Comment (by nickm):

 Replying to [comment:14 chelseakomlo]:
 > How likely is it that this functionality (or parts of it) can be
 implemented in Rust? Would it require a lot of refactoring or is it
 already fairly modularized?

 It's not so well modularized right now.  The big problem here is that the
 code is written with the assjumption that relay crypto finishes
 immediately, but with this change, we'd sometimes have to wait on another
 thread before we had cells to send on a given circuit.
