Struct ClusterClient

pub struct ClusterClient<C>
where
    C: ClusterSpec,
    (C::Command, C::Response): Partitionable<C::Command, C::Response>,
{
    inner: Option<Partitioned<LocalClient<C::Command, C::Response>, C::Command, C::Response>>,
    timely_container: Arc<Mutex<Option<TimelyContainer<C>>>>,
    tokio_handle: Handle,
    cluster_spec: C,
}

A client managing access to the local portion of a Timely cluster

Fields

inner: Option<Partitioned<LocalClient<C::Command, C::Response>, C::Command, C::Response>>

The actual client to talk to the cluster

timely_container: Arc<Mutex<Option<TimelyContainer<C>>>>

The running timely instance

tokio_handle: Handle

The handle to the Tokio runtime.

cluster_spec: C

Implementations

impl<C> ClusterClient<C>

where C: ClusterSpec, (C::Command, C::Response): Partitionable<C::Command, C::Response>,

pub fn new( timely_container: Arc<Mutex<Option<TimelyContainer<C>>>>, tokio_handle: Handle, cluster_spec: C, ) -> Self

Create a new ClusterClient.

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

Trait Implementations

impl<C> Debug for ClusterClient<C>

where C: ClusterSpec, (C::Command, C::Response): Partitionable<C::Command, C::Response>,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<C> GenericClient<<C as ClusterSpec>::Command, <C as ClusterSpec>::Response> for ClusterClient<C>

where C: ClusterSpec, (C::Command, C::Response): Partitionable<C::Command, C::Response>,

fn recv<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Option<C::Response>, 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.

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

where Self: 'async_trait, 'life0: 'async_trait,

Sends a command to the dataflow server.

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

where R: Send + 'a,

Returns an adapter that treats the client as a stream.
