# This is a basic implementation of the Notification service using Amazon SNS.
# The expected usage is as follows :
#   notification_service = DispatchRider::NotificationServices::AwsSns.new
#   notification_service.publish(:to => [:foo, :oof], :message => {:subject => "bar", :body => "baz"})
module DispatchRider
  module NotificationServices

      def notifier_builder
        AWS::SNS
      rescue NameError
        raise AdapterNotFoundError.new(self.class.name, 'aws-sdk')
      end

        channels(options[:to]).each do |channel|

            channel.publish(serialize(options[:message]))

      # not really happy with this, but the notification service registrar system is way too rigid to do this cleaner
      # since you only can have one notifier for the whole service, but you need to create a new one for each region
