a.rs

// you can just use
// `pub mod b;`
// if this file is a/mod.rs and
// if you have a file named a/b.rs or a/b/mod.rs
// that contains the contents inside the curly brackets
pub mod b {
  pub static bar: f64 = 1.1;
}

pub static foo: int = 40;

c.rs

use a::b;

pub fn foobar() {
  println!("{}", b::bar);
}

main.rs

use a::b;

mod a;
mod c;

fn main() {
  println!("{}", a::foo);
  c::foobar();
