An idiomatic C++ client library for Cloud Billing API, a service that interacts with billing accounts, billing budgets, and billing catalogs.
While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.
Quickstart
The following shows the code that you'll run in the google/cloud/billing/quickstart/ directory, which should give you a taste of the Cloud Billing Budget API C++ client library API.
This library offers multiple *Client classes, which are listed below. Each one of these classes exposes all the RPCs for a service as member functions of the class. This library groups multiple services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.
The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the *Client classes when testing your application.
