Description
Expose buffer backend support metadata through
rmw_zenoh_cpptopic endpoint graph info.rmw_zenoh_cppalready advertises and parses buffer backend metadata through liveliness tokens. This change carries that parsed metadata intormw_topic_endpoint_info_twhen handling publisher/subscription endpoint graph queries, allowing higher-level graph APIs andros2 topic info -vto report backend support for Zenoh endpoints.Is this user-facing behavior change?
Yes. Users can inspect Zenoh publisher/subscription endpoint backend support through graph introspection, including
ros2 topic info <topic> -v, once the correspondingrmw,rclpy, and CLI endpoint-info support is present.Did you use Generative AI?
Yes. GPT-5.5 in Cursor was used to help draft changes in this pull request.
