pub struct DynTimeProvider(Impl);
Expand description

Type-erased SleepProvider and CoarseTimeProvider

Useful where time is needed, but we don’t want a runtime type parameter.

Implementations§

Source§

impl DynTimeProvider

Source

pub fn new<R: SleepProvider + CoarseTimeProvider>(runtime: R) -> Self

Create a new DynTimeProvider from a concrete runtime type

impl SleepProvider for DynTimeProvider

Source§

type SleepFuture = Pin<Box<dyn Future<Output = ()> + Send>>

Source§

fn wallclock(&self) -> SystemTime

Source§

fn block_advance<R: Into<String>>(&self, reason: R)

Signify that a test running under mock time shouldn’t advance time yet, with a given unique reason string. This is useful for making sure (mock) time doesn’t advance while things that might require some (real-world) time to complete do so, such as spawning a task on another thread. Read more
Source§

fn release_advance<R: Into<String>>(&self, reason: R)

Signify that the reason to withhold time advancing provided in a call to block_advance no longer exists, and it’s fine to move time forward if nothing else is blocking advances. Read more
Source§

fn allow_one_advance(&self, duration: Duration)

Allow a test running under mock time to advance time by the provided duration, even if the above block_advance API has been used. Read more
Source§

fn sleep( &self, duration: Duration, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'static>>

Return a future that will be ready after duration has elapsed.
