Kraken WebSocket API Client

A strongly-typed Rust SDK for the Kraken WebSocket API.

This crate is an unofficial, community-driven effort.

Installation

[dependencies]
kraken_ws_client = "0.24"

Usage

use futures::StreamExt;
use kraken_ws_client::api::SubscribeTickerRequest;

#[tokio::main]
async fn main() {
    let mut client = kraken_ws_client::connect_public()
        .await
        .expect("cannot connect");

    client
        .send(SubscribeTickerRequest::symbol("BTC/USD"))
        .await
        .expect("cannot send request");

    while let Some(event) = client.ticker_events().next().await {
        dbg!(&event);
    }
}
use kraken_rest_client::Client as RestClient;

let api_key = std::env::var("KRAKEN_API_KEY").expect("api key not defined");
let api_secret = std::env::var("KRAKEN_API_SECRET").expect("api secret not defined");

let rest_client = RestClient::new(api_key, api_secret);
let resp = rest_client.get_web_sockets_token().send().await?;
let token = resp.token;

let mut ws_private_client = kraken_ws_client::connect_private(token)
    .await
    .expect("cannot connect");

ws_private_client
    .send(SubscribeExecutionsRequest::new())
    .await
    .expect("cannot send request");

while let Ok(msg) = ws_private_client.messages().recv().await {
    dbg!(msg);
}

or run the example:

cargo run --example ticker

Status
