vkGetShaderModuleCreateInfoIdentifierEXT

VkShaderModuleCreateInfo structures have unique identifiers associated with them. To query an implementation provided identifier, call:

void vkGetShaderModuleCreateInfoIdentifierEXT(
    VkDevice device,
    const VkShaderModuleCreateInfo* pCreateInfo,
    VkShaderModuleIdentifierEXT* pIdentifier);

• device is the logical device that can create a VkShaderModule from pCreateInfo.
• pCreateInfo is a pointer to a VkShaderModuleCreateInfo structure.
• pIdentifier is a pointer to the returned VkShaderModuleIdentifierEXT.

The identifier returned by implementation must only depend on shaderIdentifierAlgorithmUUID and information provided in the VkShaderModuleCreateInfo. The implementation may return equal identifiers for two different VkShaderModuleCreateInfo structures if the difference does not affect pipeline compilation. Identifiers are only meaningful on different VkDevice objects if the device the identifier was queried from had the same shaderModuleIdentifierAlgorithmUUID as the device consuming the identifier.

The identifier returned by the implementation in vkGetShaderModuleCreateInfoIdentifierEXT must be equal to the identifier returned by vkGetShaderModuleIdentifierEXT given equivalent definitions of VkShaderModuleCreateInfo and any chained pNext structures.
