}

GQLTypeResolver

Defines a new TypeResolver for the given type name and scope.

class UserTypeResolver : TypeResolver {
    override fun getType(env: TypeResolutionEnvironment?): GraphQLObjectType = TODO("implement")
}

GQLScalar

    override fun serialize(dataFetcherResult: Any): String = TODO("implement")
}
