rust armanazi mem deallocating

To deallocate memory in Rust, you can use the drop function or let the variable go out of scope.

The drop function is called explicitly when you want to deallocate memory. You can use it to explicitly destroy an object and free its associated resources. Here's an example:

struct MyStruct {
    // Some fields
}

impl Drop for MyStruct {
    fn drop(&mut self) {
        // Clean up resources here
    }
}

fn main() {
    let my_struct = MyStruct {
        // Initialize the struct
    };

    // Use my_struct

    drop(my_struct); // Explicitly call drop to deallocate memory
}

In this example, the drop function is called on my_struct to explicitly deallocate its memory.

Alternatively, you can let a variable go out of scope to automatically deallocate its memory. Here's an example:

fn main() {
    {
        let my_struct = MyStruct {
            // Initialize the struct
        };

        // Use my_struct
    }
    // Memory for my_struct is automatically deallocated when it goes out of scope
}

In this case, when the inner block ends, the variable my_struct goes out of scope and its memory is automatically deallocated.

Both methods, either using drop or letting a variable go out of scope, allow you to deallocate memory in Rust.
