Client library for Binance

tokio-binance

Unofficial async client for Binance.

Fork

This is the fork from the tokio-binance project, created in order to create missing api and to update dependencies.

Examples

Add this in your Cargo.toml:

[dependencies]
tokio-binance = "https://github.com/sgaliamov/tokio-binance"

Client

use tokio_binance::{AccountClient,  ID};
use serde_json::Value;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = AccountClient::connect("<api-key>", "<secret-key>", "<api-url>")?;
    let response = client
        .get_order("BNBUSDT", ID::ClientOId("<uuid>"))
        // optional: processing time for request; default is 5000, can't be above 60000.
        .with_recv_window(8000)
        .json::<Value>()
        .await?;
    Ok(())
}

Websocket

use tokio_binance::*;
use tokio::time::{delay_for, Duration};
use serde_json::Value;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = UserDataClient::connect("<api-key>", "<api-url>")?;
    let value = client.start_stream().json::<Value>().await?;

    let listen_key = value["listenKey"].as_str().unwrap();
    let listen_key_copy = listen_key.to_string();

    tokio::spawn(async move {
        loop {
            delay_for(Duration::from_secs(30*60)).await;
            if let Err(e) = client.keep_alive(&listen_key_copy).text().await {
                eprintln!("{}", e);
                return
            }
        }
    });

    let channel = Channel::UserData(listen_key);
    let mut stream = WebSocketStream::connect(channel, "<ws-url>").await?;

    while let Some(value) = stream.json::<Value>().await? {
        if channel == value["stream"] {
            println!("{}", serde_json::to_string_pretty(&value)?);
        }
    }
    Ok(())
}
