| A file wasn't found for an out-of-line module. | |
| Erroneous code example: | |
| ```compile_fail,E0583 | |
| mod file_that_doesnt_exist; // error: file not found for module | |
| fn main() {} | |
| ``` | |
| Please be sure that a file corresponding to the module exists. If you | |
| want to use a module named `file_that_doesnt_exist`, you need to have a file | |
| named `file_that_doesnt_exist.rs` or `file_that_doesnt_exist/mod.rs` in the | |
| same directory. |
