based

based provides support for custom numerical bases. based does not support multi-character digits.

Example

use based::{Base, NumeralSystem};

let base16: Base = "0123456789abcdef".parse().unwrap();
let val: usize = base16.decode("10").unwrap();
assert_eq!(val, 16);
assert_eq!(base16.encode(16 as usize).unwrap(), "10")
