A Pragmatic Guide to Introducing Rust into C/C++ Codebases with Minimal Risk

Step-by-step framework to adopt Rust in legacy C/C++ systems, reduce vulnerabilities by 60%, and accelerate development without rewrites.

About This Guide

Legacy C++ systems slow development, create vulnerabilities, and resist scaling. Complete rewrites cause downtime and drain resources. This practical guide presents tested strategies for incremental migration without system rewrites, developed through implementations with engineering teams across fintech, automotive, and technology sectors.

What’s inside

• 4-step migration framework from assessment to full adoption
• Real case study: 45% faster delivery, 60% fewer bugs
• Timeline guidance for each phase (2 weeks to 18 months)
• Common myths debunked about Rust adoption
• Incremental approach that maintains operational continuity

Who This Guide Helps

Engineering leaders, CTOs, and technical decision-makers at companies with established C++ codebases looking for a structured, low-risk path to modernization without disrupting current operations.
