            # Configuration class for the Operations API.
            #
            # This class represents the configuration for Operations,
            # providing control over timeouts, retry behavior, logging, transport
            # parameters, and other low-level controls. Certain parameters can also be
            # applied individually to specific RPCs. See
            # {::Google::Longrunning::Operations::Client::Configuration::Rpcs}
            # for a list of RPCs that can be configured independently.
            #
            # Configuration can be applied globally to all clients, or to a single client
            # on construction.
            #
            # # Examples
            #
            # To modify the global config, setting the timeout for list_operations
            # to 20 seconds, and all remaining timeouts to 10 seconds:
            #
            #     ::Google::Longrunning::Operations::Client.configure do |config|
            #       config.timeout = 10.0
            #       config.rpcs.list_operations.timeout = 20.0
            #     end
            #
            # To apply the above configuration only to a new client:
            #
            #     client = ::Google::Longrunning::Operations::Client.new do |config|
            #       config.timeout = 10.0
            #       config.rpcs.list_operations.timeout = 20.0
