Struct tokio_zmq::async::sink::MultipartSink

pub struct MultipartSink<E> where
    E: From<Error>,  { /* fields omitted */ }

The MultipartSink Sink handles sending streams of data to ZeroMQ Sockets.

You shouldn't ever need to manually create one. Here's how to get one from a 'raw' Socket' type.

Example

#![feature(conservative_impl_trait)]

extern crate zmq;
extern crate futures;
extern crate tokio_core;
extern crate tokio_zmq;

use std::rc::Rc;
use std::collections::VecDeque;

use futures::{Future, Sink};
use tokio_core::reactor::Core;
use tokio_zmq::async::{Multipart, MultipartStream};
use tokio_zmq::{Error, Socket};

fn get_sink(socket: Socket) -> impl Sink<SinkItem = Multipart, SinkError = Error> {
    socket.sink()
}

fn main() {
    let mut core = Core::new().unwrap();
    let context = Rc::new(zmq::Context::new());
    let socket = Socket::new(context, core.handle())
        .bind("tcp://*:5568")
        .build(zmq::PUB)
        .unwrap();
    let sink = get_sink(socket);

    let msg = zmq::Message::from_slice(b"Some message").unwrap();

    let mut multipart = VecDeque::new();
    multipart.push_back(msg);

    core.run(sink.send(multipart)).unwrap();
}

fn new(sock: Rc<Socket>, file: Rc<PollEvented<File<ZmqFile>>>) -> Self

Trait Implementations

impl<E> Sink for MultipartSink<E> where
    E: From<Error>, 

type SinkItem = Multipart

The type of value that the sink accepts.

type SinkError = E

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

fn start_send(
    &mut self,
    multipart: 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>

Flush all output from this sink, if necessary.

fn close(&mut self) -> Result<Async<()>, Self::SinkError>

A method to indicate that no more values will ever be pushed into this sink.

fn wait(self) -> Wait<Self>

Creates a new object which will produce a synchronous sink.

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

Composes a function in front of the sink.

fn with_flat_map<U, F, St>(self, f: F) -> WithFlatMap<Self, U, F, St> where
    F: FnMut(U) -> St,
    St: Stream<Item = Self::SinkItem, Error = Self::SinkError>, 

Composes a function in front of the sink.

fn sink_map_err<F, E>(self, f: F) -> SinkMapErr<Self, F> where
    F: FnOnce(Self::SinkError) -> E, 

Transforms the error returned by the sink.

fn sink_from_err<E>(self) -> SinkFromErr<Self, E> where
    E: From<Self::SinkError>, 

Map this sink's error to any error implementing From for this sink's Error, returning a new 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 as Stream>::Error>, 

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