Ask HN: What are some good rust code to read to learn the language?

• Rustlings

  :crab: Small exercises to get you used to reading and writing Rust code!

  

I’d recommend working through rustlings rather than watching videos for basic rust understanding: https://github.com/rust-lang/rustlings. It is essentially a set of quick exercises to get you familiar with the language and how to fix common build errors.

For advanced Rust “Jon Gjengset” has posted a number of long-form videos on YouTube that are very good. Search for it.

For code examples, find a crate in an area that you are interested in and clone the repo. There are so many to choose from that it would be unfair to single anything out. Variation is good, not bad. If you see lots of generics and macros then skip it for early learning purposes.

Instead of writing something from scratch I’d recommend rewriting something you are familiar with in but in Rust. For example, if you did advent of code (if that is your thing) in python then write it in Rust and find a repo of someone who solved the same problems in Rust.

The Rust book is excellent. https://doc.rust-lang.org/stable/book/

• mini-redis

  13 3,602 5.5 Rust

  Incomplete Redis client and server implementation using Tokio - for learning purposes only

  

For learning async Rust, mini-redis repo is hard to surpass: https://github.com/tokio-rs/mini-redis

The code is simple enough for beginners to follow, but also complex enough to demonstrate Rust async in the wild. And best of all, the code is heavily commented!

You can follow the official Tokio tutorial to implement mini-redis incrementally: https://tokio.rs/tokio/tutorial/setup
