CXX-Qt is a set of Rust crates for creating bidirectional Rust ⇄ C++ bindings with Qt. It supports integrating Rust into C++ applications using CMake or building Rust applications with Cargo. CXX-Qt provides tools for implementing QObject subclasses in Rust that can be used from C++, QML, and JavaScript.
For 0.7, we have stabilized the cxx-qt bridge macro API and there have been many internal refactors to ensure that we have a consistent baseline to support going forward. We encourage developers to reach out if they find any unclear areas or missing features, to help us ensure a roadmap for them, as this may be the final time we can adapt the API. In the next releases, we’re looking towards stabilizing the cxx-qt-build and getting the cxx-qt-lib APIs ready for 1.0.

I’m a rust & qt neophyte: is kde now rust?
You could use this crate to build a Rust program which uses the Qt GUI framework and therefore would feel rather ‘native’ in KDE.
But the vast majority of KDE applications continue to be implemented in C++.
