Crate binexp

A library for working with power of two numbers. Using the PowerOfTwo struct can be useful for validation purposes, when you want to make sure that a number is a power of two. PowerOfTwo implements TryFrom for all integer types, so you can convert any integer into a PowerOfTwo instance.

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