Function pathfinding::utils::absdiff

pub fn absdiff<T>(x: T, y: T) -> T where
    T: Sub<Output = T> + PartialOrd, 

Compute the absolute difference between two values.

Example

The absolute difference between 4 and 17 as unsigned values will be 13.

use pathfinding::utils::absdiff;

assert_eq!(absdiff(4u32, 17u32), 13u32);
assert_eq!(absdiff(17u32, 4u32), 13u32);
