Struct ManualClock 

pub struct ManualClock { /* private fields */ }

A clock that only moves when a test moves it.

use chrono::{TimeDelta, Utc};
use turnframe_store::memory::{Clock, ManualClock};

let clock = ManualClock::new(Utc::now());
let start = clock.now();
clock.advance(TimeDelta::seconds(30));
assert_eq!(clock.now(), start + TimeDelta::seconds(30));

Implementations

impl ManualClock

pub fn new(start: DateTime<Utc>) -> ManualClock

A clock stopped at start.

pub fn epoch() -> ManualClock

A clock stopped at the Unix epoch, for tests that only care about order.

pub fn set(&self, instant: DateTime<Utc>)

Moves the clock to instant, forwards or backwards.

A poisoned lock is ignored: the clock is a test fixture and losing its value cannot corrupt anything a store relies on.

pub fn advance(&self, delta: TimeDelta)

Moves the clock forward by delta.
