Exactly. A rust panic will call the panic_handler, implemented there: https://github.com/Rust-for-Linux/linux/blob/459035ab65c0ebb... So accessing an array out of bound will have a runtime check that will cal

Yes, the .slint file without a .rs file is a complete example. They can be viewed with the online editor. For example, the cells: https://slint-ui.com/releases/0.2.2/editor/?load_url=https:/... The cell

I've used KDevelop and QtCreator to write C++, and they had pretty good auto-completion and semantic information way before clang came along. Example, these blog posts from 2009 showing that KDevelop already had semantic highlighting,

The goal is to support more higher level languages such as Python and Go in the future. The reason to start with these languages is that: Rust is the implementation language. C++ is another compiled language which is much used in the indust

There is also a free (as in beer) license: https://slint-ui.com/ambassador-program.html That should cover your need for your hobby project. For your OSS work, you can license your code in MIT, BSD, Apache, or any license co

Cargo links all the rust code together in a static binary, but the C/C++ libraries can be linked dynamically, and in the case of something like Qt, most certainly are. Since most important part of Qt are LGPL, you can use this crate an

The thing is that Qt is a C++ toolkit written in C++ and meant to be used from C++ with its C++ API. Especially if we want to use QtWidgets, the API surface is huge . There are a bunch of bindings with different language, but even the ones

"containers" was not in the list. There sure is some overlap with what Qt offers that most language offers (Containers, Networking, Database, threading, ...). But purely in the context of making a UI library, there is still a hug

Well, that's the thing. In my (biased) opinion, that crates doesn't have any of the problem mentioned. - The qmetaobject crate tries to be idiomatic rust and to be used without any C++ - As far as the user is concerned, there shou

Sorry, I did not mean to say that this was representative of the overall experience. On the contrary, I'm usually quite satisfied with the compiler messages. Thanks for your work!

The worst error message was basically no error message. After I made some big refactoring to my project, cargo would just exit with: error: could not compile `the_project`. And nothing else. No hint of what the problem is. It then t
