// `ScopedAutofillManagersObservation` is a helper to reduce boilerplate when
// observing all `AutofillManagers` of a `WebContents`. Instead of having to
// implement both `ContentAutofillDriverFactory`'s and `AutofillManager`'s
// observer interfaces, the consumer now only needs to implement
// `AutofillManager::Observer` and add a member variable of this type.
//
// Example:
// class AutofillInformationConsumer : public AutofillManager::Observer {
//  public:
//   AutofillInformationConsumer(content::WebContents* contents) {
//     autofill_managers_observation.Observe(contents);
//   }
//
//   // AutofillManager::Observer:
//   void OnAfterLanguageDetermined(AutofillManager& manager) {
//     // Do something.
//   }
//
//  private:
//   ScopedAutofillManagersObservation autofill_managers_observation_{this};
// };
