How is that not also stringly typed?

match Plugin::instantiate_async(&mut store, &component, &linker).await { Ok(plugin) => { match plugin .plugin_guest_oncallback() .call_ontimedcallback(&mut store, &callback_name) .await { Ok(()) => debug!("Successfully called oncallback for {plugin_path:?}"), Err(e) => warn!("Failed to call oncallback for {plugin_path:?}: {e}"), } } Err(e) => { error!("Failed to call oncallback for {plugin_path:?}!: {e}"); } } See th…

Ah, fair enough. So it is still stringly typed, it's just verified at compile time. Which I guess is true about all compiled functions ever.

Just add a "Huevos" prefix and a "S" at the end of the name, and suddenly you're thinking of delicious food instead.

For those who don't speak Spanish, "huevos rotos" are broken eggs (or scrambled eggs). Edit: I had to double check, because it seems that both translations are valid.

Ah, well, it's a dish, common name for it is "Huevos estrellados" in most places I think though. https://www.google.com/search?q=huevos+rotos&tbs=imgo:1&udm=...

Scrambled eggs would be "huevos revueltos"

Edit: in Spain at least. YMMV for other Spanish-speaking countries.

Agreed. There are almost certainly more people who know what "BGP" is than know what "Border Gateway Protocol" is. But it still would have been a favor to the original commenter to write "BGP (Border Gateway Protocol)". If you write just "BGP" you annoy the reader who doesn't know what it is; they'll think it's your fault. But if you write "BGP (Border Gateway Protocol)", they still won't know what it is but they won…

Someone linked a document a few weeks ago that address the topic of abbreviations and when the abbreviation is the common form it is acceptable to just use the abbreviation. I don’t think anyone in their right mind would open every article with HTML(Hypertext Markup Language) and CSS( Cascading Style Sheets). For networking it would be the same with BGP/OSPF/RIP.

But it is it a networking post? It's a networking blog in general, but this post is clearly targeted at people interested in a rust scripting language and should expect wider distribution.

With fast development cycles and a safe scripting language, Rust will find itself in every single programming niche. Server development, game development, desktop application development.

We keep saying "scripting language," but given that it's statically typed and JIT compiled, we could also call it an "application language." Relative to Rust, most backend applications can afford to trade off a little bit of performance for better development speed and readability.

Then also have a look at Mun: https://github.com/mun-lang/mun - Ahead of time compilation - Statically typed - First class hot-reloading Not sure how both languages compare though

Hi! Author here. Mun is super cool, but works slightly differently as far as I know. You compile Mun scripts outside of your application to a dynamic library, which can then be (re)loaded by your application. The advantage of that approach is that you can ship the compiled script with your application.

The downside is that it's not really possible to share types between the host application and the script as far as I know. They have something called called `StructRef` which does this a bit, but it's all runtime checks if I understand correctly.

If somebody here knows more about Mun, I'd be happy to be corrected. This is just my understanding from their documentation.

Hi! Author here. There's a couple of reasons. First, this language is syntactically a lot like Rust but semantically quite different. It has no references for example. We're trying to keep it simpler than Rust for our users. Second, using Rust would require compiling the script with a Rust compiler, which you'd then have to install alongside the application. Roto can be fully compiled by the host application. I think…

Are you saying Roto has no ambitions to be suitable as a gamedev scripting language?

It depends. I'd love to make a prototype using Bevy with Roto. What I'm trying to say is that if you only want something to make Rust compile faster, then Rust might the better option. If you want something that behaves more like a scripting language and you don't mind that is compiled at startup, then Roto might be good for that purpose (with the caveat that there are missing features of course).

Having not yet actually tried it, I assume I could compile at startup on a separate thread with no issues? This seems like a dream scripting language--or "application language" as someone else called it.

> game development I've been out of the loop for a while, but last I checked, the running gag was that there are more game engines written in rust than games. Have things changed? Any high profile games that were made in rust?

Afaik there still no high profile games in rust. But many if the complaints I’ve read of devs switching back from rust were about how hard it was to prototype something in rust. Having a scripting language with solid rust interop could help.
