A MQTT client based on actix framework

The actix-mqtt-client crate is a mqtt client based on the actix framework

Basic usage and example

First, create 2 actix actors, one for receiving publish messages, the other one for receiving error messages from the client: ```rust pub struct ErrorActor;

impl actix::Actor for ErrorActor { type Context = actix::Context; }

impl actix::Handler for ErrorActor { type Result = (); fn handle(&mut self, error: ErrorMessage, _: &mut Self::Context) -> Self::Result { log::error!("{}", error.0); } }

pub struct MessageActor;

impl actix::Actor for MessageActor { type Context = actix::Context; }

impl actix::Handler for MessageActor { type Result = (); fn handle( &mut self, msg: PublishMessage, : &mut Self::Context, ) -> Self::Result { log::info!( "Got message: id:{}, topic: {}, payload: {:?}", msg.id, msg.topicname, msg.payload ); } } ```

Then, connect to the server(using tokio) and use the read and write part of the stream along with the actors to create a MqttClient: rust System::run(|| { let socket_addr = SocketAddr::from_str("127.0.0.1:1883").unwrap(); Arbiter::spawn( TcpStream::connect(&socket_addr) .and_then(|stream| { let (r, w) = stream.split(); let mut client = MqttClient::new( r, w, String::from("mqtt_client"), MqttOptions::default(), MessageActor.start().recipient(), ErrorActor.start().recipient(), ); log::info!("Connect"); client.connect().map(|_| client) }) .and_then(|client| { log::info!("Subscribe"); client .subscribe(String::from("topic"), mqtt::QualityOfService::Level2) .map(|_| client) }) .and_then(|client| { log::info!("Publish Level0"); client .publish( String::from("topic"), mqtt::QualityOfService::Level0, Vec::from("level0".as_bytes()), ) .map(|_| client) }) .and_then(|client| { log::info!("Publish Level1"); client .publish( String::from("topic"), mqtt::QualityOfService::Level1, Vec::from("level1".as_bytes()), ) .map(|_| client) }) .and_then(|client| { log::info!("Publish Level2"); client .publish( String::from("topic"), mqtt::QualityOfService::Level2, Vec::from("level2".as_bytes()), ) .map(|_| client) }) .and_then(|client| { log::info!("Disconnect"); client.disconnect() }) .map_err(|_| ()), ); }) .unwrap();
