Struct ManualClock 

pub struct ManualClock { /* private fields */ }

Manual clock for tests. Wrap Arc<ManualClock>; a test that wants to advance the clock holds a handle next to the RateBudget it feeds into.

Uses a Mutex<Instant> rather than atomics because the Instant type is not trivially atomic across platforms and a test-only code path is not where cycle-shaving matters.

Implementations

impl ManualClock

pub fn new() -> Arc<Self>

Seed at an arbitrary instant. Callers should treat the seed as opaque — only deltas matter.

pub fn advance(&self, d: Duration)

Advance the clock by d. Useful for advance(Duration:: from_secs(5)) to let the bucket refill, etc.

Trait Implementations

impl Clock for ManualClock

fn now(&self) -> Instant

A monotonically-nondecreasing instant. Callers must rely on the return values’ ordering, not their absolute origin.

impl Debug for ManualClock

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

Formats the value using the given formatter.
