Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

OpaqueFd = 1

A POSIX file descriptor handle that is only usable with Vulkan and compatible APIs.

§

OpaqueWin32 = 2

A Windows NT handle that is only usable with Vulkan and compatible APIs.

§

OpaqueWin32Kmt = 4

A Windows global share handle that is only usable with Vulkan and compatible APIs.

§

D3D11Texture = 8

A Windows NT handle that refers to a Direct3D 10 or 11 texture resource.

§

D3D11TextureKmt = 16

A Windows global share handle that refers to a Direct3D 10 or 11 texture resource.

§

D3D12Heap = 32

A Windows NT handle that refers to a Direct3D 12 heap resource.

§

D3D12Resource = 64

A Windows NT handle that refers to a Direct3D 12 committed resource.

§

DmaBuf = 512

A POSIX file descriptor handle that refers to a Linux dma-buf.

§

AndroidHardwareBuffer = 1_024

A handle for an Android AHardwareBuffer object.

§

HostAllocation = 128

A pointer to memory that was allocated by the host.

§

HostMappedForeignMemory = 256

A pointer to a memory mapping on the host that maps non-host memory.

§

ZirconVmo = 2_048

A Zircon handle to a virtual memory object.

§

RdmaAddress = 4_096

A Remote Direct Memory Address handle to an allocation that is accessible by remote devices.
