OperationCallback<E extends Identifiable> = Future<ManageOperation> Function(E updatedIdentifiable, List<E> list)

The returned ManageOperation determines whether the updatedIdentifiable will be merged, removed or ignored from the list.

typedef OperationCallback<E extends Identifiable> = Future<ManageOperation>
    Function(E updatedIdentifiable, List<E> list);
