C++ Rust and Qt Easier than you think
summary
Shows concrete glue paths: using CXX or cbindgen to expose Rust types to C++, or KDAB’s CXX-Qt to write QML-first apps entirely in Rust; Corrosion automates invoking Cargo from CMake so Rust crates build inside a Qt project; real examples include a full Rust QML contrast app and Servo integrated via FFI. Remaining practical hurdles are packaging, Cargo vs CMake workflows, and static vs dynamic linking for distributions.
