<p>This is a simple convenience wrapper over <code>set_logger</code>, which takes a

|
|
<code>Box<Log></code> rather than a <code>&'static Log</code>. See the documentation for
|

<a href="fn.set_logger.html"><code>set_logger</code></a> for more details.</p>

<p>Requires the <code>std</code> feature.</p>
