Struct rmw_topic_endpoint_info_t 

#[repr(C)]
pub struct rmw_topic_endpoint_info_t {
    pub node_name: *const c_char,
    pub node_namespace: *const c_char,
    pub topic_type: *const c_char,
    pub endpoint_type: Type,
    pub endpoint_gid: rmw_gid_t,
    pub qos_profile: rmw_qos_profile_t,
}

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.

Fields

node_name: *const c_char

Node that owns the endpoint.

node_namespace: *const c_char

That node’s namespace.

topic_type: *const c_char

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

endpoint_type: Type

Publisher or subscription.

endpoint_gid: rmw_gid_t

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

qos_profile: rmw_qos_profile_t

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.
