not the case. The <code>tracing</code> crate’s macros ensure that all events are
|
||
registered, but if the event is constructed through other means, the

user is responsible for ensuring that <a href="../../tracing_core/subscriber/trait.Subscriber.html#method.register_callsite" title="method tracing_core::subscriber::Subscriber::register_callsite"><code>register_callsite</code></a>

||
caller wishes to apply the wrapped subscriber’s filter before choosing
|
||
whether to record the event, it may first call <a href="struct.Context.html#method.enabled" title="method tracing_subscriber::layer::Context::enabled"><code>Context::enabled</code></a> to
|
||
check whether the event would be enabled. This allows <code>Layer</code>s to

elide constructing the event if it would not be recorded.</li>
