I can see this being useful in combination with Piston[1] to achieve scripting for game engines, in the same way Lua is normally used. Rust as a core for a game engine seems like a really great idea, considering the speed and safety benefits it provides. [1] https://github.com/PistonDevelopers/piston

Javascript seems like a great contender in this space to me. Btw, as well as using nodejs / v8, there are also Rust bindings for SpiderMonkey (Mozilla's JS engine): https://github.com/servo/rust-mozjs

(not super user-friendly yet, as this mainly exists for Servo - but there's enough here to embed Javascript scripts in your Rust projects!)

Could be killer if combined with electron.

If the goal is having a fast "business-rules engine" coupled to a pretty HTML5-based app-wrapper, one of my own projects is to combine Electron with the Erlang VM. Rather than trying to go whole-hog on linking the two worlds together at a process level, I've just embedded an Erlang release into the Electron package, which decompresses itself to the user's Library/APPDATA dir on Electron startup, transparently registe…

You might want to look into BERT [0], I think there is a JavaScript library. We used it a few years ago to call Ruby from Erlang, it wasn't fast at the time, but it did what we needed it to do.

Earlier quoted context omitted.

Did Yehuda ever open source or complete a similar abstraction like this but for Ruby? I remember someone mentioning to me he was working on it. I have a longstanding todo (though I have no motivation because I currently have no use for Rust or Ruby) to try something similar though I remember my initial attempts having trouble with how Ruby's C API expresses some values.

I'm actively working on it ( https://github.com/tildeio/turboruby ) and in fact was racing @dherman to finish. He beat me by a mile :( but I hope to wrap up a usable first version soon.

I'm looking forward to it! I really want to flex some Rust muscle at work for our performance critical stuff.

Honest question: Why would someone use Node instead of a Rust web framework when writing part of the code in Rust anyway?

- Node has full garbage collection. Rust has some very clever memory-handling, but it's not quite the same.

- Node is javascript. You may want to run the same code on client and server, and it's simpler than compiling Rust to JS.

- There may be JS libraries you want to use.

I could go on.

Since both node and Rust use libuv for parallelism. Is it possible to provide the node libuv pool to rust so that they share a single bound on parallel operations?

Also, can I use Neon for async callbacks?

Give me this but with Elixir and Im sold.
