First Example in https://doc.rust-lang.org/reference/visibility-and-privacy.html

   Compiling playground v0.0.1 (/playground)
error[E0432]: unresolved import `crate_helper_module`
  --> src/lib.rs:22:9
   |
22 |     use crate_helper_module;
   |         ^^^^^^^^^^^^^^^^^^^ no external crate `crate_helper_module`

This line should be changed to

use crate::crate_helper_module;

It is currect for the 2015 edition.

I posted #1041 to change things to default to 2018 to fix this.
