Struct ManualClock 

pub struct ManualClock { /* private fields */ }

A physical clock a test moves by hand.

The clock holds one instant and returns it until the test changes it. Every method takes &self, so a test can hold the clock in an Arc and still move it while an HlcClock reads it.

Implementations

impl ManualClock

pub fn new(now: WallMicros) -> Self

A clock stopped at now.

pub fn set(&self, now: WallMicros)

Moves the clock to now. The new instant can be before the old one, which is how a test models a clock that jumps backwards.

pub fn advance(&self, by: Time)

Moves the clock forward by by. A negative extent moves it backwards.

Trait Implementations

impl Debug for ManualClock

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

Formats the value using the given formatter.

impl PhysicalClock for ManualClock

fn now_micros(&self) -> i64

The current wall-clock time, in microseconds since the Unix epoch.
