Event-Based Communication

Running The Example

This example demonstrates iceoryx2's event multiplexing mechanism in a more complex setup. The iceoryx2 Publisher and Subscriber are integrated into custom ExamplePublisher and ExampleSubscriber classes, which also incorporate an additional iceoryx2 Notifier and Listener. This setup enables automatic event emission whenever an ExamplePublisher or ExampleSubscriber is created or dropped. Additionally, events are emitted whenever a new Sample is sent or received.

When a struct implements SynchronousMultiplexing, it can be attached to a WaitSet. Both ExamplePublisher and ExampleSubscriber implement this interface by forwarding calls to their underlying Listener, which already provides an implementation of SynchronousMultiplexing.

The WaitSet notifies the user of the origin of an event notification. The user can then acquire the EventId from the Listener. Based on the value of the EventId, the user can identify the specific event that occurred and take appropriate action.

Terminal 1

cargo run --example event_based_comm_publisher

Terminal 2

cargo run --example event_based_comm_subscriber

Feel free to run multiple publishers or subscribers in parallel.
