How to get debug! to work in a sub process (child)

help
1

Another noob question. I need to only have console statements appear if I use
RUST_LOG=debug ./main
when running a program

I have
-- main.rs
------ sub1.rs
------ sub2.rs

In my main.rs I have
#[macro_use]
extern crate log;
and it works fine

If I use debug!("Debug message") here there is no problem

However, in sub1.rs I use debug! and get an error of
error: cannot find macro debug in this scope

Is there a preamble of some sort I need in sub1.rs like
use log::{info, warn,debug}
which doesn't work.
