Rust for C++ Developers. Modern Memory Safety Without Garbage Collection Overhead - James Neil

C++ developers already know the hard parts. Now write code the compiler proves safe.

Decades of systems programming have made one truth undeniable: writing fast software in C++ demands constant, exhausting vigilance. Every pointer dereference, every heap allocation, every thread interaction carries the risk of undefined behavior, data races, and security vulnerabilities that only appear at runtime, often in production.

Rust eliminates this tradeoff entirely.

Rust for C++ Developers is a technically rigorous, concept-mapping guide designed exclusively for engineers who already think in terms of memory layouts, RAII, pointer aliasing, and instruction caches. This is not a beginner's introduction to programming. It is a direct translation of everything you already know into a language whose compiler enforces the exact disciplines you currently maintain manually.

What You Will Learn

How Rust's ownership model formalizes C++'s RAII pattern into an unbreakable compile-time contract

The borrow checker's Aliasing XOR Mutability rule and how it eliminates dangling pointers and data races permanently

Lifetime annotations, non-lexical lifetime analysis, and pointer validity across complex scope boundaries

Rust's algebraic data types, traits, generics, and monomorphization, mapped directly to C++ templates and abstract base classes

Smart pointer types and interior mutability patterns replacing std::shared_ptr and std::weak_ptr

Fearless concurrency using the Send and Sync marker traits, scoped threads, and channel-based message passing

Async Rust and state machine compilation compared directly to C++20 coroutines

Zero-cost iterator abstractions proven against compiled assembly output

Systems-level optimization including SIMD intrinsics, cache-friendly layouts, lock-free atomics, and arena allocators

Seamless C++ interoperability using the Foreign Function Interface, bindgen, and the cc crate

Who This Book Is For

This book is written for experienced C++ developers, systems programmers, and low-level engineers building operating systems, embedded firmware, game engines, high-frequency trading platforms, and network infrastructure. Every explanation builds on concepts you already possess.

If you have ever traced a segmentation fault through a core dump, hunted a race condition across a million-line codebase, or written documentation that was the only thing standing between your code and a memory corruption vulnerability, this book was written for you.

Modern systems programming no longer requires choosing between safety and speed. Rust proves both are possible, at compile time.
