Rust

This is a blog post that really is about C++, but with a look at how Rust does things. So, this is an interesting C++/Rust comparison for once.

Last week I basically duplicated the serialization code to provide better debug output.... today, I see this pass in my Mastodon feed. 😀 Well... what are the odds... most likely close to 100% according to how the universe seems to operate.

Hi rustaceans! What are you working on this week? Did you discover something new, you want to share?

Kellnr, the crate registry for Rust got an update. The latest version contains bug fixes and dependency updates. If you are interested in hosting private crates that must not be on crates.io, check it out.

A short post on how variable names can leak out of macros if there is a name collision with a constant. I thought this was a delightful read!

Hi. I've been learning Rust for a while, and I want to take on an actual project now to learn even more. I need to be pointed in the right direction for one aspect of the affair, and I hope someone here can help me.

I want to create a deck tracker for Hearthstone that runs natively in Linux. This is, on the back end, a fairly simple matter of parsing a constantly updated file that tracks everything that happens in the game. On the front end, however, I want to create a window that sits on top of the fullscreen Hearthstone window and shows me stuff. The "stuff" doesn't have to be images or anything fancy, I'll take whatever I can get, but I don't know how to get started on this part.

So the task is as follows: Create an overlay on top of the fullscreen Hearthstone client, preferably under Wayland, and update it constantly with new information about cards drawn, cards left in deck, that sort of thing.

How do I tackle this problem? Are there any crates that'll let me create such a window and render stuff to it? How would you approach the problem?

Thanks in advance.

I've always been curious about this. If I were to take a snapshot of a git repo at a particular point in time, who would be the top contributors by active lines of code? And then, what type of files have they contributed the most? So I built this little tool.

I've been wanting to learn rust for quite some time now and this was one of my first projects in it. It was a lot of fun!

It uses git under the hood to obtain the information and it's nothing fancy, but keen to hear what you think.

Hi all.

I want to develop a plugin system within my program, and I have a trait that functions defined by plugins should implement.

Currently, my code gets all the functions in a HashMap and then calls them by their name. Problem is, I have to create that hashmap myself by inserting every function myself.

I would really appreciate it if there was a way to say, suppose, all pub members of mod functions:: that implement this trait PluginFunction call register(hashmap) function. So as I add more functions as mod in functions it'll be automatically added on compile.

Pseudocode:

Files:

src/
├── attrs.rs
├── functions
│   ├── attrs.rs
│   ├── export.rs
│   └── render.rs
├── functions.rs
├── lib.rs

Basically, in mod functions I want:

impl AllFunctions{
    pub fn new() -> Self {
       let mut functions_map = HashMap::new();[[
       register_all!(crate::functions::* implementing PluginFunction, &mut functions_map);
       Self { function_map }
  }
}

Right now I'm doing:

impl AllFunctions{
    pub fn new() -> Self {
       let mut functions_map = HashMap::new();[[
       crate::functions::attrs::PrintAttr{}.register(&mut functions_map);
       crate::functions::export::ExportCSV{}.register(&mut functions_map);
       crate::functions::render::RenderText{}.register(&mut functions_map);
       // More as I add more functions
       Self { function_map }
  }
}

Hey all, just sharing a small, single-page site I built using Leptos + TailwindCSS, mainly intended as a demo for an API I built using Axum. Hope someone also finds it interesting!

I'm sharing this site and not the API itself cause I figure it's easier to look at and understand, but if you want to roast some code I would appreciate any feedback you have on the API itself (repo here). Trying to leave the front end developer scene so this is the first API I've tried building, fairly basic but it was fun (I am a big Civ V fan - I hear it's inspired by some niche thing called human history?).

Edit: whoops, looks like the link didn't get set cause I put an image - the site is available here, and the repo for it is here. The live API is available here

In case you haven't seen it, here's a talk regarding Rust's integration into the Linux filesystem that gets completely derailed at The Linux Storage, Filesystem, Memory Management and BPF Summit.

After reading Drew's pitch to the rust community to write our own kernel, I've searched for "linux abi compatible rust kernel" and found "Asterinas". Surprised that it is not mentioned here
