Cloud TPU API C++ Client Library

An idiomatic C++ client library for Cloud TPU, a service that provides customers with access to Google TPU technology.

While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

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

#include "google/cloud/tpu/v2/tpu_client.h"
#include <iostream>

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

  namespace tpu = ::google::cloud::tpu_v2;
  auto client = tpu::TpuClient(tpu::MakeTpuConnection());

  auto const parent = std::string{"projects/"} + argv[1] + "/locations/-";
  for (auto n : client.ListNodes(parent)) {
    if (!n) throw std::move(n).status();
    std::cout << n->DebugString() << "\n";
  }

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

Main classes

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.
