Hmm.. there are multiple old/new drivers (not a complete list) already
in Rust:
* NVME: https://rust-for-linux.com/nvme-driver
* binder: https://rust-for-linux.com/android-binder-driver
* Puzzlefs: https://rust-for-linux.com/puzzlefs-filesystem-driver
* Apple AGX GPU driver: https://rust-for-linux.com/apple-agx-gpu-driver
, so is there still a question that drivers can be written in Rust?
