C Specification

An identifier can be provided instead of shader code in an attempt to compile pipelines without providing complete SPIR-V to the implementation.

The VkPipelineShaderStageModuleIdentifierCreateInfoEXT structure is defined as:

// Provided by VK_EXT_shader_module_identifier
typedef struct VkPipelineShaderStageModuleIdentifierCreateInfoEXT {
    VkStructureType    sType;
    const void*        pNext;
    uint32_t           identifierSize;
    const uint8_t*     pIdentifier;
} VkPipelineShaderStageModuleIdentifierCreateInfoEXT;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • identifierSize is the size, in bytes, of the buffer pointed to by pIdentifier.

  • pIdentifier is a pointer to a buffer of opaque data specifying an identifier.

Description

Any identifier can be used. If the pipeline being created with identifier requires compilation to complete the pipeline creation call, pipeline compilation must fail as defined by VK_PIPELINE_CREATE_FAIL_ON_PIPELINE_COMPILE_REQUIRED_BIT.

pIdentifier and identifierSize can be obtained from an VkShaderModuleIdentifierEXT queried earlier.
