LIVE: bribing myself to work on async Rust TCP connections
In this session, I continue the journey of building a basic load balancer from scratch using Rust. We take a deep dive into asynchronous programming with Tokyo, explore the nuances of TCPListener vs. TCPStream, and tackle the "fun" of move semantics and lifetimes in async blocks.
Beyond the code, we have some great community discussions about the reality of being a full-time creator, the "cognitive debt" of over-relying on AI for coding, and why I’m still a beginner-ish at Rust despite what my GitHub might say. Grab a cup of Yorkshire Gold and let's get into some "whimsy-driven development."
In this stream, we cover:
Asynchronous Rust: Implementing tokio::spawn and understanding async move.
Networking Fundamentals: Handling multiple concurrent connections with listener.accept().
Error Handling Patterns: Moving from custom error enums to more idiomatic patterns.
Developer Philosophy: Why building things manually is still the best way to learn in the age of AI.
Setup Tour: A look at my NixOS configuration on the Framework 13 Pro.
