|
||
<p><code>take()</code> allows for taking <code>T</code> out of a <code>&mut T</code>, doing anything with it including consuming it, and producing another <code>T</code> to put back in the <code>&mut T</code>.</p>
|
||
<p>During <code>take()</code>, if a panic occurs, the entire process will be aborted, as there's no valid <code>T</code> to put back into the <code>&mut T</code>.
|
||
Use <code>take_or_recover()</code> to replace the <code>&mut T</code> with a recovery value before continuing the panic.</p>
|
||
<p>Contrast with <code>std::mem::replace()</code>, which allows for putting a different <code>T</code> into a <code>&mut T</code>, but requiring the new <code>T</code> to be available before being able to consume the old <code>T</code>.</p>
