stomp-rs v0.9.0

stomp-rs provides a full STOMP 1.2 client implementation for the Rust programming language. This allows programs written in Rust to interact with message queueing services like ActiveMQ, RabbitMQ, HornetQ and OpenMQ.

• Connect
• Subscribe
• Send
• Acknowledge (Auto/Client/ClientIndividual)
• Transactions
• Receipts
• Disconnect
• Heartbeats

The APIs for stomp-rs are not yet stable and are likely to fluctuate before v1.0.

Examples

Connect / Subscribe / Send

extern crate stomp;
use stomp::frame::Frame;
use stomp::subscription::AckOrNack::Ack;

fn main() {
  
  let destination = "/topic/messages";
  let mut message_count: u64 = 0;

  let mut session = match stomp::session("127.0.0.1", 61613).start() {
      Ok(session) => session,
      Err(error)  => panic!("Could not connect to the server: {}", error)
   };
  
  session.subscription(destination, |frame: &Frame| {
    message_count += 1;
    println!("Received message #{}:\n{}", message_count, frame);
    Ack
  }).start();
  
  session.message(destination, "Animal").send();
  session.message(destination, "Vegetable").send();
  session.message(destination, "Mineral").send();
  
  session.listen(); // Loops infinitely, awaiting messages

  session.disconnect();
}

Session Configuration

use stomp::header::header::Header;
use stomp::connection::{HeartBeat, Credentials};
// ...
let mut session = match stomp::session("127.0.0.1", 61613)
  .with(Credentials("sullivan", "m1k4d0"))
  .with(HeartBeat(5000, 2000))
  .with(Header::new("custom-client-id", "hmspna4"))
  .start() {
      Ok(session) => session,
      Err(error)  => panic!("Could not connect to the server: {}", error)
   };

Message Configuration

use stomp::header::{Header, SuppressedHeader, ContentType};
// ...
session.message(destination, "Hypoteneuse".as_bytes())
  .with(ContentType("text/plain"))
  .with(Header::new("persistent", "true"))
  .with(SuppressedHeader("content-length")
  .send();

Subscription Configuration

use stomp::subscription::AckMode;
use stomp::header::Header;
use stomp::frame::Frame;
// ...
  let id = session.subscription(destination, |frame: &Frame| {
    message_count += 1;
    println!("Received message #{}:\n{}", message_count, frame);
    Ack
  })
  .with(AckMode::Client)
  .with(Header::new("custom-subscription-header", "lozenge"))
  .start();

Transactions

match session.begin_transaction() {
  Ok(mut transaction) => {
    transaction.message(destination, "Animal").send();
    transaction.message(destination, "Vegetable").send();
    transaction.message(destination, "Mineral").send();
    transaction.commit();
},
  Err(error)  => panic!("Could not connect to the server: {}", error)
};

Handling RECEIPT frames

If you include a ReceiptHandler in your message, the client will request that the server send a receipt when it has successfully processed the frame.

session.message(destination, "text/plain", "Hypoteneuse".as_bytes())
  .with(ReceiptHandler::new(|frame: &Frame| println!("Got a receipt for 'Hypoteneuse'.")))
  .send();

Handling ERROR frames

session.on_error(|frame: &Frame| {
  panic!("ERROR frame received:\n{}", frame);
});
