/**
 * An abstract service that does the conversion between the internal datepicker `NgbDateStruct` model and
 * any provided user date model `D`, ex. a string, a native date, etc.
 *
 * The adapter is used **only** for conversion when binding datepicker to a form control,
 * ex. `[(ngModel)]="userDateModel"`. Here `userDateModel` can be of any type.
 *
 * The default datepicker implementation assumes we use `NgbDateStruct` as a user model.
 *
 * See the [date format overview](#/components/datepicker/overview#date-model) for more details
 * and the [custom adapter demo](#/components/datepicker/examples#adapter) for an example.
