Validity of memory area after `std::mem::forget`

help
7

I just looked into ManuallyDrop. Thanks for the hint. I think I will go for this one, as it also doesn't automatically dereference T if T is &T like mem::forget does.

Edit for the solution:

fn do_something<T> (data: T) {
    // Expose address of data here to device

    // After this call, data will NOT be cleaned up.
    // Memory must be cleaned up manually.
    ManuallyDrop::new(data);
}

This should work fine even when Tis of type &T.
