VkIndirectCommandsIndexBufferTokenEXT

The VkIndirectCommandsIndexBufferTokenEXT structure specifies the layout token info for the VK_INDIRECT_COMMANDS_TOKEN_TYPE_INDEX_BUFFER_EXT token.

typedef struct VkIndirectCommandsIndexBufferTokenEXT {
    VkIndirectCommandsInputModeFlagBitsEXT mode;
} VkIndirectCommandsIndexBufferTokenEXT;

• mode specifies the mode to use with this token.

This allows for easy layering of Vulkan atop other APIs. When VK_INDIRECT_COMMANDS_INPUT_MODE_DXGI_INDEX_BUFFER_EXT is specified, the indirect buffer can contain a D3D12_INDEX_BUFFER_VIEW instead of VkBindIndexBufferIndirectCommandEXT as D3D’s DXGI format value is mapped to the VkIndexType. It works as both structs are otherwise binary compatible.
