is2 VS cargo-watch

I used the rapidjson streams with my little embedded REST HTTP(s) server library: https://github.com/Edgio/is2/

Yup. Every user facing case mentioned has a corresponding flag. The non-user facing stuff, like being cross platform, is common sense.

GDExtension for Godot 4.2 supports hot reloading out of the box. To speed up your coding feedback cycle, use cargo watch to recompile your Rust code automatically when you save a Rust source file. Install cargo watch (if you need to):

I used cargo-watch here so that every time my source changes, the server will automatically restart and re-serve the updated code.

Rust isn’t great for letting you do FP things like other languages, but it does have the best type system imho which makes it the leading functional programming language right now imho. If you’re not using too many specialized python packages then I recommend using Rust instead, even for toy demos, as you can be more confident your code works without needing to run it and wait for a crash like you would in debugging python, and the tests also run faster in rust due to the incremental compilation. Use cargo-watch and you can retest your code every time you save your work.

I usually write a make command to cargo watch and rerun each test file : code file pair independently so then you won’t rerun your tests in other modules when you change the one you work on (faster but might miss stuff if you change API contracts which touch other parts of your codebase)

you can use cargo-watch to real time run tests on save in your attached vs code console session which is about as close to what you're asking as I think exists for rust

Note that cargo, by virtue of being a package manager for a programming language, is primarily going to be dealing with library packages. That's not because it can't manage executables (see cargo-watch for a particularly useful example), it's just that it's less common.

Unless there's a new issue, I think this is what was here: https://github.com/watchexec/cargo-watch/issues/249
