<p>The send and receive operations on channels will all return a <code>Result</code>
indicating whether the operation succeeded or not. An unsuccessful operation
is normally indicative of the other half of a channel having &quot;hung up&quot; by
being dropped in its corresponding thread.</p>

<p>Once half of a channel has been deallocated, most operations can no longer
continue to make progress, so <code>Err</code> will be returned.
