RustMQ is the MQTT client written on pure Rust.

RustMQ

This repository is the bundle of crates devoted to the MQTT protocol.

Crates

• mqtt3 - MQTT protocol reader/writer
• netopt - TCP/SSL connection
• mqttc - Rust MQTT client

Binaries

• mqttc - Console MQTT client

Client

The client has the following functionality:

• QoS 0, QoS 1, QoS 2 publish/subscribe
• Last Will message
• Auto-Ping
• Auto-Reconnect
• SSL supported (include TLS v1.1, TLS v1.2)
• Modular: mqtt3, netopt
• Logging

Connect

let netopt = NetworkOptions::new();
let mut opts = ClientOptions::new();
opts.set_reconnect(ReconnectMethod::ReconnectAfter(Duration::from_secs(1)));
let mut client = opts.connect("127.0.0.1:1883", netopt).expect("Can't connect to server");

Publish

client.publish("a/b/c", "hello", PubOpt.at_least_once()).unwrap();
while (client.await().unwrap().is_some()) {};

Subscribe

client.subscribe("a/b/c").unwrap();
loop {
    match client.await().unwrap() {
        Some(message) => {
            println!("{:?}", message);
        },
        None => {}
    }
}
