# Creates a bookmark for a registered bookmarkable (see Bookmark.register_bookmarkable
# and RegisteredBookmarkable for details on this).
#
# Only allows creation of bookmarks for records the user
# can access via Guardian.
#
# Any ActiveModel validation errors raised by the Bookmark model are
# hoisted to the instance of this class for further reporting.
#
# Before creation validations, after create callbacks, and after delete
# callbacks are all RegisteredBookmarkable specific and should be defined
# there.
#
# @param [Integer] bookmarkable_id The ID of the ActiveRecord model to attach the bookmark to.
# @param [String] bookmarkable_type The class name of the ActiveRecord model to attach the bookmark to.
# @param [String] name A short note for the bookmark, shown on the user bookmark list
# and on hover of reminder notifications.
# @param reminder_at The datetime when a bookmark reminder should be sent after.
# Note this is not the exact time a reminder will be sent, as
# we send reminders on a rolling schedule.
# See Jobs::BookmarkReminderNotifications
# @params options Additional options when creating a bookmark
# - auto_delete_preference:
# See Bookmark.auto_delete_preferences,
# this is used to determine when to delete a bookmark
# automatically.
