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.
