Implementations§

Source§

impl<Worker, C, R> ClusterClient<Partitioned<LocalClient<C, R, Worker::Activatable>, C, R>, Worker, C, R>
where C: Send + 'static, R: Send + 'static, (C, R): Partitionable<C, R>, Worker: AsRunnableWorker<C, R> + Clone + Send + Sync + 'static,

Source

fn new( timely_container: TimelyContainerRef<C, R, Worker::Activatable>, persist_clients: Arc<PersistClientCache>, txns_ctx: TxnsContext, tokio_handle: Handle, tracing_handle: Arc<TracingHandle>, worker_config: Worker, ) -> Self

Source

async fn build_timely( user_worker_config: Worker, config: TimelyConfig, epoch: ClusterStartupEpoch, persist_clients: Arc<PersistClientCache>, txns_ctx: TxnsContext, tracing_handle: Arc<TracingHandle>, tokio_executor: Handle, ) -> Result<TimelyContainer<C, R, Worker::Activatable>, Error>

Source

async fn build( &mut self, config: TimelyConfig, epoch: ClusterStartupEpoch, ) -> Result<(), Error>

Trait Implementations§

Source§

impl<Client: Debug, Worker: AsRunnableWorker<C, R>, C, R> Debug for ClusterClient<Client, Worker, C, R>

impl<Worker, C, R> GenericClient<C, R> for ClusterClient<Partitioned<LocalClient<C, R, Worker::Activatable>, C, R>, Worker, C, R>
where C: Send + Debug + TryIntoTimelyConfig + 'static, R: Send + Debug + 'static, (C, R): Partitionable<C, R>, Worker: AsRunnableWorker<C, R> + Send + Sync + Clone + 'static, Worker::Activatable: Send + Sync + 'static + Debug,

Source§

fn recv<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Option<R>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

§Cancel safety

This method is cancel safe. If recv is used as the event in a tokio::select! statement and some other branch completes first, it is guaranteed that no messages were received by this client.

Source§

fn send<'life0, 'async_trait>( &'life0 mut self, cmd: C, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Source§

fn as_stream<'a>( &'a mut self, ) -> Pin<Box<dyn Stream<Item = Result<R, Error>> + Send + 'a>>
