Struct ManualClock 

pub struct ManualClock { /* private fields */ }

A clock that moves only when told to.

It starts at the moment of construction and never goes backwards: set_elapsed to an earlier point is ignored, so out-of-order inputs cannot make a duration negative.

Implementations

impl ManualClock

pub fn new() -> Self

A clock whose wall time starts at the current system time.

pub fn starting_at(system_origin: SystemTime) -> Self

A clock whose wall time starts at system_origin (for example, the first timestamp of a recording).

pub fn advance(&self, by: Duration)

Move the clock forward by by.

pub fn set_elapsed(&self, elapsed: Duration)

Move the clock to elapsed after its origin, if that is later than where it is now.

pub fn elapsed(&self) -> Duration

Time elapsed since the clock’s origin.

Trait Implementations

impl Clock for ManualClock

fn now(&self) -> Instant

The current monotonic instant. Use for durations and deadlines.

fn system_time(&self) -> SystemTime

The current wall-clock time. Use for timestamps that leave the process.

fn since(&self, earlier: Instant) -> Duration

Time elapsed since earlier, per this clock. Saturates at zero.

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.
