Rust enums are far more than a set of constants. They carry data, drive state machines, replace null, and unify error handling. This guide walks you from basics to recursive enums with real code examples.

When packet rates surpass 2 million per second, the Linux network stack simply gives up. It’s like your doorbell won’t stop ringing, but you never have time to open the door. Let’s talk about bypassing the kernel.

Build a production-ready async microservice with Rust and Axum: job queue, background workers, exponential backoff retries, and graceful shutdown. Includes full project structure and Docker example.

Master graceful shutdown for Rust Axum services: listen for SIGINT/SIGTERM, refuse new connections with with_graceful_shutdown, stop background tasks via CancellationToken, set timeouts, and integrate with Docker/Kubernetes termination — protect data integrity and user experience.

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.

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.
