Crate zerodds_xrce_agent 

XRCE Agent — DDS participant wrapper with a pull model (spec §7.3).

Crate zerodds-xrce-agent.

Spec mapping

OMG DDS-XRCE 1.0 §7.3: “the XRCE Agent represents the XRCE client in the DDS data space; client-pull model for disconnected devices.”

We provide an in-process agent state machine XrceAgent with:

• register_client(client_key) — a client is registered by ClientKey; the agent creates one object slot per client.
• create_object(...) — spec §7.8.3 CREATE path.
• delete_object(...) — spec §7.8.3 DELETE path.
• submit_sample(reader, payload) — DDS-side push: places a sample into the pull queue of a DataReader.
• pull_sample(client_key, reader) — spec §7.3 client-pull model.

The agent itself encapsulates no DDS stack — that is the job of the integrating application. We only provide the object management + pull queue.

Safety classification: STANDARD.
