The binding generator generates a binding from a JSON file. That gives C++ and Rust code. Additionally, a default Rust implementation is generated for convenience where the programmer fills in the application logic.
At no point is there a need to edit a generated C++ file. Any other build tool with C++ support could be used instead of CMake. What it should do is call rust_qt_binding_generator when the binding description changes.
