This project follows the AMQP 0.9.1 specifications, targetting especially RabbitMQ.

Example

Note: To use async/await, enable the futures feature in your Cargo.toml.

```rust use lapin::{ message::DeliveryResult, options::*, types::FieldTable, BasicProperties, Channel, Connection, ConnectionProperties, ConsumerDelegate, }; use log::info;

[derive(Clone, Debug)]

struct Subscriber { channel: Channel, }

impl ConsumerDelegate for Subscriber { fn onnewdelivery(&self, delivery: DeliveryResult) { if let Ok(Some(delivery)) = delivery { self.channel .basicack(delivery.deliverytag, BasicAckOptions::default()) .wait() .expect("basic_ack"); } } }

fn main() { env_logger::init();

let addr = std::env::var("AMQP_ADDR").unwrap_or_else(|_| "amqp://127.0.0.1:5672/%2f".into());
let conn = Connection::connect(&addr, ConnectionProperties::default())
    .wait()
    .expect("connection error");

info!("CONNECTED");

let channel_a = conn.create_channel().wait().expect("create_channel");
let channel_b = conn.create_channel().wait().expect("create_channel");

channel_a
    .queue_declare(
        "hello",
        QueueDeclareOptions::default(),
        FieldTable::default(),
    )
    .wait()
    .expect("queue_declare");
let queue = channel_b
    .queue_declare(
        "hello",
        QueueDeclareOptions::default(),
        FieldTable::default(),
    )
    .wait()
    .expect("queue_declare");

info!("will consume");
channel_b
    .clone()
    .basic_consume(
        &queue,
        "my_consumer",
        BasicConsumeOptions::default(),
        FieldTable::default(),
    )
    .wait()
    .expect("basic_consume")
    .set_delegate(Box::new(Subscriber { channel: channel_b }));

let payload = b"Hello world!";

loop {
    channel_a
        .basic_publish(
            "",
            "hello",
            BasicPublishOptions::default(),
            payload.to_vec(),
            BasicProperties::default(),
        )
        .wait()
        .expect("basic_publish");
}

} ```
