How does Rust's memory management compare to that of C?
There are two cases two consider: Rust using std library Rust without std lib. In the first case, Rust assumes you have some runtime that provides memory management (and other features), usually in the form of operating system.This makes programming much easier, but comes with assumption that you have enough memory, and if you dont, the program will panic. In the second case, Rust has nothing to work with, so you have to manage memory yourself. This makes it similar to any other language that runs on bare metal. Any resource in Rust always has an owner. You can use reference counting (Rc or Arc types) if the ownership should be shared, but its opt-in. One difference is when it comes to freeing memory. Rust compiler tracks ownership, so it knows when something is not needed anymore, and inserts calls to destructors (in the form of Drop trait) automatically, so you dont have to worry about that.
