// AutofillDriver is Autofill's lowest-level abstraction of a frame that is
// shared among all platforms.
//
// Most notably, it is a gateway for all communication from the browser code to
// the DOM, or more precisely, to the AutofillAgent (which are different classes
// of the same name in non-iOS vs iOS).
//
// The reverse communication, from the AutofillAgent to the browser code, goes
// through mojom::AutofillDriver on non-iOS, and directly to AutofillManager on
// iOS.
//
// Events for browser-internal communication do *NOT* belong here. Use
// AutofillManager::Observer instead.
//
// An AutofillDriver corresponds to a frame, rather than a document, in the
// sense that it may survive navigations.
//
// AutofillDriver has two implementations:
// - AutofillDriverIOS for iOS,
// - ContentAutofillDriver for all other platforms.
//
// An AutofillDriver's lifetime must be contained by the associated frame,
// web::WebFrame on iOS and content::RenderFrameHost on non-iOS. This is ensured
// by the AutofillDriverIOSFactory and ContentAutofillDriverFactory,
// respectively, which own the AutofillDrivers.
