Struct QosRingShapePolicy 

pub struct QosRingShapePolicy {
    pub qos: Arc<QosPolicy>,
    pub hysteresis: Duration,
}

QoS-aware shape policy: consumes the Ordering declaration on a QosPolicy alongside the peer counts.

Decision matrix (after the hysteresis cooldown):

declaration	ring	decision
GlobalFifo	unstamped	morph to Vyukov (the proven global-FIFO structure)
GlobalFifo	stamped	counts-based composed shape; the ordering axis is served by the merge flag, which the OrderingPolicy flips
PerProducer	either	counts-based default (which also walks an earlier Vyukov morph back once the declaration is withdrawn)

Fields

qos: Arc<QosPolicy>

hysteresis: Duration
