<p>Objects of this type receive <a href="struct.ConnectionEvent.html" title="struct noq_proto::ConnectionEvent"><code>ConnectionEvent</code></a>s and emit <a href="struct.EndpointEvent.html" title="struct noq_proto::EndpointEvent"><code>EndpointEvent</code></a>s and application
<a href="enum.Event.html" title="enum noq_proto::Event"><code>Event</code></a>s to make progress. To handle timeouts, a <code>Connection</code> returns timer updates and
expects timeouts through various methods. A number of simple getter methods are exposed
to allow callers to inspect some of the connection state.</p>
<p><code>Connection</code> has roughly 4 types of methods:</p>
<ul>
<li>A. Simple getters, taking <code>&amp;self</code></li>
<li>B. Handlers for incoming events from the network or system, named <code>handle_*</code>.</li>
<li>C. State machine mutators, for incoming commands from the application. For convenience we
refer to this as “performing I/O” below, however as per the design of this library none of the
functions actually perform system-level I/O. For example, <a href="struct.RecvStream.html#method.read" title="method noq_proto::RecvStream::read"><code>read</code></a> and
<a href="struct.SendStream.html#method.write" title="method noq_proto::SendStream::write"><code>write</code></a>, but also things like <a href="struct.SendStream.html#method.reset" title="method noq_proto::SendStream::reset"><code>reset</code></a>.</li>
<li>D. Polling functions for outgoing events or actions for the caller to
take, named <code>poll_*</code>.</li>
</ul>
<p>The simplest way to use this API correctly is to call (B) and (C) whenever
appropriate, then after each of those calls, as soon as feasible call all
polling methods (D) and deal with their outputs appropriately, e.g. by
passing it to the application or by making a system-level I/O call. You
should call the polling functions in this order:</p>
<ol>
<li><a href="struct.Connection.html#method.poll_transmit" title="method noq_proto::Connection::poll_transmit"><code>poll_transmit</code></a></li>
<li><a href="struct.Connection.html#method.poll_timeout" title="method noq_proto::Connection::poll_timeout"><code>poll_timeout</code></a></li>
<li><a href="struct.Connection.html#method.poll_endpoint_events" title="method noq_proto::Connection::poll_endpoint_events"><code>poll_endpoint_events</code></a></li>
<li><a href="struct.Connection.html#method.poll" title="method noq_proto::Connection::poll"><code>poll</code></a></li>
</ol>
<p>Currently the only actual dependency is from (2) to (1), however additional
dependencies may be added in future, so the above order is recommended.</p>
<p>(A) may be called whenever desired.</p>
<p>Care should be made to ensure that the input events represent monotonically
increasing time. Specifically, calling <a href="struct.Connection.html#method.handle_timeout" title="method noq_proto::Connection::handle_timeout"><code>handle_timeout</code></a>
with events of the same <a href="https://doc.rust-lang.org/nightly/std/time/struct.Instant.html" title="struct std::time::Instant"><code>Instant</code></a> may be interleaved in any order with a
call to <a href="struct.Connection.html#method.handle_event" title="method noq_proto::Connection::handle_event"><code>handle_event</code></a> at that same instant; however
events or timeouts with different instants must not be interleaved.</p>
