As it stands, our crate is far from finished. However, there is enough code in there to see whether it actually runs.
Code for this section is in Chapter10/first_run_out.
Our initial code looks like this:
extern crate mathslib;
use mathslib::conversions::temperature::*;
fn main()
{
let mut testval = celcius_to_fahrenheit(100f32);
println!("100C = {}F", testval.1); // should be 212
}
When we build this, we get the following:

This stands to reason; we're asking the code to include a library that it has no clue about.
