Struct DeliveryMeter 

Source 
pub struct DeliveryMeter(Arc<DeliveryAtomics>);
Expand description

Shared, lock-free honest-clock meter. Producers bump it in place with a single atomic add — the reliable ack machinery on ack / retransmission-exhaustion (impl A), or an application-return-byte reader (impl B). The window driver reads byte deltas via DeliveryClock. No channel, no per-frame allocation, no dedup bookkeeping (a duplicate ack merely over-credits by one frame, which the SURB ceiling and cwnd still bound). Modelled on the existing atomic BalancerStateValues.
