Struct Base

pub struct Base { /* private fields */ }

Base represents a numeral system with single-character digits.

When creating a new numeral system from a given string slice, the value of each character is its index in the slice, e.g. the first character has value 0, the second has value 1, etc.

If the given slice has at least one duplicate character, parsing will produce an Err.

Examples

use based::*;
 
let base16: based::Base = "0123456789abcdef".parse().unwrap();
assert_eq!("a", base16.encode(10).unwrap());
