Temporal quantification.


There are multiple ways to create a new Duration:

let five_seconds = Duration::from_secs(5);
assert_eq!(five_seconds, Duration::from_millis(5_000));
assert_eq!(five_seconds, Duration::from_micros(5_000_000));
assert_eq!(five_seconds, Duration::from_nanos(5_000_000_000));

let ten_seconds = Duration::from_secs(10);
let seven_nanos = Duration::from_nanos(7);
let total = ten_seconds + seven_nanos;
assert_eq!(total, Duration::new(10, 7));


A Duration type to represent a span of time, typically used for system timeouts.
An error which can be returned when converting a floating-point value of seconds into a Duration.
