Thanks for using wasmtime! I worked on the component bindings generator you’re using and it’s really nice to see it out in the wild. To elaborate a bit further: wasmtime ships a [bindings generator proc macro]( https://docs.wasmtime.dev/api/wasmtime/component/macro.bindg... ) that takes a wit and emits all the code wasmtime requires to load a component and use it through those wit interfaces. It doesn’t just check th…

Thanks so much for your work on this! So far it's been a good pattern for adding hot-reloadable logic to my Rust projects.

Next up I'm hoping to integrate this stuff into a game so you can have hot-reloadable game logic, with the potential for loading and sandboxing user-created mods.

- The best package manager in the world, bar none. Compiling, linking, and platform difficulties disappear. The devops/devexp is next-level sublime. - "low defect" software without much work.

It’s also a pleasant language to work in. I love that everything is an expression, I love match statements, I love that structs and enums are full powered, etc.

I know, practically self-documenting code!

I'm not trying to pick on tokio, it was just a public link demonstrating that the syntax can get to be a bit much

So no clear examples?

In the Java/Groovy space, Jenkins and Gradle are the obvious ones. I'm less familiar with the Lua world (not a gamedev), but this is an example of the kind of thing I'm imagining— a build system / task runner that's half lua and half C/C++: https://github.com/xmake-io Having a modern on-prem replacement for Jenkins/Rundeck built in rust and exposing a roto interface rather than yaml definitions sounds like it would b…

So, how is Rust better than these? What does it have that these lack?

What does Rust have that other languages with these properties don't?

Java 8 was released in 2014, since then Optional is in the standard library and a rather common pattern. Like Rust you can use LLVM to compile Java to WASM (JWebAssembly), and there's also TeaVM for turning a project into an optimised WASM application and CheerpJ for running a JVM in WASM.

It was rather messy to use cargo on handheld ARM, it didn't spark joy so I kind of stopped trying after a while. Mostly I use Rust as a dependency I don't need to touch, but when I've programmed in it I didn't feel like cargo was that big of a thing. Maybe I would feel another way if the frame of reference was only like webpack or Pip or something.

Package management, expressiveness, community, open source code availability... a helpful compiler and goated type system.... overall sanity

Of all the examples of crazy Rust code you could have picked, you chose that one?

Is adding ‘a really too much for you?
