Crate ccxt_core 

CCXT Core Library

This is the core library for CCXT Rust implementation, providing fundamental data structures, error types, and traits for cryptocurrency exchange integration.

Features

• Type Safety: Leverages Rust’s type system for compile-time guarantees
• Precision: Uses rust_decimal::Decimal for accurate financial calculations
• Async/Await: Built on tokio for high-performance async operations
• Error Handling: Comprehensive error types with thiserror

Example

use ccxt_core::prelude::*;

// Create a market
let market = Market::new_spot(
    "btc/usdt".to_string(),
    "BTC/USDT".to_string(),
    "BTC".to_string(),
    "USDT".to_string(),
);

// Create an order
let order = Order::new(
    "12345".to_string(),
    "BTC/USDT".to_string(),
    OrderType::Limit,
    OrderSide::Buy,
    rust_decimal_macros::dec!(0.1),
    Some(rust_decimal_macros::dec!(50000.0)),
    OrderStatus::Open,
);
