This member contains the name and the role name of the discovered subscription.

◆ trust_protection_info

struct DDS_EndpointTrustProtectionInfo DDS_SubscriptionBuiltinTopicData::trust_protection_info

<<extension>> Trust plugins protection information associated with the discovered DataReader.

Trust Plugins is a generic abstraction that represents any plugin intended to do transformation, interception, and validation of exchanged data and metadata.

trust_protection_info contains information about how RTPS wire serialization, discovery, and liveliness interact with the loaded Trust Plugins. Two endpoints will not match if their trust_protection_info is incompatible.

The meaning of the contents of this field may vary depending on what Trust Plugins the endpoint is using. For information about how this field interacts with the RTI Security Plugins, please refer to the RTI Security Plugins User's Manual.

Trust Plugins is a generic abstraction that represents any plugin intended to do transformation, interception, and validation of exchanged data and metadata.

trust_algorithm_info contains information about what algorithms the loaded Trust Plugins are running. Two endpoints will not match if their trust_algorithm_info are incompatible.

The meaning of the contents of this field may vary depending on what Trust Plugins the endpoint is using. For information about how this field interacts with the RTI Security Plugins, please refer to the RTI Security Plugins User's Manual.
