IronFix

A high-performance FIX/FAST protocol engine for Rust.

IronFix provides a complete implementation of the FIX protocol with support for all versions from FIX 4.0 through FIX 5.0 SP2, as well as FAST-encoded market data.

Features

• Zero-copy parsing: Field values reference the original buffer
• SIMD-accelerated: Uses memchr for fast delimiter search
• Type-safe: Compile-time checked session states and message types
• Async support: Built on Tokio for high-performance networking
• Flexible: Supports both sync and async operation modes

Quick Start

use ironfix_example::prelude::*;

// Create an engine with your application handler
let engine = EngineBuilder::new()
    .with_application(MyApplication)
    .add_session(SessionConfig::new(
        CompId::new("SENDER").unwrap(),
        CompId::new("TARGET").unwrap(),
        "FIX.4.4",
    ))
    .build();
