C Specification

VkShaderModuleIdentifierEXT represents a shader module identifier returned by the implementation.

// Provided by VK_EXT_shader_module_identifier
typedef struct VkShaderModuleIdentifierEXT {
    VkStructureType    sType;
    void*              pNext;
    uint32_t           identifierSize;
    uint8_t            identifier[VK_MAX_SHADER_MODULE_IDENTIFIER_SIZE_EXT];
} VkShaderModuleIdentifierEXT;

Members

  • sType is the type of this structure.

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

  • identifierSize is the size, in bytes, of valid data returned in identifier.

  • identifier is a buffer of opaque data specifying an identifier.

Description

Any returned values beyond the first identifierSize bytes are undefined. Implementations must return an identifierSize greater than 0, and less-or-equal to VK_MAX_SHADER_MODULE_IDENTIFIER_SIZE_EXT.

Two identifiers are considered equal if identifierSize is equal and the first identifierSize bytes of identifier compare equal.

Implementations may return a different identifierSize for different modules. Implementations should ensure that identifierSize is large enough to uniquely define a shader module.

Valid Usage (Implicit)
  • VUID-VkShaderModuleIdentifierEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_SHADER_MODULE_IDENTIFIER_EXT

  • VUID-VkShaderModuleIdentifierEXT-pNext-pNext
    pNext must be NULL
