Tbf, you have to be pretty far with Rust to get to a point where Rust's compiler errors stop helping you (at least, as far as I've seen). After that, it's pretty much the same
Yep use a little bit more deeply cascaded generic rust code with a lot of fancy trait-bounds and error messages will explode and be similar as C++ (though to be fair they are still likely way more helpful than C++ template based error messages). Really hope that the compiler/error devs will improve in this area
This is actually unironically a major benefit of Rust - compile time errors are supposed to be for dev mistakes and runtime errors supposed to be for user mistakes. Way easier to debug something at compile time instead of runtime.
