I just attempted to write up a simple Minesweeper game with Iced. No bells or whistles, but it works:

https://github.com/veniamin-ilmer/minesweeper

On one hand, I find it pretty cool I built a clear cross platform GUI with actual functionality, within only 200 lines of code.

On the other hand, I can't help but see how inefficient it seems. If I ever need to modify any of the objects, I need to redraw all of them. The structure of the view method makes me think it is very difficult for Iced to maintain a "virtual DOM" to only make delta changes.

Am I wrong? Is there a more efficient way to do this in Iced?

Edit: I just found this - https://github.com/iced-rs/iced/pull/1284

As the library matures, the need for some kind of persistent widget data (see #553) between view calls becomes more apparent (e.g. incremental rendering, animations, accessibility, etc.).

If we are going to end up having persistent widget data anyways... There is no reason to have impure, stateful widgets anymore!

So it seems like Iced plans to have an internal "persistent widget storage", which in abstracted away from the user. But it is quite unclear to me how they would accomplish this, considering the view method doesn't provide an ID for any of its objects, so it would not be easy for Iced to determine the difference between updates.

I've been trying to find something that allows me to see performance visualizations in my rust programs, but I haven't found any so far. I'm looking for something that's like SnakeViz in Python, but for Rust. If there's a better way to get about doing this, I'm all ears.

Hi everybody, I'm new to Rust.

So, I have a struct Panel which contains a data widget which implements the trait Widget I have to implement a function for Panel that uses another function that requires a type that implements Widget.

I tried Box<T>, Rc<T>, Box<dyn Widget, &T, but nothing, always compiler errors.

How can I fix this?

Lib.rs has previously been editorializing the crates within the search algorithm on their site based on their own personal preference. However, they recently have taken it a step too far in labeling the bitcoin repo as unmaintained despite active development taking place for the past several years. Several others have also taken similar actions.

Quoting the author

I’ve starting working on a lemmy front end called lemmy-ui-leptos using leptos, a Rust UI framework with isomorphic support, and tailwind + daisyUI for the component styling. This could eventually replace the frankenstein’s monster that lemmy-ui has become.

From the release notes:

We are happy to release the new version of ratatui mouse, a community-maintained fork of tui.

In this version, we have introduced a new Scrollbar widget and enhanced the functionality of existing widgets like Block and Barchart. We have also made significant improvements to the stylization/widgets API, ensuring a smoother experience when creating TUIs. Additionally, we have addressed various bugs and implemented enhancements to optimize the overall user experience in TUI development.

Here is a blog post highlighting the prominent new features and providing practical examples of their usage: https://blog.orhun.dev/ratatui-0-22-0
