|
|||
|
|
<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 <code>Sender::send</code> method will only
|
|||
|
|
allow sending one message and the next message can only be sent once the
|
|||
|
|
first was consumed.</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>)
|
|||
|
|
