binexp

binexp provides a PowerOfTwo struct that you can create from any valid power of two integer.
You can use PowerOfTwo as a safe way to represent powers of two in your code.

Examples

use std::convert::TryFrom;
use binexp::PowerOfTwo;

assert!(PowerOfTwo::try_from(1).is_ok());
assert!(PowerOfTwo::try_from(2).is_ok());
assert!(PowerOfTwo::try_from(3).is_err());

let four = PowerOfTwo::try_from(4).unwrap();
assert_eq!(four.to_string(), "2^2 (4)");

let eight: PowerOfTwo = 8i8.try_into().unwrap();
assert_eq!(eight.to_string(), "2^3 (8)");
