Rust Systems Programming Mastering Performance, Concurrency, and Safety for Reliable System Software

by Kelvin D. Martel

Rust System Programming isn't just a reference, it's your definitive playbook for building low-level, high-performance, and reliable software, from bare-metal firmware to cloud-native services. Whether you're writing kernel modules, tuning network daemons, or crafting embedded applications, this book equips you with the patterns, practices, and deep-dive strategies to deliver mission-critical Rust systems with confidence. What You'll Learn " Safe Systems Design - Master Rust's ownership, borrowing, and lifetime model to eliminate data races and memory leaks - Architect modular services and drivers with traits, generics, and zero-cost abstractions " Concurrency & Asynchrony - Implement async/await with Tokio, Futures, and channels for scalable I/O pipelines - Leverage the actor model with Actix-rt for fault-tolerant, message-driven architectures " Embedded & no_std Development - Write firmware without the standard library: configure custom allocators, panic handlers, and entry points - Use embedded-hal traits, DMA, and RTIC to build interrupt-driven, power-optimized applications " Performance & Profiling - Optimize code with Thin LTO, full LTO, codegen-unit tuning, and profile-guided optimizations - Profile binaries using perf and FlameGraphs; analyze size with bloaty and UPX compression " Cross-Compilation & Containerization - Set up cross-toolchains, sysroots, and CMake toolchain files for ARM, RISC-V, and beyond - Build multi-architecture Docker images with Buildx and Yocto SDK for seamless deployment " Observability & DevOps Automation - Author robust CI/CD pipelines in GitHub Actions, GitLab CI, or Azure DevOps for automated tests and releases - Instrument logging with tracing, collect metrics for Prometheus, and implement distributed tracing with OpenTelemetry Who This Book Is For - Systems programmers writing kernels, device drivers, filesystems, or high-performance daemons - Embedded engineers building constrained-resource firmware and real-time applications - DevOps and SRE professionals automating builds, deployments, and observability for Rust services - Software architects standardizing safe, scalable, and maintainable system-level codebases With production-tested templates, end-to-end examples, and reusable code snippets, Rust System Programming is the essential guide to building future-proof, high-velocity, and resilient systems where every cycle and byte counts.
