PubNub Rust SDK

Build Status unsafe forbidden

The PubNub Rust SDK is based on Tokio 1.0. This library uses HTTP/2 to communicate with the PubNub Edge Messaging Network.

MSRV

Supports Rust 1.49.0 and higher.

Get Started

First you'll need to add the dependency to your project.

Cargo.toml

Easily add PubNub lib to your Cargo.toml file.

[dependencies.pubnub_hyper]
git = "https://github.com/pubnub/rust"

Simple Usage

Try the following sample code to get up and running quickly.

use futures_util::stream::StreamExt;
use pubnub_hyper::runtime::tokio_global::TokioGlobal;
use pubnub_hyper::transport::hyper::Hyper;
use pubnub_hyper::{core::json::object, Builder};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let transport = Hyper::new()
        .publish_key("demo")
        .subscribe_key("demo")
        .build()?;

    let mut pubnub = Builder::new()
        .transport(transport)
        .runtime(TokioGlobal)
        .build();

    let message = object! {
        "username" => "JoeBob",
        "content" => "Hello, world!",
    };

    let mut stream = pubnub.subscribe("my-channel").await;
    let timetoken = pubnub.publish("my-channel", message).await?;
    println!("timetoken = {:?}", timetoken);

    let received = stream.next().await;
    println!("received = {:?}", received);

    Ok(())
}
