| Private modules cannot be publicly re-exported. This error indicates that you | |
| attempted to `pub use` a module that was not itself public. | |
| Erroneous code example: | |
| ```compile_fail,E0365 | |
| mod foo { | |
| pub const X: u32 = 1; | |
| } | |
| pub use foo as foo2; | |
| fn main() {} | |
| ``` | |
| The solution to this problem is to ensure that the module that you are | |
| re-exporting is itself marked with `pub`: | |
| ``` | |
| pub mod foo { | |
| pub const X: u32 = 1; | |
| } | |
| pub use foo as foo2; | |
| fn main() {} | |
| ``` | |
