I’m currently working on optimizing a big Rust project. I’m very new to Rust so I don’t know much about how to optimize. I saw in a Cherno video that there was a tool in Visual Studio C++ to see CPU usage per line of code, and I am wondering if there is a similar thing for VSCode Rust.

As @Chayim Friedman mentioned, this is called a profiler. The Rust Performance book has a non-exhaustive list of profilers that work with Rust, as you can see here. Cachegrind and Callgrind seem to be closest to what you wish to achieve
