Crate signrel 

This crate provides the SignRel trait which maps relationships between integers that only differ by signedness. For example, both a and b in this example have the type usize:

use signrel::SignRel;

let a: <isize as SignRel>::Unsigned = 17;
let b: <usize as SignRel>::Unsigned = 17;

assert_eq!(17usize, a);
assert_eq!(17usize, b);
