified using
+ * completion signatures passed to the @c co_composed function.

+ * The @c use_coro_t class, with its value @c use_coro, is used to represent an
+ * operation that can be awaited by the current resumable coroutine. This
+ * completion token may be passed as a handler to an asynchronous operation.
+ * For example:

+ *   std::size_t n = co_await my_socket.async_read_some(buffer, use_coro);

+ * } @endcode
+ *
+ * When used with co_await, the initiating function (@c async_read_some in the
+ * above example) suspends the current coroutine. The coroutine is resumed when
+ * the asynchronous operation completes, and the result of the operation is
+ * returned.
+ *
+ * Note that this token is not the most efficient (use @c asio::deferred
+ * for that) but does provide type erasure, as it will always return a @c coro.
