XRUnits

XRUnits is a unit library

My english is NOT very good !!

Motivation

We usually use some real-world unit. If we need to develop a program to deal with these units, like creating a downloader which need to calculate the data transfer speed or set the frequency of MCU,we need do lots of duplicate works to convert these unit, so I want to develop a unit library with STRONG TYPE and Easily using to deal with these situations.

Details

To avoid duplicate code,I use lots of macro to automatically generate code.

Examples

To create 2Kg

let mass = 2.kg();

Convert it to ton and gram

let mass : Ton = 2.kg().cast_to();
let mass : Gram = mass.cast_to();

Print to screen

println!("time:{}",3.sec()); //time:3s

Calculate the Frequency from Period

let us = 1.us();
let mhz : Megahertz = us.into_frequency();
