-// the next endpoint.

-// This class manages socket timeouts by applying the concept of a deadline.

-//
-// +----------------+ +----------------+
-// | | | |
-// | check_deadline |<---+ | check_deadline |<---+
-// | | | async_wait() | | | async_wait()
-// +----------------+ | on input +----------------+ | on output
-// | | deadline | | deadline
-// +---------+ +---------+
-//
-// If either deadline actor determines that the corresponding deadline has
-// expired, the socket is closed and any outstanding operations are cancelled.
-//
-// The input actor reads messages from the socket, where messages are delimited
-// by the newline character:
-//
-// +------------+
-// | |
-// | start_read |<---+
-// | | |
-// +------------+ |
-// | |
-// async_- | +-------------+
-// read_- | | |
-// until() +--->| handle_read |
-// | |
-// +-------------+
-//
-// The deadline for receiving a complete message is 30 seconds. If a non-empty
-// message is received, it is delivered to all subscribers. If a heartbeat (a
-// message that consists of a single newline character) is received, a heartbeat
-// is enqueued for the client, provided there are no other messages waiting to
-// be sent.
-//
-// The output actor is responsible for sending messages to the client:
-//
-// +--------------+
-// | |<---------------------+
-// | await_output | |
-// | |<---+ |
-// +--------------+ | |
-// | | | async_wait() |

-// | | async_write() | |
-// | start_write |-------------->| handle_write |
-// | | | |
-// +-------------+ +--------------+
-//
-// The output actor first waits for an output message to be enqueued. It does
-// this by using a steady_timer as an asynchronous condition variable. The
-// steady_timer will be signalled whenever the output queue is non-empty.
-//
-// Once a message is available, it is sent to the client. The deadline for
-// sending a complete message is 30 seconds. After the message is successfully
-// sent, the output actor again waits for the output queue to become non-empty.
