Memory benchmarking?

Hello, I have some difficulties to find a benchmark tool for memory usage in Rust. Ideally I'm searching for a crate that is able to measure : memory usage CPU real time CPU elapsed time Note: I'm on Linux The fact that I don't find one is maybe due to a silly idea I have (?) Or maybe because the better way is to implement measure points by myself ? (doesn't seem complicated...) Open to your advice and suggestions.
