Crate unitage

Description

Yet one more another unit/dimension support library for rust.

This package lets you write units of physical quantities in the same way you always write it.

Usage

use ::unitage:: { *, predefined::* };

fn bmi(hight: Length<f64>, weight: Mass<f64>) -> f64 {
    let bmi = weight / hight / hight;

    unit!("kg/m2").value(bmi)
}

let h = pq!(5f64, "ft.") + pq!(8f64, "in.");
let w = pq!(200f64, "lb");

assert_eq!(bmi(h, w), 30.409583894427303); // Lose weight!!

Generate PhysicalQuantity from value and unit string.

unit

Generate Unit from unit string.

Structs

Conv

linear convertion coefficients target_unit = a * source_unit_value + b

Dim

Static (compile time) Dimension.

DynDim

Dynamic (runtime) Dimension

Frac

Representation of fractional value.

PhysicalQuantity

Represents physical quantity

Unit

Representation of Unit

Traits
