Struct VirtualClock 

pub struct VirtualClock { /* private fields */ }

A virtual clock for simulation: time is a counter the scheduler advances, plus a fixed wall-clock base so epoch_now stays meaningful for expiry math.

Implementations

impl VirtualClock

pub fn new(epoch_base: Epoch) -> Arc<Self>

A virtual clock starting at epoch_base (the simulated wall time at virtual zero).

pub fn advance(&self, d: Duration)

Advance virtual time by d. Called only by the simulation scheduler, between event deliveries.

pub fn now_ns(&self) -> u64

Current virtual nanoseconds.

pub fn reset(&self)

Rewind virtual time to zero. ONLY sound between independent simulation runs in one process (each run constructs its whole world fresh, so no live state carries Mono values across the reset). Lets a test binary execute the same seeded scenario twice and get bit-identical wall-clock-dependent artifacts (commit timestamps, cap expiries) — the determinism-replay contract.
