VkShaderModuleIdentifierEXT

VkShaderModuleIdentifierEXT represents a shader module identifier returned by the implementation.

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

• 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 valid data returned in identifier.
• identifier is a buffer of opaque data specifying an identifier.

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.
