Struct MockClock 

pub struct MockClock { /* private fields */ }

Test clock: a manually-advanced nanosecond counter.

MockClock is a cloneable handle over a shared counter — clone it, hand one clone to ExecutorBuilder::clock and keep the other to drive time from the test (or from inside a task body). Both clones observe the same counter.

Advancing the clock from inside a cyclic task body is the idiomatic pattern: the body “spends” a precise number of nanoseconds, which the telemetry fold then reads back as the cycle’s took (and, across cycles, as the measured period feeding jitter and lateness).

Implementations

impl MockClock

pub fn new() -> Self

Construct a mock clock reading 0.

pub fn advance(&self, delta_ns: u64) -> u64

Advance the clock by delta_ns, returning the new value.

pub fn set(&self, ns: u64)

Set the clock to the absolute value ns.

pub fn now(&self) -> u64

Read the current value.

Trait Implementations

impl Clone for MockClock

fn clone(&self) -> MockClock

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MockClock

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

impl Default for MockClock

fn default() -> MockClock

Returns the “default value” for a type.

impl MonotonicClock for MockClock

fn now_nanos(&self) -> u64

Nanoseconds since this clock’s epoch. Monotonic non-decreasing.
