Trait SinkSocket

pub trait SinkSocket: IntoInnerSocket {
    // Provided methods
    fn send(
        self,
        multipart: Multipart,
    ) -> <<Self as IntoInnerSocket>::Socket as InnerSocket<Self>>::Request { ... }
    fn sink(
        self,
        buffer_size: usize,
    ) -> <<Self as IntoInnerSocket>::Socket as InnerSocket<Self>>::Sink { ... }
}

This trait provides the basic Sink support for ZeroMQ Sockets. It depends on IntoInnerSocket and provides the send and sink methods.

Provided Methods

fn send( self, multipart: Multipart, ) -> <<Self as IntoInnerSocket>::Socket as InnerSocket<Self>>::Request

Send a single multipart message to the socket.

Example, using a Pub wrapper type

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

use std::sync::Arc;

use futures::Future;
use tokio_zmq::{prelude::*, async_types::MultipartStream, Error, Pub};

fn main() {
    let context = Arc::new(zmq::Context::new());
    let msg = zmq::Message::from_slice(b"Hello");
    let fut = Pub::builder(context)
        .connect("tcp://localhost:5569")
        .build()
        .and_then(|zpub| zpub.send(msg.into()));

    // tokio::run(fut.map(|_| ()).or_else(|e| {
    //     println!("Error: {}", e);
    //     Ok(())
    // }));
}

fn sink( self, buffer_size: usize, ) -> <<Self as IntoInnerSocket>::Socket as InnerSocket<Self>>::Sink

Send a stream of multipart messages to the socket.

It takes a buffer_size argument, which will determine how many Multiparts can be submitted into the send queue before the sink applies backpressure.

Example, using a Pub wrapper type

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

use std::sync::Arc;

use futures::{Future, Stream, stream::iter_ok};
use tokio_zmq::{prelude::*, async_types::MultipartStream, Error, Multipart, Pub};

fn main() {
    let context = Arc::new(zmq::Context::new());
    let fut = Pub::builder(context)
        .connect("tcp://localhost:5570")
        .build()
        .and_then(|zpub| {
            iter_ok(0..5)
                .map(|i| {
                    zmq::Message::from_slice(format!("i: {}", i).as_bytes()).into()
                })
                .forward(zpub.sink(25))
        });

    // tokio::run(fut.map(|_| ()).or_else(|e| {
    //     println!("Error: {}", e);
    //     Ok(())
    // }));
}

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
