Module request_counts 

Structs

RequestRateWindows

Per-PayloadRequestKind decaying call-rate estimates over three trailing windows. Each [DecayingCounter] settles at rate · τ, so the values read directly as “estimated calls in the last hour / day / month”. Pairs with the lock-free all-time request_counters totals, which stay exact.

Functions

request_counts_subtree

Build the requests subtree: one object per [PayloadRequestKind] variant, keyed by its Display name, holding the all-time total plus the decaying per_hour / per_day / per_month rate estimates evaluated at now.
