|

|
|
<p>Currently, there are two different errors that can occur:</p>
|
|||
|
|
<ul>
|
|||
|
|
<li>
|
|||
|
|
<p><code>shutdown</code> occurs when a timer operation is attempted, but the timer
|
|||
|
|
instance has been dropped. In this case, the operation will never be able
|
|||
|
|
to complete and the <code>shutdown</code> error is returned. This is a permanent
|
|||
|
|
error, i.e., once this error is observed, timer operations will never
|
|||
|
|
succeed in the future.</p>
|
|||
|
|
</li>
|
|||
|
|
<li>
|
|||
|
|
<p><code>at_capacity</code> occurs when a timer operation is attempted, but the timer
|
|||
|
|
instance is currently handling its maximum number of outstanding delays.
|
|||
|
|
In this case, the operation is not able to be performed at the current
|
|||
|
|
moment, and <code>at_capacity</code> is returned. This is a transient error, i.e., at
|
|||
|
|
some point in the future, if the operation is attempted again, it might
|
|||
|
|
succeed. Callers that observe this error should attempt to <a href="https://en.wikipedia.org/wiki/Load_Shedding">shed load</a>. One
|
|||
|
|
way to do this would be dropping the future that issued the timer operation.</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>)
|
|||
|
|
