Perp Order Book

Minimal single-market perpetual order book with deterministic matching and command-journal replay.

Prerequisites

• Rust toolchain (stable, with Cargo)

Quick Start

1. Build the project:

cargo build

2. Run the demo scenario (prints commands/events and final top of book):

cargo run

3. Run all tests:

cargo test

Benchmarking

Benchmarks use Criterion.

Run the benchmark suite:

cargo bench --bench engine

Optional faster local run (smaller sample size):

cargo bench --bench engine -- --sample-size 10

Results are printed in the terminal and written under target/criterion/.
