A builder [and parser] for [`rfc5545`](http://tools.ietf.org/html/rfc5545) iCalendar.
You want to help make this more mature? Please talk to me, Pull Requests and suggestions are very welcome.
## Example
Use the builder-pattern to assemble the full calender or event by event.
Display printing produces the rfc5545 format.
```rust
// lets create a calendar
let my_calendar = Calendar::new()
.name("example calendar")
.push(
// add an 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(),
)
.push(
// add a todo
Todo::new()
.summary("groceries")
.description("Buy some milk")
.done(),
)
.push(
// add an all-day event
Event::new()
.all_day(NaiveDate::from_ymd_opt(2016, 3, 15).unwrap())
.summary("My Birthday")
.description("Hey, I'm gonna have a party\nBYOB: Bring your own beer.\nHendrik")
.done(),
)
.push(
// local event with timezone
Event::new()
.starts(CalendarDateTime::from_ymd_hm_tzid(2023, 3, 15, 18, 45, Berlin).unwrap())
.summary("Birthday Party")
.description("I'm gonna have a party\nBYOB: Bring your own beer.\nHendrik")
.done(),
)
.done();
println!("{}", my_calendar);
```
## Parsing
There is a feature called `"parser"` which allows you to read calendars again like this:
```rust
//... continue from previous example
let parsed_calendar = my_calendar.parse::()?;
```
