ERROR HANDLING

Provides more detailed error information

You can check out the Binance Error Codes

use binance::errors::ErrorKind as BinanceLibErrorKind;

[...]

Err(err) => {
    println!("Can't put an order!");

    match err.0 {
        BinanceLibErrorKind::BinanceError(response) => match response.code {
            -1013_i16 => println!("Filter failure: LOT_SIZE!"),
            -2010_i16 => println!("Funds insufficient! {}", response.msg),
            _ => println!("Non-catched code {}: {}", response.code, response.msg),
        },
        BinanceLibErrorKind::Msg(msg) => {
            println!("Binancelib error msg: {}", msg)
        }
        _ => println!("Other errors: {}.", err.0),
    };
}

TESTNET AND API CLUSTERS

You can overwrite the default binance api urls if there are performance issues with the endpoints.

You can check out the Binance API Clusters.

The same is applicable for Testnet and Binance.US support. See example below:

let general: General = if use_testnet {
    let config = Config::default().set_rest_api_endpoint("https://testnet.binance.vision");
                                  // .set_ws_endpoint("wss://testnet.binance.vision/ws")
                                  // .set_futures_rest_api_endpoint("https://testnet.binancefuture.com/api")
                                  // .set_futures_ws_endpoint("https://testnet.binancefuture.com/ws")
    Binance::new_with_config(None, None, &config)
} else {
    Binance::new(None, None)
};
