|
||
bounded capacity.</p>
|
||
<p>This method creates a concrete implementation of the <code>Stream</code> trait which
|
||
can be used to send values across threads in a streaming fashion. This
|
||
channel is unique in that it implements back pressure to ensure that the
|
||
sender never outpaces the receiver. The channel capacity is equal to
|
||
<code>buffer + num-senders</code>. In other words, each sender gets a guaranteed slot
|
||
in the channel capacity, and on top of that there are <code>buffer</code> "first come,
|
||
first serve" slots available to all senders.</p>
|
||
<p>The <code>Receiver</code> returned implements the <code>Stream</code> trait and has access to any
|
||
number of the associated combinators for transforming the result.</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>)
