VkPhysicalDevice

Vulkan separates the concept of physical and logical devices. A physical device usually represents a single complete implementation of Vulkan (excluding instance-level functionality) available to the host, of which there are a finite number. A logical device represents an instance of that implementation with its own state and resources independent of other logical devices.

Physical devices cannot be independently destroyed, and are instead destroyed with the VkInstance that they were retrieved from.

Physical devices are represented by VkPhysicalDevice handles:

VK_DEFINE_HANDLE(VkPhysicalDevice)

#[repr(transparent)]
pub struct PhysicalDevice(_);
