Variables

var WallClock wallClock

Functions

func Alarm

func Alarm(c Clock, t time.Time) <-chan time.Time

Alarm returns a channel that will have the time sent on it at some point after the supplied time occurs.

This is short for c.After(t.Sub(c.Now())).

Types

type Clock

type Clock interface {

	// Now returns the current clock time.
	Now() time.Time

	// After waits for the duration to elapse and then sends the
	// current time on the returned channel.
	After(time.Duration) <-chan time.Time
}

Clock provides an interface for dealing with clocks.
