I’ll say that when I started working on finl a couple years ago, I started in C++ (employing 20+-year-old memories of the language). When I switched to Rust, starting from zero, I found myself instantly productive. Yes, there are some things that are harder, but in general, the if it compiles, it works rule holds for Rust. I can still remember some rather disturbing bugs that should never have even compiled in some of my early C code (e.g., treating argv values as if they were variables and could be modified in place).
