Return the day of the week a specific date falls on (uses Tomohiko Sakamoto's algorithm).
Add this to your Cargo.toml
:
[dependencies]
dow = "0.1"
and this to your crate root:
extern crate dow;
use dow::Day;
and then you can use it as follows:
let day = dow::dow(2017, 7, 2);
assert_eq!(day, Day::Sunday);
