morseclock - Yet another not-so-intuitive clock

morseclock allows you to generate a clock visualization inspired by this hackaday post

Usage example

use morseclock::{Clock, Format, MorseExt};
 
// Hour must be in the range [0, 23)
let hour = 16.try_into().unwrap();
// Minute must be in the range [0, 59)
let minute = 47.try_into().unwrap();
 
let clock = Clock::new(hour, minute, Format::Hour12);
 
let time: String = clock
    .into_iter()
    .morse()
    .collect();
 
assert_eq!(time, "--.=----")

How to read the “morsecode”

The mapping generated by the MorseExt iterator extension trait can be interpreted as follows

The string "--.=----" represents the time 4:47.
The character '=' separates the hour-hand from the minute-hand.

On the hour-hand a single '-' stands for a increment of of 3 hours (a quarter rotation of the hand), starting at the 0 o’clock position.
A single '.' stands for an increment of 1 hour.

On the minute-hand, a single '-' stands for a increment of 15 minutes (a quarter rotation of the hand), starting at the 0 o’clock position. A single '.' stands for an increment of 5 minutes.
