Struct FixedClock 

pub struct FixedClock { /* private fields */ }

A controllable clock for tests: pin time to a fixed instant and advance it explicitly. Shareable through &self, so it works behind Arc<dyn Clock>.

Implementations

impl FixedClock

pub fn new(at: Timestamp) -> FixedClock

A clock pinned to at.

pub fn at_unix_millis(millis: i64) -> FixedClock

A clock pinned to millis since the Unix epoch.

pub fn set(&self, at: Timestamp)

Reset the clock to at.

pub fn advance(&self, delta: Duration)

Move the clock forward (or backward, for a negative delta) by delta.
