   1 Private items cannot be publicly re-exported. This error indicates that you
   2 attempted to `pub use` a type or value that was not itself public.
   3
   4 Erroneous code example:
   5
   6 ```compile_fail,E0364
   7 mod a {
   8     fn foo() {}
   9
  10     mod a {
  11         pub use super::foo; // error!
  12     }
  13 }
  14 ```
  15
  16 The solution to this problem is to ensure that the items that you are
  17 re-exporting are themselves marked with `pub`:
  18
  19 ```
  20 mod a {
  21     pub fn foo() {} // ok!
  22
  23     mod a {
  24         pub use super::foo;
  25     }
  26 }
  27 ```
