|
||
<p>Conceptually, each <code>Parker</code> has an associated token which is initially not present:</p>
|
||
<ul>
|
||
<li>
|
||
<p>The <a href="struct.Parker.html#method.park" title="method crossbeam_utils::sync::Parker::park"><code>park</code></a> method blocks the current thread unless or until the token is available, at
|
||
which point it automatically consumes the token.</p>
|
||
</li>
|
||
<li>
|
||
<p>The <a href="struct.Parker.html#method.park_timeout" title="method crossbeam_utils::sync::Parker::park_timeout"><code>park_timeout</code></a> and <a href="struct.Parker.html#method.park_deadline" title="method crossbeam_utils::sync::Parker::park_deadline"><code>park_deadline</code></a> methods work the same as <a href="struct.Parker.html#method.park" title="method crossbeam_utils::sync::Parker::park"><code>park</code></a>, but block for
|
||
a specified maximum time.</p>
|
||
</li>
|
||
<li>
|
||
<p>The <a href="struct.Unparker.html#method.unpark" title="method crossbeam_utils::sync::Unparker::unpark"><code>unpark</code></a> method atomically makes the token available if it wasn’t already. Because the
|
||
token is initially absent, <a href="struct.Unparker.html#method.unpark" title="method crossbeam_utils::sync::Unparker::unpark"><code>unpark</code></a> followed by <a href="struct.Parker.html#method.park" title="method crossbeam_utils::sync::Parker::park"><code>park</code></a> will result in the second call
|
||
returning immediately.</p>
|
||
</li>
|
||
</ul>
|
||
<p>In other words, each <code>Parker</code> acts a bit like a spinlock that can be locked and unlocked using
|
||
<a href="struct.Parker.html#method.park" title="method crossbeam_utils::sync::Parker::park"><code>park</code></a> and <a href="struct.Unparker.html#method.unpark" title="method crossbeam_utils::sync::Unparker::unpark"><code>unpark</code></a>.</p>
