Struct BinanceApiError 

pub struct BinanceApiError {
    pub code: i32,
    pub msg: String,
}

Binance REST API error.

Represents errors returned by the Binance REST API in the format:

{"code": -1121, "msg": "Invalid symbol."}

This error type preserves the original Binance error code and message, and can be converted to the appropriate CoreError variant based on the error code.

Fields

code: i32

Binance error code (negative integer)

msg: String

Error message from Binance

Implementations

impl BinanceApiError

pub fn new(code: i32, msg: impl Into<String>) -> Self

Creates a new Binance API error.

Arguments

• code - The Binance error code (typically negative)
• msg - The error message from Binance

Example

use ccxt_exchanges::binance::error::BinanceApiError;

let err = BinanceApiError::new(-1121, "Invalid symbol.");
assert_eq!(err.code, -1121);

pub fn from_json(json: &Value) -> Option<Self>

Parses a Binance API error from JSON response.

Arguments

• json - The JSON response from Binance API

Returns

Returns Some(BinanceApiError) if the JSON contains code and msg fields, None otherwise.

Example

use ccxt_exchanges::binance::error::BinanceApiError;
use serde_json::json;

let response = json!({"code": -1121, "msg": "Invalid symbol."});
let err = BinanceApiError::from_json(&response);
assert!(err.is_some());
assert_eq!(err.unwrap().code, -1121);

pub fn is_rate_limit(&self) -> bool

Returns true if this is a rate limit error.

Rate limit errors have codes:

• -1003: Too many requests
• -1015: Too many orders

pub fn is_ip_banned(&self) -> bool

Returns true if this is an IP ban error.

IP ban errors have code -1003 with specific messages or HTTP 418 status.

pub fn is_auth_error(&self) -> bool

Returns true if this is an authentication error.

pub fn is_invalid_symbol(&self) -> bool

Returns true if this is an invalid symbol error.

pub fn is_insufficient_balance(&self) -> bool

Returns true if this is an insufficient balance error.

pub fn is_order_not_found(&self) -> bool

Returns true if this is an order not found error.

pub fn to_core_error(&self) -> CoreError

Converts this error to the appropriate CoreError variant.

The mapping follows these rules:

• Authentication errors (-2014, -2015, -1022) → CoreError::Authentication
• Rate limit errors (-1003, -1015) → CoreError::RateLimit
• Invalid symbol (-1121) → CoreError::BadSymbol
• Insufficient balance (-2010, -2011) → CoreError::InsufficientBalance
• Order not found (-2013) → CoreError::OrderNotFound
• Invalid order errors → CoreError::InvalidOrder
• Network errors (-1001) → CoreError::Network
• Other errors → CoreError::Exchange
