# (This is for specifying mutually exclusive sets of arguments.)

# @example Require exactly one of these arguments
#
# field :update_amount, IngredientAmount, null: false do
# argument :ingredient_id, ID, required: true
# argument :cups, Integer, required: false
# argument :tablespoons, Integer, required: false
# argument :teaspoons, Integer, required: false
# validates required: { one_of: [:cups, :tablespoons, :teaspoons] }
# end

# @example Require one of these _sets_ of arguments
#
# field :find_object, Node, null: true do
# argument :node_id, ID, required: false
# argument :object_type, String, required: false
# argument :object_id, Integer, required: false
# # either a global `node_id` or an `object_type`/`object_id` pair is required:
# validates required: { one_of: [:node_id, [:object_type, :object_id]] }
# end
#
# @example require _some_ value for an argument, even if it's null
# field :update_settings, AccountSettings do
# # `required: :nullable` means this argument must be given, but may be `null`
# argument :age, Integer, required: :nullable
