Rust - How can I call functions from my src folder to code in my examples folder?

Question

If I have this function in src/test.rs

pub fn print_something(){
    println!("Something");
}

how can I call it in the example/test.rs ?

I've tried with extern crate, mod, use but none of these worked.

First, you have to declare the test module in src/lib.rs:

pub mod test;

Then, inside examples/test.rs, just use it as a library:

crate_name::test::print_something(); // Replace `crate_name` by the crate name
