## Description

One of the states that contributes to the combinatorial explosion of pipeline state objects that need to be created, is the vertex input binding and attribute descriptions. By allowing them to be dynamic applications may reduce the number of pipeline objects they need to create.

This extension adds dynamic state support for what is normally static state in VkPipelineVertexInputStateCreateInfo.

## New Commands

- vkCmdSetVertexInputEXT

## New Structures

- VkVertexInputAttributeDescription2EXT

- VkVertexInputBindingDescription2EXT

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceVertexInputDynamicStateFeaturesEXT

## New Enum Constants

- `VK_EXT_VERTEX_INPUT_DYNAMIC_STATE_EXTENSION_NAME`

- `VK_EXT_VERTEX_INPUT_DYNAMIC_STATE_SPEC_VERSION`

- Extending VkDynamicState:

  - `VK_DYNAMIC_STATE_VERTEX_INPUT_EXT`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VERTEX_INPUT_DYNAMIC_STATE_FEATURES_EXT`

  - `VK_STRUCTURE_TYPE_VERTEX_INPUT_ATTRIBUTE_DESCRIPTION_2_EXT`

  - `VK_STRUCTURE_TYPE_VERTEX_INPUT_BINDING_DESCRIPTION_2_EXT`

## Version History

- Revision 2, 2020-11-05 (Piers Daniell)

  - Make VkVertexInputBindingDescription2EXT extensible

  - Add new VkVertexInputAttributeDescription2EXT struct for the `pVertexAttributeDescriptions` parameter to vkCmdSetVertexInputEXT so it is also extensible

- Revision 1, 2020-08-21 (Piers Daniell)

  - Internal revisions
