Include file in root and other files

Let's say I have this file structure:
src >
- include.rs
- main.rs
- other.rs

I want to include include.rs in main.rs and other.rs. I can do mod include in main.rs, but what do I do in other.rs to include it there too?

use crate::include;

mod behaves the same way as fn, struct and enum. It crates a thing in one place, and then you use it from other places.
