redis-rs VS json

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.

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 ;-))

Oh wow. So serde_json doesn't roundtrip floats by default, it uses some imprecise faster algorithm https://github.com/serde-rs/json/issues/707

Good thing there's msgpack I guess.

tokio / hyper / toml / serde / serde_json / json5 / console

Serde JSON, an extension of the serde crate that enables the serialization and deserialization of Rust structs.

To serialize and deserialize data, we'll employ the popular serde crate along with serde_json. This will allow us to easily convert between Rust types and JSON when working with API requests and responses. For async operations we'll use the Rust futures crate.

From the Cargo.toml file above, we can see that the Perseus version at the time of publication is 0.4.2 and has the following dependencies that are common to both the engine side (server-side) and client side of a Perseus application: sycamore, serde, and serde_json.

serde_json

Number parsing uses a fairly naive but uses a lossless algorithm in musli-json. In serde_json they use a fork of lexical I haven't wrapped my head around. I wanted something simple to start with.

Your best best would be to use an enum. Either your own or something like the one from serde_json depending on what you are trying to do.

Don't do that if you care about memory usage. In your toy program, I wouldn't be surprised if memory usage was a lot better if you used Box instead. (even if it doesn't look like it, you can handle almost all the use cases of serde_json::Value with it, often not much less convenient)
