Module tokio_timer::timer [−][src]
Timer implementation.
This module contains the types needed to run a timer.
The Timer
type runs the timer logic. It holds all the necessary state
to track all associated Delay
instances and delivering notifications
once the deadlines are reached.
The Handle
type is a reference to a Timer
instance. This type is
Clone
, Send
, and Sync
. This type is used to create instances of
Delay
.
The Now
trait describes how to get an Instant
representing the
current moment in time. SystemNow
is the default implementation, where
Now::now
is implemented by calling Instant::now
.
Timer
is generic over Now
. This allows the source of time to be
customized. This ability is especially useful in tests and any environment
where determinism is necessary.
Note, when using the Tokio runtime, the Timer
does not need to be manually
setup as the runtime comes pre-configured with a Timer
instance.
