Should I develop my project in Rust or continue with C++?

I've only done high level stuff until now. Never got to the low level stuff but now I might have to because my project is going to be a circuit simulation software so it will require a fast language.

I've tried setting up my project using C++ but its a complete mess. Too many errors with editors, cmake doesnt work as intended and I'm just finding it too complex to work with it now.

Should I switch to rust? I don't know rust yet so I have to learn it from scratch and I'm expecting stuff like cargo or crate to make things easier for me.
