cxx-qt VS crates.io

My employer, KDAB, is building an excellent Rust binding for Qt: https://github.com/KDAB/cxx-qt

You can use cxx-qt or qmetaobject-rs. Or use Slint

Rust has several Qt bindings. The most popular are Ritual, CXX-Qt, and qmetaobject. Ritual is not maintained anymore, and qmetaobject doesn't support QWidgets. So CXX-Qt is our best bet for now.

Qt bindings for Rust also exist, although I'm not sure how mature they are: https://github.com/KDAB/cxx-qt/

We're getting closer, but you're still likely to run into missing features in CXX-Qt at this point. If you do, please report it on GitHub!

This is no longer required in CXX-Qt as of this week (https://github.com/KDAB/cxx-qt/pull/428). Next release coming soon.

From my understanding KDAB isn't trying to "replace" Qt. They're working on cxx-qt to make using Qt and Rust together much easier.

I second this. I wrote an internal Qt/QML app that ran on Windows, Linux, Android, and Raspberry Pis. We had ~20 Raspberry Pi's running this app in kiosk mode. If only KDAB/cxx-qt[1] were ready there, I would have done as much as possible in rust .

All the code discussed in this article can be accessed through this repository. For integration with existing projects consider using keyword_extraction crate available on crates.io.

So, be sure to double-check your critical libraries and be sure their alternatives exist in the Rust ecosystem. There’s a good chance the crates you need are available in Rust's crates.io repository.

The previous section was very simple, this section is also very simple but introduces us to cargo which is Rust's package manager, as a JS dev my mind goes straight to NPM.

Now, there has to be a place where all these packages come from. Similar to npmjs registry, where all node packages are registered, stored and retrieved, Rust also has something called crates.io where many helpful packages and dependencies are registered.

Before proceeding, let's check https://crates.io/, the official Rust package registry.

The most thrilling aspect has been the joy of writing the backend. It's like every struct, enum, and method in Rust forms this interconnected Multiverse of code , which you can see in crates.io which is best Documentation experience I Ever Had.

5. Crates.io

When using crates from eg. crates.io, and also things like std and core

Vendoring your packages was very tedious to even remotely get to work with Cargo. I spent a very long time getting Cargo to work together with cargo-local-registry. We vendor crates from crates.io and a custom internal registry.

So this is my question: Which way was the right to find it out? There is no info about this feature on crates.io. I also have no clue what exactly it does and why it is named rwh_05.
