Required Methods

Get the object id.

This function returns the same value as as_native_vulkan_object(), but conveniently cast to a u64. This is useful for extensions like VK_EXT_debug_report and VK_EXT_debug_marker, which use these to refer Vulkan objects.

Object ids (or more correctly, handles) come in two variants, dispatchable and non-dispatchable. While dispatchable objects are actually pointers, and thus unique, the same is not true for non-dispatchable objects. For instance, two Semaphores, created independently of each other, might in fact have the same handle.

Additionally, handles of non-dispatchable objects are only ever meaningful, if their type is known (whether it is i.e. a Semaphore or some other type). This must be taken into account, if handles are used to identify Vulkan objects.

Refer to the Vulkan specification (Object Model) for more information.
