1//! # RustKernel Order Matching
2//!
3//! GPU-accelerated order book matching for HFT.
4//!
5//! ## Kernels
6//! - `OrderMatchingEngine` - Price-time priority matching (<10μs P99)
7//!
8//! ## Features
9//! - Price-time priority matching
10//! - Support for limit and market orders
11//! - Self-trade prevention
12//! - Order book management with L2 snapshots
13//! - Batch order processing
