Finally, there are various projects around QEMU that are being written in Rust (https://gitlab.com/virtio-fs/virtiofsd-rs, and a few other than are more experimental). https://github.com/nutanix/libvfio-user could really benefit from a native Rust implementation, once the protocol is stable. Then we can implement out of process devices in Rust too.
