Validator
import type { Validator } from "https://aws-api.deno.dev/v0.4/services/appconfig.ts?docs=full";
A validator provides a syntactic or semantic check to ensure the configuration that you want to deploy functions as intended. To validate your application configuration data, you provide a schema or an Amazon Web Services Lambda function that runs against the configuration. The configuration deployment or update can only proceed when the configuration data is valid.
