A step‑by‑step Axum guide to build a modern high‑performance Web service: routing, path and query parameters, JSON, shared state, and middleware (tracing, CORS) with complete code samples and best practices.
Rust unsafe isn’t a toy — it’s a blood oath: 6 YOLO mistakes that will blow up your code
Don’t treat unsafe like a get-out-of-jail-free card. With practical examples, this article dissects 6 common unsafe pitfalls: silencing the compiler with duct tape, dereferencing random raw pointers, violating borrow rules inside unsafe, reinventing wheels, abusing unsafe impl, and skipping Safety comments — helping you build the right risk mindset and usage patterns.
Stop treating tokio::spawn as a thread! I launched 1000 tasks in 2 seconds and the system stayed calm
tokio::spawn is not a thread but a lightweight task. Under Tokio’s scheduler you build highly concurrent services with sleep, timeout and select — 1000 tasks in 2 seconds with negligible overhead.
