IME, it's become very usable for user-space code. Bare metal still pretty much 
requires unstable features, but that's not a problem for FFmpeg.

We may want to depend on the allocator_api unstable feature for fallible 
allocations (or just allow non-fallible allocations in Rust code until that 
gets stabilised). Naked functions would be nice for assembler, but I don't 
think that we have any urgent need to call assembler from Rust (as opposed to 
from C).

Yikes. Rust is actually way saner for type-generic programming than C++.
