There are multiple ways to create a new
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));
Instant to calculate how long a function took to run:
Durationtype to represent a span of time, typically used for system timeouts.
- A measurement of a monotonically nondecreasing clock. Opaque and useful only with
- A measurement of the system clock, useful for talking to external entities like the file system or other processes.
- An error returned from the
SystemTime, used to learn how far in the opposite direction a system time lies.
- An error which can be returned when converting a floating-point value of seconds into a
- An anchor in time which can be used to create new
SystemTimeinstances or learn about where in time a
