fastrand VS serde-yaml

On the frontend, while Puzzle Panda is mostly built with Svelte, I do load a small wasm package which exposes a seedable random number generator from fastrand.

Either https://github.com/chyh1990/yaml-rust or https://github.com/dtolnay/serde-yaml for parsing the YAML config file that markdownlint uses

Serde for most of your input and output formats, with the serde-yaml and csv crates for format backends.

serde_yaml

This is especially useful for data deserialization: Just by implementing the Serialize and Deserialize traits from the serde crate, the (almost) universally used serialization library in the Rust world, we can then serialize and deserialize our types to a lot of data formats: JSON, YAML, TOML, BSON and so on...

FYI, I opened pull requests for serde_json and serde_yaml to explicitly enable indexmap/std, and dtolnay already merged and published them both!

Pair that with Serde for serialization/deserialization (JSON, TOML, YAML, CSV/TSV, XML, URL query strings, etc.), Figment for configuration, and ignore for filesystem traversal with blacklist support, and Rust is a real joy for writing CLI utilities.

I see that are packages like https://github.com/dtolnay/serde-yaml and the parser where serde is built on that give a Yaml representation, but I don't see any way to walk through it in a generic way with a Visitor.

With the understanding we’ve built of the runtime environment, I feel ready to start porting a simple CLI I’ve built in Rust to run in WebAssembly as a service hosted in Hippo. [The project we’ll start with is J2Y(https://github.com/smurawski/j2y/tree/1-getting-started) – which is a little Rust application that converts JSON to YAML or YAML to JSON. We’ll adapt this to, depending on the target, either be a CLI or a WebAssembly binary to run in WAGI. The heavy lifting of the conversion is done by the serde-json and the serde-yaml crates.
