Introduction: Why Safe C Interoperability in Rust Is So Hard When I first started using Rust in real-world systems, the most painful bugs didn’t come from my Rust code at all—they slipped in at the FFI boundary with C. Rust’s… Read More »Top 7 Strategies for Safe C Interoperability in Rust (Without Footguns)
Introduction: Why Structured Logging Matters for Rust Axum APIs When I started building production Rust HTTP APIs with Axum, I quickly realized that basic println!-style logs weren’t enough. Once traffic, background jobs, and external integrations entered the picture, I needed… Read More »How to Add Structured Logging to Rust HTTP APIs with Axum Middleware
Introduction: Why Embedded Rust HAL Crates Matter When I first started experimenting with Rust on microcontrollers, the biggest hurdle wasn’t the language itself – it was finding the right hardware abstraction layer (HAL) to build on. In no_std environments, embedded… Read More »Top 7 Best Embedded Rust HAL Crates for Real-World no_std Projects
Introduction: Why Rust Custom Allocators Go Wrong So Often Whenever I talk to performance-focused Rust developers, I hear the same story: the default allocator is "fine," until it isn't. That's when people reach for Rust custom allocators or swap in… Read More »Top 7 Rust Custom Allocators Mistakes That Kill Performance
Introduction: Why the Rust Borrow Checker Feels So Hard When I first moved from languages like Python and Java to Rust, the Rust borrow checker felt less like a safety net and more like a wall. Code that seemed obviously… Read More »Taming the Rust Borrow Checker: Practical Refactoring Patterns
Introduction: Why Tokio Runtime Mistakes Hurt So Much Tokio makes async Rust feel deceptively simple: add async, spawn a task, and everything seems fine in local tests. But in my experience, the real pain only shows up under production load,… Read More »Top 5 Tokio Runtime Mistakes That Quietly Kill Your Async Rust
Introduction: Why Arc, Mutex, and RwLock Matter in Rust When I first started writing concurrent code in Rust, I quickly ran into a core tension: I wanted multiple threads for speed, but the borrow checker refused to let me share… Read More »How to Choose Between Arc, Mutex, and RwLock in Rust Concurrency
Introduction: Why integrate Rust FFI with C in existing CMake projects? When I first started adding Rust into an old C codebase driven by CMake, I wasn’t trying to rewrite everything; I just wanted safer, faster components without breaking the… Read More »How to Wire Up Rust FFI with C in a CMake Project (Step‑by‑Step)
Introduction: Why the Rust Actor Model Is Having a Moment When I first started building concurrent services in Rust, I quickly realized that the usual shared-state patterns from other languages didn’t translate cleanly. The Rust actor model, especially as implemented… Read More »Rust Actor Model in Practice: Designing Robust Message Passing with Actix
Introduction: Why Memory Contexts Matter for Rust pgrx Extensions When I started writing my first Rust pgrx PostgreSQL extension, I assumed Rust’s ownership model would “just” keep me safe. Then I hit my first crash caused by PostgreSQL freeing memory… Read More »Mastering Memory Contexts in Rust pgrx PostgreSQL Extensions
Introduction: What You’ll Build and Why the Rust WebAssembly Memory Model Matters When I first started compiling Rust to WebAssembly, everything seemed fine for simple functions that just added two numbers. The moment I tried to pass strings, structs, or… Read More »How to Master the Rust WebAssembly Memory Model and Host Bindings
Introduction: Why Rust ECS Game Development Is Exploding Rust ECS game development has gone from a niche experiment to something I now see in serious prototypes, jams, and even production pipelines. The combination of Rust’s memory safety and an Entity-Component-System… Read More »Top 7 Rust ECS Game Development Techniques for Safe High-Performance Play
