Write a mini-Redis in Rust: learn async programming with Tokio

This is a fine tutorial, but I must note that Rust async programming is a bad way to learn about Rust, and also is a bad way to learn about async programming. You should learn the basics of both Ruts and async programming elsewhere, and then try Rust async programming.<p>If you disagree, take a look at compile error in <a href="https:&#x2F;&#x2F;tokio.rs&#x2F;tokio&#x2F;tutorial&#x2F;streams" rel="nofollow">https:&#x2F;&#x2F;tokio.rs&#x2F;tokio&#x2F;tutorial&#x2F;streams</a> and think again. That is in fact NOT atypical. (Amusing paradox: you get less errors once you learned, but you get the most terrible errors when you are the least equipped to deal with them.)<p>To slightly exaggerate, I spend about half my time in Rust support chat channel in my locality to discourage people from trying Rust async programming without getting the basics of Rust. Their logic go: I am interested in Rust only for async network programming, I am not interested in Rust sync network programming, I also learn best by try using something in a project straight away, so I will just learn Rust by writing a Rust async programming project! This literally 100% fails, but people who do this really really want to do it that way, and discouragement doesn&#x27;t really work, and they get really frustrated, and... I am not sure how to solve this.

Hold on, there is way more documentation than before ! Things like “when to use std::sync::mutex vs tokio::sync::mutex” were not there 1 version ago ! additionally, framing and streams will be of great help for my current project!

Redis is one of those things that deceptively looks like it would be easy to build in the eyes of a beginner engineer but in reality is a great technical achievement.

This is pretty neat. I’ve always thought Redis was a good way (and arguably a better one) to get to grips with network code in a new language&#x2F;runtime.<p>I did it for asyncio, Go, Clojure and a few other things.
