Struct floating_duration::TimeFormat

pub struct TimeFormat<T: Borrow<Duration>>(pub T);

A formatting newtype for providing a Display implementation. This format is meant to be used for printing performance measurements.

Behaviour

• secs > 0 => seconds with precision 3
• secs > 0.001 => milliseconds with precision 3
• secs > 0.000_001 => microseconds with precision 3
• otherwise => nanoseconds

By default the duration is formatted using abbreviated units (e.g. 1.234ms). If the the format string is specified with the alternate flag {:#}, the duration is formatted using the full unit name instead (e.g. 1.234 milliseconds).

Examples

use std::time::Duration;
use floating_duration::TimeFormat;

let dur = Duration::new(0, 461_933);
let formatted = format!("{}", TimeFormat(dur));
assert_eq!(formatted, "461.933µs");
let alternate = format!("{:#}", TimeFormat(dur));
assert_eq!(alternate, "461.933 microseconds");
