rust-bybit

English | 简体中文

Unofficial Rust API connector for Bybit's WebSockets V5 APIs.

Disclaimer

This is an unofficial Rust API connector for Bybit's APIs and the user assumes all responsibility and risk for the use of this project.

Installation

Add this to Cargo.toml

[dependencies]
rust-bybit = "0.2"

Basic Usage

Create a WebSocket client for specific channel:

use bybit::ws::response::SpotPublicResponse;
use bybit::ws::spot;
use bybit::KlineInterval;
use bybit::WebSocketApiClient;

let mut client = WebSocketApiClient::spot().build();

Subscribe to topics you are interested in. The following code will subscribe to all topics with symbol=ETHUSDT, or symbol=BTC3SUSDT for leveraged token (for all available topics, please check Bybit V5 API). Note that the subscriptions will not be sent until client.run is called:

let symbol = "ETHUSDT";
let lt_symbol = "BTC3SUSDT";

client.subscribe_orderbook(symbol, spot::OrderbookDepth::Level1);
client.subscribe_orderbook(symbol, spot::OrderbookDepth::Level50);
client.subscribe_trade(symbol);
client.subscribe_ticker(symbol);
client.subscribe_kline(symbol, KlineInterval::Min1);
client.subscribe_lt_kline(lt_symbol, KlineInterval::Min5);
client.subscribe_lt_ticker(lt_symbol);
client.subscribe_lt_nav(lt_symbol);

Pass a callback function to client.run to start the client. The callback must accept exactly one parameter: the Enum which variants are WebSocket responses. The callback function will be called whenever a WebSocket response is received:

let callback = |res: SpotPublicResponse| match res {
    SpotPublicResponse::Orderbook(res) => println!("Orderbook: {:?}", res),
    SpotPublicResponse::Trade(res) => println!("Trade: {:?}", res),
    SpotPublicResponse::Ticker(res) => println!("Ticker: {:?}", res),
    SpotPublicResponse::Kline(res) => println!("Kline: {:?}", res),
    SpotPublicResponse::LtTicker(res) => println!("LtTicker: {:?}", res),
    SpotPublicResponse::LtNav(res) => println!("LtNav: {:?}", res),
    SpotPublicResponse::Op(res) => println!("Op: {:?}", res),
};

match client.run(callback) {
    Ok(_) => {}
    Err(e) => println!("{}", e),
}

This is a simple example that just print the received WebSocket responses. There are some more complex examples for real usage demonstration, such as maintaining a local order book. You can run cargo run --example local_orderbook to see how it works.
