Struct LaneActivityClock 

pub struct LaneActivityClock { /* private fields */ }

Read handle over the client handler’s live lane registry, exposing each lane’s whole-seconds age since its last accepted voucher for the admin lanes surface (issue #1733). Cloning shares the same registry Arc, so the admin surface and the handler observe one set of lanes. The timestamp lives on the lane’s own delivery state, stamped under the per-lane lock the voucher-accept path already holds, so reading liveness needs no separate global lock.

Implementations

impl LaneActivityClock

pub fn empty() -> Self

An activity clock over an empty registry — reports “never” for every lane. Used where no client handler is wired (a node with no payment surface, and admin unit tests).

pub async fn ages(&self) -> HashMap<LaneKey, u64>

Whole seconds since each live lane last accepted a voucher, keyed by LaneKey. A lane whose stamp is 0 (none accepted since this process hydrated it) is omitted, so a caller reads it back as “never” rather than a bogus zero age. Best-effort: Instant-free wall-clock arithmetic, so a clock that stepped backwards can only under-report the age — the safe direction for a diagnostic.
