Crate icalendar

Expand description

A library to generate and parse iCalendars.

Contributions are very welcome.

Structure

Calendars consist of Components
Components are e.g. Event or Todo
Components consist of Propertys
Propertys may have Parameters

let event = Event::new()
    .summary("test event")
    .description("here I have something really important to do")
    .starts(Utc::now())
    .class(Class::Confidential)
    .ends(Utc::now() + Duration::days(1))
    .append_property(Property::new("TEST", "FOOBAR")
              .add_parameter("IMPORTANCE", "very")
              .add_parameter("DUE", "tomorrow")
              .done())
    .done();

let bday = Event::new()
    .all_day(NaiveDate::from_ymd(2023, 3, 15))
    .summary("My Birthday")
    .description(
r#"Hey, I'm gonna have a party
BYOB: Bring your own beer.
Hendrik"#
)
    .done();

let todo = Todo::new().summary("Buy some milk").done();


let mut calendar = Calendar::new();
calendar.push(event);
calendar.push(todo);
calendar.push(bday);

Breaking API Changes in version 0.7.0

Todo::due and Todo::completed now take their date-time argument by value rather than by reference
Todo::completed now requires its chrono::DateTime argument to have exactly chrono::Utc specified as its time zone as mandated by the RFC.
Component::starts, Component::ends and Todo::due now take newly introduced CalendarDateTime (through Into<CalendarDateTime> indirection). This allows callers to define time zone handling. Conversions from chrono::NaiveDateTime and chrono::DateTime<Utc> are provided for ergonomics, the latter also restoring API compatibility in case of UTC date-times.
