Module qos 

Datenmodell fuer die DDS-XML 1.0 §7.3.2 QoS-Profile-Library.

Spec-Quelle: OMG DDS-XML 1.0 §7.3.2 (QoS Library Building Block) + DDS 1.4 §2.2.3 (22 Standard-QoS-Policies).

Schicht-Disziplin

Die einzelnen Policy-Strukturen (DurabilityQosPolicy, …) und die Aggregat-Container (WriterQos, ReaderQos) leben im Crate zerodds_qos (Wire-Format-Quelle). zerodds-xml re-nutzt sie hier direkt — keine Duplikate.

Die XML-spezifischen Container EntityQos (sechs Auspraegungen fuer DataWriter/DataReader/Topic/Publisher/Subscriber/ DomainParticipant) tragen pro Policy ein Option<…>. None = “Spec-Default” (uebernommen aus zerodds-qos::*::Default); Some(p) = im XML explizit gesetzt. Die Override-Semantik der Inheritance (siehe crate::qos_inheritance) operiert auf diesen Optionen: ein Kind-Profile mit Some(p) ueberschreibt das geerbte Some/None, ein Kind-Profile mit None erbt unveraendert.
