Function date_differencer::date_diff

pub fn date_diff<Tz: TimeZone>(
    from: DateTime<Tz>,
    to: DateTime<Tz>
) -> DateDiffResult

Calculate the difference between two DateTime instances.

Example

use chrono::prelude::*;
use date_differencer::{date_diff, DateDiffResult};

let date = Local.with_ymd_and_hms(2000, 1, 1, 0, 0, 0).unwrap();
let date_after_1_year_1_day =
    Local.with_ymd_and_hms(2001, 1, 2, 0, 0, 0).unwrap();

assert_eq!(
    DateDiffResult {
        years: 1,
        days: 1,
        ..DateDiffResult::default()
    },
    date_diff(date, date_after_1_year_1_day)
);
