/// Features for serving HTTP requests on Google Cloud Platform.
///
/// This library provides functions to run a `shelf` server that handles
/// requests in a way that is compatible with Google Cloud environments like
/// Cloud Run and Cloud Functions. It includes middleware for logging requests
/// in the format expected by Google Cloud Logging.
///
/// ## Example
///
/// ```dart
/// import 'package:google_cloud/google_cloud.dart';
/// import 'package:shelf/shelf.dart';
///
/// Future<void> main() async {
///   final handler = const Pipeline()
///       .addMiddleware(createLoggingMiddleware())
///       .addHandler(_helloWorldHandler);
///
///   await serveHandler(handler);
/// }
///
/// Response _helloWorldHandler(Request request) {
///   return Response.ok('Hello, World!');
/// }
/// ```
///
/// {@canonicalFor bad_configuration_exception.BadConfigurationException}
/// {@canonicalFor bad_request_exception.BadRequestException}
/// {@canonicalFor http_logging.badRequestMiddleware}
/// {@canonicalFor http_logging.cloudLoggingMiddleware}
/// {@canonicalFor http_logging.createLoggingMiddleware}
/// {@canonicalFor http_logging.currentLogger}
/// {@canonicalFor serve.listenPortFromEnvironment}
/// {@canonicalFor serve.serveHandler}
/// {@canonicalFor terminate.waitForTerminate}
