Struct ValueUnit 

pub struct ValueUnit {
    pub value: f64,
    /* private fields */
}

Allways use the ValueUnit macro to create this struct.
This struct implements all basic arithmatic methods and a power method.
It should be noted however that add, subtract, addassign and subassign will panic if the units are not identical.
Use try_add and try_sub if you want a Result.
root will also panic if not all units have a power which is a multiple of the power.

use value_unit::*;
let d = ValueUnit!(10 m);
let t = ValueUnit!(5 s);
assert_eq!(d.try_add(&t), Err("Units m and s don't match".to_string()));

Fields

value: f64
