From zero to hero WebSocket transport layer implementation, every line of code has a story, performance so good it makes you wonder if the compiler is cheating
Step-by-step guide to building cross-machine communication Actor systems with Rust, with performance that will make you question reality
Using a coffee shop metaphor, build a practical mini Actor framework in Rust covering Addr, spawn, supervise, a registry, and message passing.
Bold claim up front: stability is not “slow.” Stability is making “fast” happen in an orderly way. With the gates placed at the right spots, even a flood can be channeled into rivers. Think about a subway during Monday rush hour. Entry turnstiles regulate inflow, platforms enforce headcount, trains add extra cars, and the PA system orchestrates everything. That is exactly what microservices must do under high concurrency. Your Rust service needs the same four gates: rate limiting, backpressure, batching, and a smart brain of middleware. ...
If async tasks keep waking you up at 3 a.m., this guide is for you. We’ll build a resilient microservice with Rust + Axum that processes jobs reliably, scales well, and shuts down gracefully. The mental model: a busy coffee shop An HTTP request is like a customer placing an order. You shouldn’t block the cashier until the coffee is brewed. Instead: accept the order, hand it to the kitchen, and move on to the next customer. Our job queue is the order slip; workers are the baristas. ...
Rust Axum Graceful Shutdown, The Ultimate Guide: Fix the pitfall 99% of engineers hit Follow Moshou Coding on WeChat to learn Rust the easy way. Do these production nightmares look familiar? You reboot the server and lose user data. DB connections fail and transactions get rolled back. WebSocket links drop and the UX craters. The root cause is a detail 99% of developers overlook — Rust Axum graceful shutdown. Let’s make it practical and friendly while staying production‑grade. ...
You’ve heard the rumors: Rust is blazing fast and memory‑safe, but writing backend services feels intimidating. What if it could feel like building with LEGO — intuitive, composable, and fun? Enter Axum, a modern Web framework built by the Tokio team. In this tutorial you’ll: Understand Axum’s core concepts: Router, handlers, extractors Work with path parameters, query parameters, and JSON Add shared state with Arc<Mutex<T>> Install middleware such as structured tracing Step 1: Add dependencies axum = "0.7" tokio = { version = "1", features = ["full"] } Or via CLI: ...
Friend, have you had a night like this? On the screen, the Rust compiler’s scarlet errors grip your project by the throat. Lifetimes, ownership, borrow rules — the guardians you’re usually proud of suddenly feel like a never-ending lecture you just want to shut up. Right when you’re about to give up and smash the keyboard, a word glows in your mind with devilish temptation — unsafe. It feels like a cheat code, a God-mode switch that makes all red squiggles vanish. You wrap those “problematic” lines inside a sacred block, type cargo build… Success! Silence. ...
Follow Rexai Programming on WeChat to learn Rust the easy way. Forget the heavy “thread” mental model from your OS class. Today, I’ll show you a delightful trick about Tokio. You think tokio::spawn creates a thread? Nope. It gives you something smarter, lighter, and frankly a little sneaky: the ability to harness massive concurrency at a shockingly low cost. This is one of Rust’s secret weapons in backend development. Ready? Let’s reveal the trick. ...
Your Rust async code is a “liar”—and I’m going to strip its state machine down to the bones. Have you ever written an async function, happily called it, and then… the program just ended with nothing happening? You stare at the screen: Where did my code go? Where’s my println!? Did I just run emptiness? Don’t panic. You’re not alone. Welcome to the world of Rust async, where the first rule is: what you see isn’t necessarily what’s happening. ...
