An idiomatic C++ client library for theConnectors API, a service that enables users to create and manage connections to Google Cloud services and third-party business applications.
While this library isGA, please note that the Google Cloud C++ client libraries donotfollowSemantic Versioning.
Quickstart
The following shows the code that you'll run in thegoogle/cloud/connectors/quickstart/directory, which should give you a taste of the Connectors API C++ client library API.
The main class in this library isconnectors_v1::ConnectorsClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mockconnectors_v1::ConnectorsClientwhen testing your application.
Retry, Backoff, and Idempotency Policies.
The library automatically retries requests that fail with transient errors, and usesexponential backoffto backoff between retries. Application developers can override the default policies.
