Can you share private functions amongst mods within a crate?

I'm building out a crate and for use across several applications I'm working on. At the moment, I have a handful of functions that serve as 'helpers' for the rest of the crate which I would like to expose across my crate but not to the applications. Is there a way to do this? A middle ground between public and private?

example:

// lib.rs
pub mod mod_a;
pub mod mod_b;

// mod_a.rs, mod_b.rs
use helpers::bar;

pub fn foo() {
   bar()
}

...

// helpers.rs
pub fn bar(x: i64) {
   return(x+1)
}

I would like to expose the function bar to mod_a and mod_b, without exporting it from my crate

Use pub(crate) while declaring items.
