Resource access flags for resource barriers.

Note

Translates to DirectX 12 as D3D12_BARRIER_ACCESS, Vulkan as VkAccessFlags2.

Values:

• WisResourceAccessCommon = 0: Common access.
• WisResourceAccessVertexBuffer = (1 << 0): Vertex buffer access. Applies only to buffers.
• WisResourceAccessConstantBuffer = (1 << 1): Constant buffer access. Applies only to buffers.
• WisResourceAccessIndexBuffer = (1 << 2): Index buffer access. Applies only to buffers.
• WisResourceAccessRenderTarget = (1 << 3): Render target access. Applies only to textures.
• WisResourceAccessUnorderedAccess = (1 << 4): Unordered access.
• WisResourceAccessDepthWrite = (1 << 5): Depth write access. Applies only to depth-stencil textures.
• WisResourceAccessDepthRead = (1 << 6): Depth read access. Applies only to depth-stencil textures.
• WisResourceAccessShaderResource = (1 << 7): Shader resource access.
• WisResourceAccessStreamOutput = (1 << 8): Stream output access. Applies only to buffers.
• WisResourceAccessIndirectArgument = (1 << 9): Indirect argument access.
• WisResourceAccessCopyDst = (1 << 10): Copy destination access.
• WisResourceAccessCopySrc = (1 << 11): Copy source access.
• WisResourceAccessConditionalRendering = (1 << 12): Conditional rendering access.
• WisResourceAccessAccelerationStructureRead = (1 << 13): Acceleration structure read access.
• WisResourceAccessAccelerationStructureWrite = (1 << 14): Acceleration structure write access.
• WisResourceAccessShadingRate = (1 << 15): Shading rate access.
• WisResourceAccessVideoDecodeRead = (1 << 16): Video decode read access.
• WisResourceAccessVideoDecodeWrite = (1 << 17): Video decode write access.
• WisResourceAccessResolveDst = (1 << 18): Resolve destination access.
• WisResourceAccessResolveSrc = (1 << 19): Resolve source access.
• WisResourceAccessNone = (1 << 31): No access. Used to indicate no access throughout the pipeline.
