|

|
||
<p>The <code>make_logger</code> closure is passed a <code>MaxLogLevel</code> object, which the
|
||
logger should use to keep the global maximum log level in sync with the
|
||
highest log level that the logger will not ignore.</p>
|
||
|
||
<p>This function may only be called once in the lifetime of a program. Any log
|
||
events that occur before the call to <code>set_logger</code> completes will be
|
||
ignored.</p>
|
||
|
||
<p>This function does not typically need to be called manually. Logger
|
||
implementations should provide an initialization method that calls
|
||
<code>set_logger</code> internally.</p>
|
||
|
||
<p>Requires the <code>use_std</code> feature (enabled by default).</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>)
