[−][src]Struct futures_ticker::Ticker
Yields the current time in regular intervals.
Tickers are an asynchronous notification mechanism which deliver the "current" time in regular intervals (a "tick"). In case any ticks were missed, they will be skipped, and only the nearest upcoming tick is delivered.
Implementations
impl Ticker[src]
pub fn new(interval: Duration) -> Ticker[src]
Constructs a ticker that goes off once per interval. It
is scheduled to deliver the first tick at interval from now.
pub fn new_with_next(interval: Duration, first_in: Duration) -> Ticker[src]
Constructs a ticker that goes off once per interval. The first
tick is scheduled to arrive after first_in elapses.
pub fn next_tick(&self) -> Instant[src]
Returns the next Instant at which the Ticker will be ready.
pub fn next_tick_from(&self, now: Instant) -> Instant[src]
Answers the hypothetical question, "at Instant now, when
would the next tick go off?"
This function is useful mainly for tests. Use
Ticker::next_tick for real use cases instead.
