| bugprone-forward-declaration-namespace |
| ====================================== |
| |
| Checks if an unused forward declaration is in a wrong namespace. |
| |
| The check inspects all unused forward declarations and checks if there is any |
| declaration/definition with the same name existing, which could indicate that |
| the forward declaration is in a potentially wrong namespace. |
| |
| .. code-block:: c++ |
| |
| namespace na { struct A; } |
| namespace nb { struct A {}; } |
| nb::A a; |
| // warning : no definition found for 'A', but a definition with the same name |
| // 'A' found in another namespace 'nb::' |
| |
| This check can only generate warnings, but it can't suggest a fix at this point. |
