| <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"><code>Subscriber</code></a> that supports runtime |
| reconfiguration of filters always return <a href="../subscriber/struct.Interest.html#method.sometimes"><code>Interest::sometimes()</code></a> so that |
| <a href="../trait.Subscriber.html#tymethod.enabled"><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"><code>max_level_hint</code></a> method. If a <a href="../trait.Subscriber.html"><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">documentation on callsite interest caching</a> for |
| additional information on this function’s usage.</p> |
