PickleDB VS redis-rs

I would think one that is based on Serde, like PickleDB, could be a good choice.

Pickle-rs is another I may build a clone of.

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.

staticpi, is a websocket forwarding service. Basically, it enables one to keep a Raspberry pi, or any computer, “connected”, in order to send and receive messages to and from any client, without having to deal with a static IP address, open ports on your router, or similar. Built in Rust, using axum, which in turn uses tungestine-rs for the websocket connections, tokio, sqlx, redis-rs and others.

redis (use streams and pubsub)

Are you addressing the long-standing issue that the redis client has related to dropped connections?

I switched to LALRPOP for gluon but I still use combine in https://github.com/mitsuhiko/redis-rs and some other projects which need to parse "protocols" (less need for good error messages/error recovery and more need for speed).

The project is implemented with MongoDB Rust driver and redis-rs crate.

redis-rs, a Rust library for Redis with both high and low-level APIs

I think the redis crate was a well-organized API library. It's still sometimes hard to know the right things to make public and I think they nailed it.

We have been using it before it got merged in redis-rs (we upvoted the PR here https://github.com/mitsuhiko/redis-rs/pull/319 a while back ;-))
