Function interval 

Source 
pub fn interval(dur: Duration) -> Interval
Expand description

Create an interval tied to the current loop

This is a shortcut for:

ⓘ
Interval::new(instant, &handle()).unwrap()

§Panics

When no loop is running (handle() panics)

(Note: while we technically unwrap() constructor it never fails in current tokio)
