Possibility of integrating rust as modding (GUEST) language

[PPakalns]

It could be done using wasmtime, maybe even using wit supported by wasmtime.

About:

First class functions. Or at least the ability to call an arbitrary function with an arbitrary number of arguments from a script. Without this feature, you would need to separately generate code for the bevy bindings which is painful and goes against the grain of BMS.

I think that this should be supported. In worst case with introducing additional Value type that is used to simulate necessary properties, it should be?

Wanted to rise this topic as I couldn't find this possibility mentioned in this repository.

Rust is not a scripting language, but compiles fast enough and has wide variety of crates that would be useful in complex mods, and when performance matters (wasm).

Would be interesting to know.

Hi, this has been discussed a little over at:#119.

Generally I am personally not going to be adding new languages any time soon, but I would encourage experimentation of this kind (and adding new language plugins can be done via external crates too).

I am under the impression this should be possible, i.e. it looks like wasmtime supports creating arbitrary functions and passing them to the script: https://docs.rs/wasmtime/latest/wasmtime/struct.Func.html#method.new.

But I have not interacted with WASM at all and I am not informed on its limitations, happy to help with specific issues though!

Thank you for your answer :)
