A library for creating iCalendar files as specified in RFC5545 and RFC7986.

Installation

To use this library add the library as a dependency in your Cargo.toml:

[dependencies]
ics = "0.2"

Optionally you can disable default features.

[dependencies.ics]
version = "0.2"
default-features = false

Features

• fast_text (enabled by default): faster text processing in methods like escape_text but pulls in dependencies (regex and lazy_static)
• rfc7986 (enabled by default): adds properties from the newer specification

Usage

extern crate ics;

use ics::properties::{Categories, Description, DtEnd, DtStart, Organizer, Status, Summary};
use ics::{escape_text, Event, ICalendar};
use std::fs::File;
use std::io::Write;

fn main() {
    // create new iCalendar object
    let mut calendar = ICalendar::new("2.0", "-//xyz Corp//NONSGML PDA Calendar Version 1.0//EN");

    // create event which contains the information regarding the conference
    let mut event = Event::new("b68378cf-872d-44f1-9703-5e3725c56e71", "19960704T120000Z");
    // add properties
    event.push(Organizer::new("mailto:jsmith@example.com"));
    event.push(DtStart::new("19960918T143000Z"));
    event.push(DtEnd::new("19960920T220000Z"));
    event.push(Status::new("CONFIRMED"));
    event.push(Categories::new("CONFERENCE"));
    event.push(Summary::new("Networld+Interop Conference"));
    // values that are "TEXT" must be escaped (only if the text contains a comma,
    // semicolon or backlash)
    event.push(Description::new(escape_text(
        "Networld+Interop Conference and Exhibit\n\
         Atlanta World Congress Center\n\
         Atlanta, Georgia"
    )));
    // add event to calendar
    calendar.add_event(event);

    // write calendar to file
    let data = calendar.to_string();
    let mut f = File::create("icalendar.ics").expect("Unable to create file");
    f.write_all(data.as_bytes()).expect("Unable to write data");
