   1 Something other than a module was found in visibility scope.
   2
   3 Erroneous code example:
   4
   5 ```compile_fail,E0577,edition2018
   6 pub struct Sea;
   7
   8 pub (in crate::Sea) struct Shark; // error!
   9
  10 fn main() {}
  11 ```
  12
  13 `Sea` is not a module, therefore it is invalid to use it in a visibility path.
  14 To fix this error we need to ensure `Sea` is a module.
  15
  16 Please note that the visibility scope can only be applied on ancestors!

  18 ```edition2018
  19 pub mod Sea {
  20     pub (in crate::Sea) struct Shark; // ok!
  21 }
  22
  23 fn main() {}
  24 ```
