Struct DefaultOrderingPolicy 

pub struct DefaultOrderingPolicy {
    pub hysteresis: Duration,
    pub auto_order_threshold: Option<f64>,
}

Default ordering policy.

• Acts on the QoS declaration always: GlobalFifo arms MergeByStamp; withdrawing to PerProducer disarms back to Unordered (only when auto_order_threshold is unset - see below).
• Acts on the inversion rate only when the caller pre-authorized an automatic response by setting auto_order_threshold (inversions/sec): under a PerProducer declaration, a rate above the threshold arms MergeByStamp. The auto arm is one-way - merged pops read zero inversions by construction, so there is no symmetric signal to disarm on; disarming is the caller’s call (QoS declaration or an explicit set_ordering_mode).

Fields

hysteresis: Duration

auto_order_threshold: Option<f64>
