In the end of rust-book I read told about user allocators support and that it uses some performance allocators when and where possible. I am curious, maybe rust also gathers some information about memory usage? Or in order to do this I need to implement my own allocators?

Is there a possibility to determine rust program memory usage?

I asked a similar question last year, and was pointed to heapsize.
