Right. I attempted using Rust for trading-related code as well. However, I failed to write a dynamically linked always sorted order book where you can splice orders in the middle. It is just too dynamic for Rust. Borrow checker killed me.
And don't get me started on dynamic graphs.
I would happily use Rust over C++ if it had all other improvements but similar memory management. I am completely unproductive with Rust model.
