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

Feature switches

• native-tls (default): enable amqps support through native-tls
• openssl: enable amqps support through openssl (preferred over native-tls when set)
• rustls: enable amqps support through rustls (preferred over openssl when set, uses rustls-native-certs by default)
• rustls-native-certs: same as rustls, be ensure we'll still use rustls-native-certs even if the default for rustls changes
• rustls-webpki-roots-certs: same as rustls but using webkit-roots instead of rustls-native-certs

Example

```rust use futuresexecutor::LocalPool; use futuresutil::{future::FutureExt, stream::StreamExt, task::LocalSpawnExt}; use lapin::{ options::*, publisher_confirm::Confirmation, types::FieldTable, BasicProperties, Connection, ConnectionProperties, Result, }; use log::info;

fn main() -> Result<()> { env_logger::init();

let addr = std::env::var("AMQP_ADDR").unwrap_or_else(|_| "amqp://127.0.0.1:5672/%2f".into());
let mut executor = LocalPool::new();
let spawner = executor.spawner();

executor.run_until(async {
    let conn = Connection::connect(&addr, ConnectionProperties::default()).await?;

    info!("CONNECTED");

    let channel_a = conn.create_channel().await?;
    let channel_b = conn.create_channel().await?;

    let queue = channel_a
        .queue_declare(
            "hello",
            QueueDeclareOptions::default(),
            FieldTable::default(),
        )
        .await?;

    info!("Declared queue {:?}", queue);

    let consumer = channel_b
        .clone()
        .basic_consume(
            "hello",
            "my_consumer",
            BasicConsumeOptions::default(),
            FieldTable::default(),
        )
        .await?;
    let _consumer = spawner.spawn_local(async move {
        info!("will consume");
        consumer
            .for_each(move |delivery| {
                let delivery = delivery.expect("error caught in in consumer");
                channel_b
                    .basic_ack(delivery.delivery_tag, BasicAckOptions::default())
                    .map(|_| ())
            })
            .await
    });

    let payload = b"Hello world!";

    loop {
        let confirm = channel_a
            .basic_publish(
                "",
                "hello",
                BasicPublishOptions::default(),
                payload.to_vec(),
                BasicProperties::default(),
            )
            .await?
            .await?;
        assert_eq!(confirm, Confirmation::NotRequested);
    }
})

} ```
