## C Specification

The `VkDataGraphPipelineSingleNodeCreateInfoARM` structure is defined as:

    // Provided by VK_ARM_data_graph_optical_flow
    typedef struct VkDataGraphPipelineSingleNodeCreateInfoARM {
        VkStructureType                                      sType;
        void*                                                pNext;
        VkDataGraphPipelineNodeTypeARM                       nodeType;
        uint32_t                                             connectionCount;
        const VkDataGraphPipelineSingleNodeConnectionARM*    pConnections;
    } VkDataGraphPipelineSingleNodeCreateInfoARM;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `nodeType` is a VkDataGraphPipelineNodeTypeARM describing the type of this node.

- `connectionCount` is the length of the `pConnections` array.

- `pConnections` is a pointer to an array of `connectionCount` VkDataGraphPipelineSingleNodeConnectionARM structures.

## Description

Valid Usage

- VUID-VkDataGraphPipelineSingleNodeCreateInfoARM-nodeType-09963
  If `nodeType` is VK_DATA_GRAPH_PIPELINE_NODE_TYPE_OPTICAL_FLOW_ARM, then a VkDataGraphPipelineOpticalFlowCreateInfoARM structure must be included in the `pNext` chain of this structure

- VUID-VkDataGraphPipelineSingleNodeCreateInfoARM-nodeType-09978
  If `nodeType` is VK_DATA_GRAPH_PIPELINE_NODE_TYPE_OPTICAL_FLOW_ARM, then one and only VkDataGraphPipelineSingleNodeConnectionARM structure must be present in the `pConnections` array for each of the following values of its `connection` member:

  - VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_INPUT_ARM

  - VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_REFERENCE_ARM

  - VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_FLOW_VECTOR_ARM

- VUID-VkDataGraphPipelineSingleNodeCreateInfoARM-nodeType-09979
  If `nodeType` is VK_DATA_GRAPH_PIPELINE_NODE_TYPE_OPTICAL_FLOW_ARM and VkDataGraphPipelineOpticalFlowCreateInfoARM::`hintGridSize` is not 0, then one and only VkDataGraphPipelineSingleNodeConnectionARM structure whose `connection` member is VK_DATA_GRAPH_PIPELINE_NODE_CONNECTION_TYPE_OPTICAL_FLOW_HINT_ARM must be present in the `pConnections` array

Valid Usage (Implicit)

- VUID-VkDataGraphPipelineSingleNodeCreateInfoARM-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_DATA_GRAPH_PIPELINE_SINGLE_NODE_CREATE_INFO_ARM

- VUID-VkDataGraphPipelineSingleNodeCreateInfoARM-nodeType-parameter
  `nodeType` must be a valid VkDataGraphPipelineNodeTypeARM value

- VUID-VkDataGraphPipelineSingleNodeCreateInfoARM-pConnections-parameter
  `pConnections` must be a valid pointer to an array of `connectionCount` valid VkDataGraphPipelineSingleNodeConnectionARM structures

- VUID-VkDataGraphPipelineSingleNodeCreateInfoARM-connectionCount-arraylength
  `connectionCount` must be greater than `0`
