dollcode

tiny dollcode implementation

example

use dollcode;

let encoded = dollcode::encode(0x464383c);
assert_eq!(encoded, String::from("▖▖▘▌▌▖▘▖▌▖▖▖▘▘▖▘▖"));

// decoding can fail if the input isn't well-formatted, so it returns an Option
let decoded = dollcode::decode(&encoded);
assert_eq!(decoded, Some(0x464383c));
assert_eq!(dollcode::decode("invalid"), None);
