We are Rust noobs :-). The Python utilities are random tools and daemons, so it's been a nice experience getting my feet wet in a completely different paradigm with rustc.

So the biggest challenge with moving to another language is reproducing the same low latency and high performance we've carefully designed in C++ to a Rust analogue... which given we haven't really used Rust enough yet to have a total sense of this, is hard.

In the long future, I can see Rust working in gradual stages -- but of course focusing on biz objectives is better first when we know how to write high perf C++, hence spending time to play with Rust on side tooling or other smaller projects.

From what little Rust I've written so far I really do like it, so hoping that I can incorporate it more
