C Specification

The list of potential descriptor types a given mutable descriptor can mutate to is passed in a VkMutableDescriptorTypeListEXT structure.

The VkMutableDescriptorTypeListEXT structure is defined as:

// Provided by VK_EXT_mutable_descriptor_type
typedef struct VkMutableDescriptorTypeListEXT {
    uint32_t                   descriptorTypeCount;
    const VkDescriptorType*    pDescriptorTypes;
} VkMutableDescriptorTypeListEXT;

or the equivalent

// Provided by VK_VALVE_mutable_descriptor_type
typedef VkMutableDescriptorTypeListEXT VkMutableDescriptorTypeListVALVE;

Members

  • descriptorTypeCount is the number of elements in pDescriptorTypes.

  • pDescriptorTypes is NULL or a pointer to an array of descriptorTypeCount VkDescriptorType values defining which descriptor types a given binding may mutate to.

Description

Valid Usage

  • VUID-VkMutableDescriptorTypeListEXT-descriptorTypeCount-04597
    descriptorTypeCount must not be 0 if the corresponding binding is of VK_DESCRIPTOR_TYPE_MUTABLE_EXT

  • VUID-VkMutableDescriptorTypeListEXT-pDescriptorTypes-04598
    pDescriptorTypes must be a valid pointer to an array of descriptorTypeCount valid, unique VkDescriptorType values if the given binding is of VK_DESCRIPTOR_TYPE_MUTABLE_EXT type

  • VUID-VkMutableDescriptorTypeListEXT-descriptorTypeCount-04599
    descriptorTypeCount must be 0 if the corresponding binding is not of VK_DESCRIPTOR_TYPE_MUTABLE_EXT

  • VUID-VkMutableDescriptorTypeListEXT-pDescriptorTypes-04600
    pDescriptorTypes must not contain VK_DESCRIPTOR_TYPE_MUTABLE_EXT

  • VUID-VkMutableDescriptorTypeListEXT-pDescriptorTypes-04601
    pDescriptorTypes must not contain VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC

  • VUID-VkMutableDescriptorTypeListEXT-pDescriptorTypes-04602
    pDescriptorTypes must not contain VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC

  • VUID-VkMutableDescriptorTypeListEXT-pDescriptorTypes-04603
    pDescriptorTypes must not contain VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK

Valid Usage (Implicit)

  • VUID-VkMutableDescriptorTypeListEXT-pDescriptorTypes-parameter
    If descriptorTypeCount is not 0, pDescriptorTypes must be a valid pointer to an array of descriptorTypeCount valid VkDescriptorType values
