Usage

use std::time::{Duration, Instant};

fn main() {
    // Parsing to get a duration.
    assert_eq!(relhu::parse_duration("5s").unwrap(), Duration::from_secs(5));
    assert_eq!(relhu::parse_duration("100 us").unwrap(), Duration::from_micros(100));

    // Parsing to get an instant in the future.
    let now = Instant::now();
    assert_eq!(relhu::parse_with_instant("15m later", now).unwrap(), now + Duration::from_secs(15 * 60));
    assert_eq!(relhu::parse_with_instant("+55ms", now).unwrap(), now + Duration::from_millis(55));

    // Parsing to get an instant in the past.
    let now = Instant::now();
    assert_eq!(relhu::parse_with_instant("20ns ago", now).unwrap(), now - Duration::from_nanos(20));
    assert_eq!(relhu::parse_with_instant("- 5 days", now).unwrap(), now - Duration::from_secs(5 * 60 * 60 * 24));
