Struct ManualClock 

pub struct ManualClock { /* private fields */ }

Deterministic clock for tests and loom models.

The clock starts at the Instant captured at construction time and advances only when callers invoke ManualClock::advance. Internally the offset is stored as nanoseconds in an AtomicU64, so the clock is Send + Sync and can be shared across threads (or loom-modelled threads) without further wrapping.

Implementations

impl ManualClock

pub fn new() -> Self

Creates a clock anchored at the calling-thread’s current Instant with zero offset.

pub fn advance(&self, delta: Duration)

Advances the clock by delta. Saturates at u64::MAX nanoseconds (~584 years), which is plenty for any realistic test horizon.

Trait Implementations

impl Clock for ManualClock

fn now(&self) -> Instant

Returns a monotonic instant. Successive calls must never return an earlier instant than a prior call.

impl Debug for ManualClock

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

Formats the value using the given formatter.

impl Default for ManualClock

fn default() -> Self

Returns the “default value” for a type.
