Result of a delete mutation?

What should be the result of a delete mutation in Graphql? I'm using the graphql-ruby gem. Here's an example of my mutation, but I'm just not sure what I should be returning as the response.

Mutations::Brands::Delete = GraphQL::Relay::Mutation.define do
  name "DeleteBrand"
  description "Delete a brand"

  input_field :id, types.ID

  # return_field ??

  resolve ->(object, inputs, ctx) {
    brand = Brand.find(inputs[:id])
    brand.destroy
  }
end
