Quick Example

Date can be initialized from &str or tuple(i32, u32, u32).

extern crate koyomi;

use koyomi::Date;

// Only "Y-m-d" format
let date = Date::parse("2018-01-01").unwrap();
println!("{}", date); // 2018-01-01

// Same as above
let date = Date::from_ymd(2018, 1, 1).unwrap();
println!("{}", date); // 2018-01-01

Calendar can be initialized from Date or CalendarBuilder.

extern crate koyomi;

use koyomi::{Calendar, Date};

// From `Date`
let from = Date::from_ymd(2018, 1, 1).unwrap();
let until = Date::from_ymd(2018, 12, 31).unwrap();
let calendar = Calendar::new(from, until).unwrap().make();

println!("{}", calendar.len()); // 365
println!("{}", calendar[0]); // 2018-01-01

// From `CalendarBuilder`
let calendar = Calendar::build()
    .from("2018-01")
    .until("2018-12")
    .finalize()
    .unwrap()
    .make();
println!("{}", calendar.len()); // 365
println!("{}", calrndar[0]); // 2018-01-01
