This is an open chance to discuss how to integrate Rust into QEMU. I don't think this proposal really triggers that discussion to any great extent, because 'simpletrace.py' is not a part of the QEMU codebase in any meaningul way. It is a standalone python script that just happens to live in the qemu.git repository. The difficult questions around Rust integration will arise when we want to have Rust used to /replace/ some existing non-optional functionality. IOW, if Rust were to become a mandatory dep of QEMU that could not be avoided. In fact I kinda wonder whether this Rust simpletrace code could simply be its own git repo under gitlab.com/qemu-project/...., rather than put into the monolithic QEMU repo ? That just makes it a "normal" Rust project and no questions around integration with QEMU's traditional build system would arise.
