# SITY for SI (Intenational System Unit) Typing
This library makes SI types available in Rust. International System Conformance is checked at compile time.


## Example

```
pub use sity::*;
use std::mem;

fn main() {
    let a = centi_metre(3.0);
    let b = centi_metre(4.0);
    let c = second(2.0);
    let si_value = a * b / c;
    let si_value_size = mem::size_of_val(&si_value);
    // let x = a + c; // Compile time Error

    println!("si_value = {} (size = {})", si_value, si_value_size);
    let pure_value = si_value.value();
    let pure_value_size = mem::size_of_val(&pure_value);
    println!("pure_value = {} (size = {})", pure_value, pure_value_size);    
}
```
