The interface CollectedDataEmitter can be typehinted in 2nd parameter of Rule::processNode():
public function processNode(Node $node, Scope&CollectedDataEmitter $scope): array
It allows rules to emit collected data directly, without having to write a separate complex Collector class. The emitted data is aggregated the same way as data from Collectors and can be consumed by rules registered for CollectedDataNode.
The actual MyCollector class in the example has to exist, to verify the data type statically, and to identify the collected data.
The referenced MyCollector class should NOT be registered as a collector, unless you also want it to collect data on its own.
$scope->emitCollectedData(MyCollector::class, ['some', 'data']);
