Detailed Description

One discovered endpoint — upstream rmw_topic_endpoint_info_t.

Every string is BORROWED for the duration of the visit that hands this out; a caller that needs one past the callback copies it. That is what lets the graph slots stream without an allocator.

Field Documentation

endpoint_gid

rmw_gid_t rmw_topic_endpoint_info_t::endpoint_gid

The endpoint's identity; data all-zero when the backend has none.

endpoint_type

rmw_endpoint_type_t rmw_topic_endpoint_info_t::endpoint_type

Publisher or subscription.

node_name

const char* rmw_topic_endpoint_info_t::node_name

Node that owns the endpoint.

node_namespace

const char* rmw_topic_endpoint_info_t::node_namespace

That node's namespace.

qos_profile

rmw_qos_profile_t rmw_topic_endpoint_info_t::qos_profile

The GRANTED profile, not the requested one — which is the whole reason a consumer asks. A backend that cannot read back a remote's granted QoS reports what it MATCHED on, and must not substitute the local entity's requested profile.

topic_type

const char* rmw_topic_endpoint_info_t::topic_type

Fully-qualified type on the wire, e.g. "std_msgs/msg/Int32".
