<p>This function only works for futures whose item and error types are <code>()</code>

difficulty for you please let us know!</p>

|

|
|
<p>This method will poll the internal future, testing if it's completed
|
|||
|
|
yet. The <code>notify</code> argument is used as a sink for notifications sent to
|
|||
|
|
this future. That is, while the future is being polled, any call to
|
|||
|
|
<code>task::current()</code> will return a handle that contains the <code>notify</code>
|
|||
|
|
specified.</p>
|
|||
|
|
<p>If this function returns <code>NotReady</code>, then the <code>notify</code> should have been
|
|||
|
|
scheduled to receive a notification when poll can be called again.
|
|||
|
|
Otherwise if <code>Ready</code> or <code>Err</code> is returned, the <code>Spawn</code> task can be
|
|||
|
|
safely destroyed.</p>
|
|||
|
|
<p>Note that <code>notify</code> itself is passed as a shared reference, and is itself
|
|||
|
|
not required to be a <code>NotifyHandle</code>. The <code>Clone</code> and <code>Into</code> trait bounds
|
|||
|
|
will be used to convert this <code>notify</code> to a <code>NotifyHandle</code> if necessary.
|
|||
|
|
This construction can avoid an unnecessary atomic reference count bump
|

|
|
in some situations.</p>

the <code>id</code> specified very carefully, explicitly calling functions like the

safe to encode a pointer itself into the <code>id</code> specified, such as an

<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>)
|
|||
|
|
