This method may only be called once. (i.e. it is not idempotent). N)r%startr&rrrr5sz Server.startgracecs|j|IdHdS)aStops this Server. This method immediately stops the server from servicing new RPCs in all cases. If a grace period is specified, this method waits until all active RPCs are finished or until the grace period is reached. RPCs that haven't been terminated within the grace period are aborted. If a grace period is not specified (by passing None for grace), all existing RPCs are aborted immediately and this method blocks until the last RPC handler terminates. This method is idempotent and may be called at any time. Passing a smaller grace value in a subsequent call will have the effect of stopping the Server sooner (passing None will have the effect of stopping the server immediately). Passing a larger grace value in a subsequent call will not have the effect of stopping the server later (i.e. the most restrictive grace value is used). Args: grace: A duration of time in seconds or None. N)r%shutdown)r&r7rrrstopsz Server.stoptimeoutcs|j|IdHS)aBlock current coroutine until the server stops. This is an EXPERIMENTAL API. The wait will not consume computational resources during blocking, and it will block until one of the two following conditions are met: 1) The server is stopped or terminated; 2) A timeout occurs if timeout is not `None`. The timeout argument works in the same way as `threading.Event.wait()`. https://docs.python.org/3/library/threading.html#threading.Event.wait Args: timeout: A floating point number specifying a timeout for the operation in seconds. Returns: A bool indicates if the operation times out. N)r%wait_for_termination)r&r:rrrr;szServer.wait_for_terminationcCs6t|dr|jrt|jd|jdSdSdS)zSchedules a graceful shutdown in current event loop.

Args: migration_thread_pool: A futures.ThreadPoolExecutor to be used by the Server to execute non-AsyncIO RPC handlers for migration purpose. handlers: An optional list of GenericRpcHandlers used for executing RPCs. More handlers may be added by calling add_generic_rpc_handlers any time before the server is started. interceptors: An optional list of ServerInterceptor objects that observe and optionally manipulate the incoming RPCs before handing them over to handlers. The interceptors are given control in the order they are specified. This is an EXPERIMENTAL API. options: An optional list of key-value pairs (:term:`channel_arguments` in gRPC runtime) to configure the channel. maximum_concurrent_rpcs: The maximum number of concurrent RPCs this server will service before returning RESOURCE_EXHAUSTED status, or None to indicate no limit. compression: An element of grpc.compression, e.g. grpc.compression.Gzip. This compression algorithm will be used for the lifetime of the server unless overridden by set_compression. Returns: A Server object.
