Struct tokio_zmq::async_types::sink::MultipartSink

pub struct MultipartSink { /* private fields */ }

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

extern crate zmq;
extern crate futures;
extern crate tokio;
extern crate tokio_zmq;

use std::sync::Arc;

use futures::{Future, Sink};
use tokio_zmq::{prelude::*, Error, Multipart, Pub, Socket};

fn get_sink(socket: Socket) -> impl Sink<SinkItem = Multipart, SinkError = Error> {
    socket.sink(25)
}

fn main() {
    let context = Arc::new(zmq::Context::new());
    let socket = Pub::builder(context)
        .bind("tcp://*:5568")
        .build()
        .unwrap()
        .socket();
    let sink = get_sink(socket);

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

    // tokio::run(sink.send(msg.into())).unwrap();
}

Implementations

Trait Implementations

impl Sink for MultipartSink

type SinkItem = Multipart

The type of value that the sink accepts.

type SinkError = Error

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

fn start_send(
    &mut self,
    multipart: Self::SinkItem
) -> Result<AsyncSink<Self::SinkItem>, Self::SinkError>

Begin the process of sending a value to the sink.

fn poll_complete(&mut self) -> Result<Async<()>, 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>where
    Self: Sized,

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>,
    Self: Sized,

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>,
    Self: Sized,

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,
    Self: Sized,

Transforms the error returned by the sink.

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

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>where
    Self: Sized,

Adds a fixed-size buffer to the current sink.

fn flush(self) -> Flush<Self>where
    Self: Sized,

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

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

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>,
    Self: Sized,

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