Struct base::clock::FakeClock

pub struct FakeClock {
    epoch: Instant,
    ns_since_epoch: u64,
    deadlines: Vec<(u64, Event)>,
}

A fake clock that can be used in tests to give exact control over the time. For a code example, see the tests in base/src/timer.rs.

Fields

epoch: Instant

ns_since_epoch: u64

deadlines: Vec<(u64, Event)>

Implementations

impl FakeClock

pub fn new() -> Self

pub fn now(&self) -> Instant

Get the current time, according to this clock.

pub fn nanos(&self) -> u64

Get the current time in ns, according to this clock.

pub fn add_event(&mut self, deadline_ns: u64, descriptor: Event)

Register the event descriptor for a notification when self’s time is |deadline_ns|. Drop any existing events registered to the same raw descriptor.

pub fn add_ns(&mut self, ns: u64)
