Struct VirtualClock 

pub struct VirtualClock { /* private fields */ }

Virtual wall, elapsed and scheduler clocks. Scheduler time is what timers are registered against; it moves only when a history delivers timers, so a silent shift never fires a deliberately held timer.

Implementations

impl VirtualClock

pub fn new(wall_ms: i64) -> Arc<Self>

A clock at wall_ms epoch milliseconds with zero elapsed and scheduler time.

pub fn shift(&self, delta_ms: i64, wall_only: bool)

Move wall (and unless wall_only, elapsed) time without delivering timers.

pub fn shift_ns(&self, delta_ns: i128, wall_only: bool)

shift in nanoseconds; elapsed time saturates at zero.

pub fn pending_timers(&self) -> usize

Timers registered and neither fired nor dropped.

impl VirtualClock

pub fn sleep(&self, duration: Duration) -> BoxFuture<'static, ()>

Register a timer against scheduler time.

Trait Implementations

impl Clock for VirtualClock

fn wall_ms(&self) -> i64

Epoch milliseconds from the application wall clock.

fn elapsed(&self) -> Duration

Monotonic elapsed time since this clock’s origin, with native precision.

fn elapsed_ms(&self) -> i64

Whole-millisecond elapsed reading used by process-local storage.

impl Debug for VirtualClock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
