use <ahref="type.RawRestoreState.html"title="type critical_section::RawRestoreState"><code>RawRestoreState</code></a> so that they can use the inner value.</p>
<p>This can be useful to avoid <code>Option</code> when storing a <code>RestoreState</code> in a
struct field, or a <code>static</code>.</p>
<p>Note that due to the safety contract of <ahref="fn.acquire.html"title="fn critical_section::acquire"><code>acquire</code></a>/<ahref="fn.release.html"title="fn critical_section::release"><code>release</code></a>, you must not pass
a <code>RestoreState</code> obtained from this method to <ahref="fn.release.html"title="fn critical_section::release"><code>release</code></a>.</p>
