Hi, is there any plan to upgrade to tokio 1.0?

For integration tests have a NATS_BIN environment variable and automatically start the nats server when the tests run. Opposed to requiring the nats server be running for the tests to work.

Address should allow specifying strings as well as IP addresses. It should allow any address type tokio accepts

Hello,

I have run into an issue connecting to the official NATS server (gnatsd).

Each connection attempt fails with following message:

Received invalid server message, err: invalid control line "INFO {\"server_id\":\"EIcTs1hcrlywWCrsUATcqP\",\"version\":\"1.1.0\",\"git_commit\":\"add6d79\",\"go\":\"go1.9.4\",\"host\":\"0.0.0.0\",\"port\":4222,\"auth_required\":false,\"tls_required\":false,\"tls_verify\":false,\"max_payload\":1048576} \r\n"

The server version is quite old now, so it might be a gnatsd bug.

Hi,
we are working on a PoC Rust application that uses rants to connect to a Nats Streaming server.
Everything works as expected, anyway, we could not figure out how to perform a durable subscription.
Is a code example available somewhere?

I want to construct subjects programmatically by selecting branches from a subject tree for a given NATS server. I see that Subject's internal representation uses Vec and a flag for wildcards and for a subject hierarchy already represented as a tree of structs in Rust it would make more sense to construct this Vec directly.

This requires async drop

Hey, i have some issue while making an infinite subscriber.
Here is the code:

let addr = std::env::var("NATS_ADDR").unwrap_or_else(|_| "127.0.0.1:4222".into());
let nats_client = Client::new(vec![addr.parse().unwrap()]);
nats_client.connect().await;

let subject = "test".parse().unwrap()
let (_, mut subscription) = nats_client.subscribe(&subject, 1024).await.unwrap();

loop {
        let message = subscription.next().await.unwrap();
        let message = String::from_utf8(message.into_payload()).unwrap();
        info!("Nats message received {}", message);
}

It works but I can't exit the program :/ (no SIGINT catch ?)
I think having an example of this use case should be useful.

How can I set the timeout of a request?
This simple test hangs forever at the client.request(...) line because nobody replies to the request; anyway, I would like it to fail after some time:

#[tokio::test]
async fn response_should_timeout() {
    let subject = "test_subject".parse().unwrap();

    let client = rants::Client::new(vec!["127.0.0.1:4222".parse().unwrap()]);
    client.connect().await;

    client.publish(&subject, b"").await.unwrap();
    println!("Publish -> ok");

    client.request(&subject, b"").await.unwrap();
    println!("Request -> ok");  // <-- this is never printed
}

pub async fn connect(&self) 

I tried to use task::block_on (async-std) for above connect function it crashed

I noticed that I can't retrieve the name of a Subject. If I subscribe to a wildcard/prefix subject such as notifications.>, I want to be able to inspect which subject I received (e.g. notifications.emergency.accident, and react to it accordingly.

It looks like the only thing I can do is use Display.
