Crate icalendar_duration

A parser implementation for durations as defined in RFC5545.

These are mostly used for alarms, to indicate their time relative to the time of an event or todo.

For convenience, Rfc5545Duration implements Add for icalendar::DatePerhapsTime, chrono::DateTime and chrono::naive::NaiveDateTime.

Example

use chrono::TimeZone;
use chrono::Utc;

let duration = icalendar_duration::parse("PT24H")?;
let dt = Utc.ymd(2022, 9, 1).and_hms(22, 9, 14);

assert_eq!(dt + duration, Utc.ymd(2022, 9, 2).and_hms(22, 9, 14));
