Hi all,

I just published a Rust crate called rust-order-book, which is a port of one of my Node.js projects nodejs-order-book. I built it mainly to learn Rust while implementing a real-world trading engine.

The crate provides a high-performance limit order book with market and limit orders, price-time priority, order modification/cancellation, journaling, and snapshot/replay support. Some features like conditional orders are not yet ported, but will be added over time.

I’d love to get your feedback on:

• API design
• Code structure and idiomatic Rust usage
• Performance considerations
• Anything that could be improved

Thanks in advance!
