mask VS json

Another alternative I'll add is my mask CLI tool. It reads a markdown file and parses it for a command structure. Markdown code blocks are used to define bash/zsh/python/ruby/node scripts all within a single file.

I also build and maintain a Rust-based CLI tool called mask. While this doesn't run in production, it powers everything from my local development workflow to my CI and production deployment flow.

It is a new project that is currently in Alpha stage. You can download from my GitHub account and play with it. It is built using Svelte, Nw.js, and mask script running.

I mentioned elsewhere in this thread that I built a jigsaw puzzle website [1] with a Rust API backend and I launched it last week. It definitely took longer than if I had used Node, but I enjoy working with Rust much more.

Apart from that website, I have also open sourced a Rust CLI task runner [2] which uses markdown files as a command definition format. This is probably the most important tool I've ever written, as I have used it every single day since.

At the top level, there are three things: the server directory, the UI directory, and a maskfile.md file for using mask. Mask is a great tool for running scripts on your project. I use it all the time.

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.

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)
