<p>This function is intended for runtime reconfiguration of filters on traces
when the filter recalculation is much less frequent than trace events are.
The alternative is to have the <a href="../trait.Subscriber.html" title="trait tracing_core::Subscriber"><code>Subscriber</code></a> that supports runtime
reconfiguration of filters always return <a href="../subscriber/struct.Interest.html#method.sometimes" title="associated function tracing_core::subscriber::Interest::sometimes"><code>Interest::sometimes()</code></a> so that
<a href="../trait.Subscriber.html#tymethod.enabled" title="trait tracing_core::Subscriber"><code>enabled</code></a> is evaluated for every event.</p>
<p>This function will also re-compute the global maximum level as determined by
the <a href="../trait.Subscriber.html#method.max_level_hint" title="method tracing_core::Subscriber::max_level_hint"><code>max_level_hint</code></a> method. If a <a href="../trait.Subscriber.html" title="trait tracing_core::Subscriber"><code>Subscriber</code></a>
implementation changes the value returned by its <code>max_level_hint</code>
implementation at runtime, then it <strong>must</strong> call this function after that
value changes, in order for the change to be reflected.</p>
<p>See the <a href="index.html#rebuilding-cached-interest" title="mod tracing_core::callsite">documentation on callsite interest caching</a> for
additional information on this functions usage.</p>
