Rust has a fine-grained memory management, but it is automatically managed once created. Each variable has a scope in which it is valid, and it is automatically de-allocated when it goes out of scope.

The following code snippet shows an example of memory management:

fn main() {
      // 'Slot' is an *owned* value
      let slot = box 3i;// The Slot goes out of scope here, it is owner if its data
  }
