mag 0.3.0

Measurement unit conversions (magnitude!)
Documentation

Mag is a library for dealing with units of measure. Magnitude!

Highlights

  • Easy to understand and use
  • No external dependencies
  • Fast compile time
  • Units are not discarded when creating quantities

Example

use mag::{length::{ft, m, mi}, time::{h, s}};

let a = 1.0 * ft; // Length<ft>
let b = a.to::<m>(); // convert to Length<m>
let c = 30.0 * s; // Period<s>
let d = 60.0 / s; // Frequency<s>
let e = 55.0 * mi / h; // Speed<mi, h>

assert_eq!(a.to_string(), "1 ft");
assert_eq!(b.to_string(), "0.3048 m");
assert_eq!(c.to_string(), "30 s");
assert_eq!(d.to_string(), "60 ㎐");
assert_eq!(e.to_string(), "55 mi/h");

Room For Improvement

  • Small set of quantities and units implemented
  • Quantities are f64 only
