Add support for more scripting languages

[naturallymitchell]

Is your feature request related to a problem? Please describe.
Lua is only one good scripting language. Others, especially native Rust ones would be good to support.

Describe the solution you'd like
Make each language a plugin or feature, perhaps.

Describe alternatives you've considered
Forking actix-lua to make actix-otherlang, but that would be very limited and stale.

Additional context
Some good looking languages: Ullage, Molten, Rulox, Tox, and SimpleJIT Demo.

Embedding languages are, by design, tightly coupled with the host. They also have their own trade-offs, binding interfaces, memory management, performance profile,...etc. Switching to a new language is basically a total rewrite.

actix-lua picks Lua specially because:

1. coroutines make asynchronous programming easier.
2. sophisticated module cache and reloading.
3. Lightweight and easy to use.

So, I think this issue is too board and not actionable.

[naturallymitchell]

Okay. Could you please advise then how to go about similarly embedding Ullage, for example?

[poga]

I have no experience in Ullage or other languages you've mentioned. Sorry.

[naturallymitchell]

Well, off course not. Lua is 26 years old, and these Rust-based languages are on average 1 year old. Ullage looks like the most interesting one. If you have a couple min, I'd really appreciate your views on using one of these similar to how we're using Lua now.

[poga]

As I said, if you want to make bindings between actix and the language you want, you better off start from scratch.

It's unrelated to actix-lua and I can't help you with it.

Ok, ty @poga
