extern crate pg_interval;
use pg_interval::Interval;
fn main() {
let interval = Interval::from_postgres(
"1 years 1 months 1 days 1 hours"
).unwrap();
let output = interval.to_iso_8601();
assert_eq!(String::from("P1Y1M1DT1H"), output);
let interval = Interval::from_std_duration(
std::time::Duration::from_secs(3_661)
).unwrap();
assert_eq!(Interval::new(0, 0, 3_661_000_000), interval);
