| Something other than a module was found in visibility scope. | |
| Erroneous code example: | |
| ```compile_fail,E0577,edition2018 | |
| pub enum Sea {} | |
| pub (in crate::Sea) struct Shark; // error! | |
| fn main() {} | |
| ``` | |
| `Sea` is not a module, therefore it is invalid to use it in a visibility path. | |
| To fix this error we need to ensure `sea` is a module. | |
| Please note that the visibility scope can only be applied on ancestors! | |
| ```edition2018 | |
| pub mod sea { | |
| pub (in crate::sea) struct Shark; // ok! | |
| } | |
| fn main() {} | |
| ``` |
