QEMU is pretty low-level, so I'm not sure other languages will fit the bill as
good, and for the parts relevant to QEMU you have just as much control of
low-level details as with C (having a very close syntax also helps

But I'm curious, what'd be the advantage of rust? Cross-language bindings are
usually expensive, and require some duplication for defining structures across
them (maybe it's not the case for rust).
