+/// Defines the runner-event which is sent from the test runners to the report aggregator.
+///
+/// This macro defines a number of things related to the reporting infrastructure and the interface
+/// used. First of all, it defines the enum of all of the possible events that the runners can send
+/// to the aggregator. For each one of the variants it defines a separate struct for it to allow the
+/// variant field in the enum to be put in a [`Box`].
+///
+/// In addition to the above, it defines [`From`] implementations for the various event types for
+/// the [`RunnerEvent`] enum essentially allowing for events such as [`CorpusFileDiscoveryEvent`] to
+/// be converted into a [`RunnerEvent`].
+///
+/// In addition to the above, it also defines the [`RunnerEventReporter`] which is a wrapper around
+/// an [`UnboundedSender`] allowing for events to be sent to the report aggregator.
+///
+/// With the above description, we can see that this macro defines almost all of the interface of
+/// the reporting infrastructure, from the enum itself, to its associated types, and also to the
+/// reporter that's used to report events to the aggregator.
