Service Usage API C++ Client Library

An idiomatic C++ client library for the Service Usage API , an infrastructure service of Google Cloud that lets you list and manage APIs and Services in your Cloud projects.

While this library is GA, please note Google Cloud C++ client libraries do notfollow Semantic Versioning .

Quickstart

The following shows the code that you'll run in the google/cloud/serviceusage/quickstart/ directory, which should give you a taste of the Service Usage API C++ client library API.

 #include "google/cloud/serviceusage/v1/service_usage_client.h"
#include "google/cloud/project.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 2) {
    std::cerr << "Usage: " << argv[0] << " project-id\n";
    return 1;
  }

  namespace serviceusage = ::google::cloud::serviceusage_v1;
  auto client = serviceusage::ServiceUsageClient(
      serviceusage::MakeServiceUsageConnection());

  auto const project = google::cloud::Project(argv[1]);
  google::api::serviceusage::v1::ListServicesRequest request;
  request.set_parent(project.FullName());
  request.set_filter("state:ENABLED");
  for (auto s : client.ListServices(request)) {
    if (!s) throw std::move(s).status();
    std::cout << s->DebugString() << "\n";
  }

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
} 

Main classes

The main class in this library is serviceusage_v1::ServiceUsageClient . All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock serviceusage_v1::ServiceUsageClient when testing your application.
