Struct tk_pool::uniform::UniformMx

pub struct UniformMx<S, E, A = Error> { /* fields omitted */ }

A simple uniform connection pool

This pool connects fixed number of connections to each IP/Port pair (if they are available) and distribute requests by round-robin

Note the pool has neither a buffer of it's own nor any internal tasks, so you are expected to use Sink::buffer and call poll_complete on every wake-up.

Methods

impl<S, E, A> UniformMx<S, E, A> where S: Sink<SinkError=E>, E: From<A> + Display

fn new<C>(handle: &Handle,
          config: &Arc<Config>,
          address: Box<Stream<Item=Address, Error=A>>,
          connect: C)
          -> UniformMx<S, E, A> where C: Connect<Sink=S, Error=E> + 'static

Create a connection pool

This doesn't establish any connections even in eager mode. You need to call poll_complete to start.

Trait Implementations

impl<S, E, A> Sink for UniformMx<S, E, A> where S: Sink<SinkError=E>, E: From<A> + Display

type SinkItem = S::SinkItem

The type of value that the sink accepts.

type SinkError = S::SinkError

The type of value produced by the sink when an error occurs.

fn start_send(&mut self,
              item: Self::SinkItem)
              -> StartSend<Self::SinkItem, Self::SinkError>

Begin the process of sending a value to the sink.

fn poll_complete(&mut self) -> Poll<(), Self::SinkError>

Make progress on all pending requests, and determine whether they have completed.

fn with<U, F, Fut>(self, f: F) -> With<Self, U, F, Fut> where F: FnMut(U) -> Fut,
        Fut: IntoFuture<Item=Self::SinkItem>,
        Fut::Error: From<Self::SinkError>

Composes a function in front of the sink.

fn buffer(self, amt: usize) -> Buffer<Self>

Adds a fixed-size buffer to the current sink.

fn flush(self) -> Flush<Self>

A future that completes when the sink has finished processing all pending requests.

fn send(self, item: Self::SinkItem) -> Send<Self>

A future that completes after the given item has been fully processed into the sink, including flushing.

fn send_all<S>(self, stream: S) -> SendAll<Self, S> where S: Stream<Item=Self::SinkItem>, Self::SinkError: From<S::Error>

A future that completes after the given stream has been fully processed into the sink, including flushing.
