<p>A light-weight channel using <code>Future</code>. A relay channel does not implement
|
||
<code>Send</code>, and so is not meant for synchronizing between threads. Instead,
|
||
its used to send message between tasks that live in the same thread.</p>
|
||
<p>It is similar to the <code>oneshot</code> channel in the <code>futures</code> crate, but since
|
||
it is not meant for sending across threads, it performs about twice as
|
||
fast.</p>

<h2>Search Tricks</h2>
|
||
|
||
<p>
|
||
Prefix searches with a type followed by a colon (e.g.
|
||
<code>fn:</code>) to restrict the search to a given type.
|
||
</p>
|
||
|
||
<p>
|
||
Accepted types are: <code>fn</code>, <code>mod</code>,
|
||
<code>struct</code>, <code>enum</code>,
|
||
<code>trait</code>, <code>type</code>, <code>macro</code>,
|
||
and <code>const</code>.
|
||
</p>
|
||
|
||
<p>
|
||
Search functions by type signature (e.g.
|
||
<code>vec -> usize</code> or <code>* -> vec</code>)
|
||
