Unit Types

DO NOT USE IN PRODUCTION! This is a learning project and is not intended for production use. Some of the conversion numbers were automatically filled out by GitHub Copilot and have not yet been validated.

I have not yet determined how far I will take this project. Forks or contributions are welcome.

The unit_types crate is a dimensionally aware type system for Rust.

Example:

use unit_types::prelude::*; // brings in "unit"
use unit_types::Length;
let x = Length::Kilometers(1.0);
let y = Length::Meters(200.0);
assert_eq!(x - y, Length::Meters(800.0));
assert_eq!(x + y, Length::Meters(1200.0));

let z = 2.0 * (x + y); // should be in Kilometers
assert_eq!(z.value(), 2.4);
assert_eq!(z.to(unit::Meters).value(), 2400.0);

lib.rs:

The unit names are all namespaced under unit to avoid conflicts with other names. Unit names come from their respective modules and are re-exported from lib.rs. Within a given dimension module, unit enums are defined in the form DimensionUnit. For example, the length module has LengthUnit, the time module has TimeUnit, etc.
