Struct SimClock 

pub struct SimClock { /* private fields */ }

Deterministic simulation clock for tests.

Time is frozen at seed_ms until the test calls SimClock::advance_ms or SimClock::set_ms. All operations on the internal counter use relaxed atomics — SimClock is not intended for concurrent mutation, only for sequential test control.

Implementations

impl SimClock

pub fn from_seed(seed_ms: u64) -> Self

Create a clock frozen at seed_ms milliseconds since the Unix epoch.

pub fn advance_ms(&self, delta_ms: u64)

Move the clock forward by delta_ms milliseconds.

pub fn set_ms(&self, ms: u64)

Jump the clock to an absolute time (milliseconds since Unix epoch).

Trait Implementations

impl Clock for SimClock

fn now_unix_millis(&self) -> u64

Returns the current time as milliseconds since the Unix epoch.
