Common Components for the Google Cloud C++ Client Libraries

Overview

This library contains common components shared by all the Google Cloud C++ Client Libraries. Including:

• Credentials are used to configure authentication in the client libraries. See Authentication Components for more details on authentication.
• Options are used to override the client library default configuration. See Client Library Configuration for more details on library configuration.
• Status error codes and details from an operation.
• StatusOr returns a value on success and a Status on error.
• future and promise futures (a holder that will receive a value asynchronously) and promises (the counterpart of a future, where values are stored asynchronously). They satisfy the API for std::future and std::promise, and add support for callbacks and cancellation.

Warning: Some namespaces are reserved for implementation details and are subject to change without notice. Do not use any symbols in these namespaces as your application may break when trying to use future versions of the library. These namespaces include: - Any namespace with internal in its name, including google::cloud::internal and google::cloud::rest_internal. - Any namespace with testing in its name, including google::cloud::testing_util.
