Crate ironsbe 

IronSBE

High-performance SBE (Simple Binary Encoding) server/client for Rust.

IronSBE provides a complete implementation of the FIX Simple Binary Encoding protocol optimized for low-latency financial systems.

Features

• Zero-copy encoding/decoding - Direct buffer access for minimal overhead
• Schema-driven code generation - Generate Rust code from FIX SBE XML schemas
• Sub-microsecond latency - Optimized for high-frequency trading
• Flexible transport - TCP, UDP multicast, and shared memory IPC
• Market data patterns - Order book management, gap recovery, A/B arbitration

Quick Start

use ironsbe::prelude::*;

// Create a server
let (mut server, handle) = ServerBuilder::new()
    .bind("0.0.0.0:9000".parse().unwrap())
    .handler(MyHandler)
    .build();

// Run the server
server.run().await?;
