As a C++ developer I shrug at those size numbers, but I’m glad you are a happy with Rust.

OP's sort of being misleading when they say they "rewrote it in Rust", IMO. They're still using HTML and JS for their UI, rather than a native solution. The size/perf improvements mostly just come from using the OS' native engine instead of bundling Chromium.

As a rust developer, I do too! Those are not representative of rust GUI/3D etc desktop applications. I've made some pretty complicated stuff with 2D and 3D graphics, lots of functionality; expected size is 5-15Mb on Windows, and 10-25Mb on Linux. Less if you don't need 3D.

Strip the Linux binaries with strip(1).

What do you think would be more in line with what you've seen in the past? There's definitely room to keep optimizing.

<25Mb for the executable. For the use case the web page desribes, probably <15Mb. It usually comes down to dependencies used.

Interesting. I'd love to get our app size down further, under 15MB would be great.

is there a UI framework production ready yet in rust??? because for Tauri at least you can use JS which is fine

yeah slint, which is most similar to Qt

lol when you click through to this site from HN it redirects to https://upload.wikimedia.org/wikipedia/commons/d/d4/Human_fa...

if you open in new tab or copy/paste in new tab it does not.

Funny for sure, but not novel. JWZ also doesn't let his web site linked from HN. Example link (that only works properly when you copy paste, opinionated rejection otherwise): https://www.jwz.org/blog/2024/06/mozillas-original-sin/

EGUI

iced is the best IMHO

Should we do a c++ rebuild

If you use FLTK you can start a binary with no dependencies at 100KB.

That has nothing to do with Rust and everything to do with Tauri.
