<p>A file descriptor or socket is considered readable or writable when a read or write
operation on it would not block. This doesnt mean the read or write operation will
succeed, it only means the operation will return immediately.</p>
<p>If interest is set in both readability and writability, the two kinds of events might be
delivered either separately or together.</p>
<p>For example, interest in <code>Event { key: 7, readable: true, writable: true }</code> might result in
a single <a href="struct.Event.html" title="struct polling::Event"><code>Event</code></a> of the same form, or in two separate <a href="struct.Event.html" title="struct polling::Event"><code>Event</code></a>s:</p>
<ul>
<li><code>Event { key: 7, readable: true, writable: false }</code></li>
<li><code>Event { key: 7, readable: false, writable: true }</code></li>
</ul>
<p>Note that interest in I/O events needs to be re-enabled using
<a href="struct.Poller.html#method.modify" title="method polling::Poller::modify"><code>modify()</code></a> again after an event is delivered if were interested in
the next event of the same kind.</p>
<p>It is possible to register interest in the same file descriptor or socket using multiple
separate <a href="struct.Poller.html" title="struct polling::Poller"><code>Poller</code></a> instances. When the event is delivered, one or more <a href="struct.Poller.html" title="struct polling::Poller"><code>Poller</code></a>s are
notified with that event. The exact number of <a href="struct.Poller.html" title="struct polling::Poller"><code>Poller</code></a>s notified depends on the
underlying platform. When registering multiple sources into one event, the user should
be careful to accommodate for events lost to other pollers.</p>
<p>One may also register one source into other, non-<code>polling</code> event loops, like GLibs
context. While the plumbing will vary from platform to platform, in general the <a href="struct.Poller.html" title="struct polling::Poller"><code>Poller</code></a>
will act as if the source was registered with another <a href="struct.Poller.html" title="struct polling::Poller"><code>Poller</code></a>, with the same caveats
as above.</p>
