TLDR

use fred::prelude::*; #[tokio::main] async fn main() -> Result<(), Error> { let config = Config::from_url("redis://localhost:6379/1")?; let client = Builder::from_config(config) .with_connection_config(|config| { config.connection_timeout = Duration::from_secs(5); config.tcp = TcpConfig { nodelay: Some(true), ..Default::default() }; }) .build()?; client.init().await?; client.on_error(|(error, server)| async move { println!("{:?}: Connection error: {:?}", server, error); Ok(()) }); // convert responses to many

Back Story

The goto Redis client for Rust is called redis-rs. It has over 3k stars on Github. but I found it very annoying to use because I quickly found out that if you want to set any value you had to get a mutable reference to the underlying client. Which meant great pain to store Redis client in the global scope. People who do not know what a mutable reference is consider the let keyword in JavaScript. you can mutate or change a variable that is initiated with let.

The other annoyance I had that it didn't support RedisJson which was a bummer because it is very helpful if you store anything other than String key value pair.

Fortunately then I found Fred. Fred is a beautiful piece of engineering. It solved all of the problems I had with the redis-rs package. It is async friendly, it supports RedisJson and most importantly it doesn't require a mutable reference to set value.

It also has a lot of other great features. Consider starring the project and spreading the words!
