<p><code>SourceFd</code> enables registering any type with an FD with <a href="../struct.Poll.html"><code>Poll</code></a>.</p>
|

<p>While only implementations for TCP and UDP are provided, Mio supports
|

registering any FD that can be registered with the underlying OS selector.
|
||
<code>SourceFd</code> provides the necessary bridge.</p>
|
||
<p>Note that <code>SourceFd</code> takes a <code>&RawFd</code>. This is because <code>SourceFd</code> <strong>does
|
||
not</strong> take ownership of the FD. Specifically, it will not manage any
|
||
lifecycle related operations, such as closing the FD on drop. It is expected
