# infer_module_app(Mod)

    -spec infer_module_app(module()) -> no_app | {app, atom()}.

Infer application containing the given module.

It's expected that modules which are not preloaded and don't match the `<app>/ebin/<mod>.beam` path pattern will NOT have an app name inferred properly. `no_app` is returned in such cases.
