Show HN: I wrote a Rust book ending with a Redis clone
A self-published Rust book guides readers through building a Redis clone as the final project, teaching systems programming concepts hands-on.
Background
- **Who/What**: A self-published Rust programming book that teaches the language by guiding readers to build a Redis-like in-memory database as the final project. The author is a developer named Shan that goes by shankhan3 on Gumroad.
- **Why it matters**: Rust is a systems language known for memory safety and performance, but it has a steep learning curve. Project-based books (ending in a realistic clone like Redis) help learners move past toy examples and into production-style code. Redis itself is a widely used open-source key-value store (caching, message queues, real-time data) — building a clone forces learners to handle networking, protocol parsing, concurrency, and persistence in Rust.
- **Prior context**: This is a "Show HN" post (Hacker News), meaning the author is directly presenting their work to the tech community. Similar books (e.g., "Writing an Interpreter in Go" or "Build Your Own Redis from Scratch") follow the same pedagogy: end with a recognizable, non-trivial system. The Rust ecosystem has strong demand for hands-on resources beyond introductory syntax.
