An idiomatic C++ client library for Cloud Tasks API, a service that manages the execution of large numbers of distributed requests.
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/tasks/quickstart/ directory, which should give you a taste of the Cloud Tasks API C++ client library API.
The main class in this library is tasks_v2::CloudTasksClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock tasks_v2::CloudTasksClient when testing your application.
