An idiomatic C++ client library for theServerless VPC Access API, a service to API for managing VPC access connectors.
While this library isGA, please note Google Cloud C++ client libraries donotfollowSemantic Versioning.
Quickstart
The following shows the code that you'll run in thegoogle/cloud/vpcaccess/quickstart/directory, which should give you a taste of the Serverless VPC Access API C++ client library API.

All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock [`vpcaccess_v1::VpcAccessServiceClient`](/cpp/docs/reference/vpcaccess/2.31.0/classgoogle_1_1cloud_1_1vpcaccess__v1_1_1VpcAccessServiceClient) when testing your application.\n\n### More Information\n\n- [Error Handling](https://cloud.google.com/cpp/docs/reference/common/latest/common-error-handling.html) - describes how the library reports errors.\n- [How to Override the Default Endpoint](/cpp/docs/reference/vpcaccess/2.31.0/vpcaccess-override-endpoint) - describes how to override the default endpoint.\n- [How to Override the Authentication Credentials](/cpp/docs/reference/vpcaccess/2.31.0/vpcaccess-override-authentication) - describes how to change the authentication credentials used by the library.\n- [Override Retry, Backoff, and Idempotency Policies](/cpp/docs/reference/vpcaccess/2.31.0/vpcaccess-override-retry) - describes how to change the default retry policies.\n- [Environment Variables](/cpp/docs/reference/vpcaccess/2.31.0/vpcaccess-env) - describes environment variables that can configure the behavior of the library."]]
