C++ and Rust are very different. A direct binding is near impossible. This project takes a pragmatic approach: the GUI part is QML/Qt and the logic part is Rust. The separation is quite strict. The demo application showcases more of the features than the blog does. Notably, the mapping between the Qt data models and the Rust code is something that makes development effective. This will be emphasized in the upcoming FOSDEM presentation.
