How/when are underlying Vulkan objects destroyed?

[johan-overbye]

Say for example there are no more app-side references to my vulkano::device::Device, but I hold on to a vulkano::buffer::Buffer reference. Is it correct to assume that the VkDevice is still alive because the Buffer has an Arc<Device> somewhere?

If so, is there an idiomatic way to at least assert that my device is destroyed when I expect it to be? I guess I could try_unwrap the Arc<Device> maybe?

Yes, any object that belongs to Device will hold a reference to it and keep it alive. Using try_unwrap will work.
