TLDR
Fred
An async client for Redis and Valkey
Example
use fred::prelude::*;
#[tokio::main]
async fn main() -> Result<(), RedisError> {
let client = RedisClient::default();
client.init().await?;
// convert responses to many common Rust types
let foo: Option<String> = client.get("foo").await?;
assert!(foo.is_none());
client.set("foo", "bar", None, None, false).await?;
// or use turbofish to declare response types
println!("Foo: {:?}", client.get::<String, _>("foo").await?);
client.quit().await?;
Ok(())
}

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!
