class GraphQL::Schema::Validator::InclusionValidator
You can use this to allow certain values for an argument.
Usually, a {GraphQL::Schema::Enum} is better for this, because it’s self-documenting.
@example only allow certain values for an argument
argument :favorite_prime, Integer, required: true, validates: { inclusion: { in: [2, 3, 5, 7, 11, ... ] } }
