Tokio

The tokio::select! macro has always been a blind spot for rustfmt. better_tokio_select uses match syntax to fix this, so your async Rust code can finally be auto-formatted.

CPU was fine, memory was stable, no recent deploys — but error rates hit 3.4%. After comparing 6 outage reports across Node.js, Go, and Java, we finally understood how async systems actually fail, and where Rust+Tokio’s compiler draws the line.

It compiles. It runs. It even passes stress tests… until production catches fire. Let’s talk about that classic async Rust pitfall everyone hits.

A hands-on guide to building a usable mini Actor framework in Rust from scratch: Actor, Addr, spawn, supervise, a simple registry, message passing, and HTTP interaction.

When traffic surges like a flood, equip your Rust microservices with four gates—rate limiting, backpressure, batching, and middleware—using Tokio + Tower. Keep P99 steady and make speed happen in order.

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.
