Ethereum: How to Create Interoperability between Different Future Traits in Rust
As you’re building concurrent orders for Binance using the binance_async library, you might encounter issues with interopability between different Ethereum traits. In this article, we’ll explore how to create interoperability between various future traits in Rust.
Understanding Interopability
Interoperability refers to the ability of different systems or components to communicate and exchange data seamlessly. In the context of Ethereum, it means that your Rust application can interact with Binance’s API without having to know the intricacies of their specific implementation.
Building Interop between Traits
To achieve interoperability between different traits in Rust, you’ll need to:
- Choose a common base trait: Select one of the existing traits (e.g.,
Order,MarketOrder, etc.) that your application can use as a foundation.
- Implement the necessary methods: Ensure that your chosen trait implements all the required methods for each specific data structure or functionality on Binance (e.g.,
BinanceOrder,BinanceMarketOrder, etc.).
- Create an adapter: Use an adapter library like
binance-asyncto create a new implementation of the common base trait that can be used across different traits.
- Use the adapter with your chosen trait: Replace the original trait in your application with the newly created adapter-based implementation.
Example: Creating Interop between Different Future Traits
Let’s say you have two Ethereum traits, Order and MarketOrder, which are both used for trading. You want to make concurrent orders using both traits on Binance.
First, let’s assume that the binance-async library provides an implementation of the Order trait (BinancesOrder), while a separate implementation is provided for MarketOrder (BinanceMarketOrder).
// binance-async library providing Order trait (e.g., BinancesOrder)
use binance_async::{Order, BinanceOrder};
struct MyOrder {
// ...
}
impl Order for MyOrder {}
// Implement the necessary methods for BinanceOrder
// Create an adapter to convert BinancesOrder to BinanceMarketOrder
enum MarketOrderAdapter {
Binance(BinanceOrder),
}
impl Adapter for MarketOrderAdapter {
type Output = BinanceMarketOrder;
fn adapt(&self, binance_order: &BinancesOrder) -> Self::Output {
// Replace the original Binance order with a new instance of BinancesOrder
let binance_market_order = match self {
MarketOrderAdapter::Binance(binance_order) => binateas(MarketOrder::from(*binance_order)),
_ => unreachable!(),
};
// Implement any necessary methods for BinanceMarketOrder here
binance_market_order.clone()
}
}
In this example, we’ve created a MarketOrderAdapter that can convert between the two traits. We then use this adapter to create an instance of BinanceMarketOrder from a BinancesOrder. The rest is straightforward: you’ll need to implement any additional methods required for BinanceMarketOrder.
Conclusion
By following these steps, you should be able to create interoperability between different future traits in Rust. Remember to choose a common base trait, implement the necessary methods, and use an adapter library like binance-async to bridge the gap.
As an aside, keep in mind that this is just one possible approach to solving this problem. Depending on your specific requirements and constraints, you may need to experiment with different adaptations or use cases for Binance’s API.
Notes
- Make sure to check the documentation for
binance-asynclibrary and its respective implementation of each trait.
