This is a minimal interface for the Kraken exchange Websockets API using the async-std runtime.

Prerequisites

To use the private connection you will need to generate an API-Key and an API-Secret to authenticate to the desired Kraken account.
How to generate an API key pair?

Usage

Automatically add to your Cargo.toml with shell cargo add async_kraken_ws or manually adding as dependecy in Cargo.toml: ```toml [dependencies]

..

asynckrakenws = "~0.1.0" ```

Example

```rust use asynckrakenws::client::KrakenWS;

fn getkeys() -> (String, String) { let content = std::fs::readto_string("key").expect("File not found"); let lines: Vec<&str> = content.lines().collect();

let key = String::from(lines[0]);
let secret = String::from(lines[1]);

(key, secret)

}

[async_std::main]

async fn main() { let (apikey, apisecret) = getkeys(); let kpr = KrakenWS::runprivate(|x| println!("{}", x.tostring()), apikey, apisecret).await; let _ = kpr.subscribeopenorders().await; let _ = kpr.subscribeown_trades().await;

let kpu = KrakenWS::run_public(|x| println!("{}", x.to_string())).await;
let _ = kpu.subscribe_ticker(vec!["XBT/EUR"]).await;
let _ = kpu.subscribe_ohlc(vec!["XBT/EUR"], 1).await;
let _ = kpu.subscribe_book(vec!["XBT/EUR"], 100).await;
let _ = kpu.subscribe_spread(vec!["XBT/EUR"]).await;
let _ = kpu.subscribe_trade(vec!["XBT/EUR"]).await;

loop {
    std::thread::sleep(std::time::Duration::from_secs(30));
    let _ = kpu.ping().await;
    let _ = kpr.ping().await;
}

}

```
