C Specification

The VkCopyDescriptorSet structure is defined as:

// Provided by VK_VERSION_1_0
typedef struct VkCopyDescriptorSet {
    VkStructureType    sType;
    const void*        pNext;
    VkDescriptorSet    srcSet;
    uint32_t           srcBinding;
    uint32_t           srcArrayElement;
    VkDescriptorSet    dstSet;
    uint32_t           dstBinding;
    uint32_t           dstArrayElement;
    uint32_t           descriptorCount;
} VkCopyDescriptorSet;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • srcSet, srcBinding, and srcArrayElement are the source set, binding, and array element, respectively.

  • dstSet, dstBinding, and dstArrayElement are the destination set, binding, and array element, respectively.

  • descriptorCount is the number of descriptors to copy from the source to destination. If descriptorCount is greater than the number of remaining array elements in the source or destination binding, those affect consecutive bindings in a manner similar to VkWriteDescriptorSet above.

Description

Valid Usage

  • VUID-VkCopyDescriptorSet-srcBinding-00345
    srcBinding must be a valid binding within srcSet

  • VUID-VkCopyDescriptorSet-srcArrayElement-00346
    The sum of srcArrayElement and descriptorCount must be less than or equal to the number of array elements in the descriptor set binding specified by srcBinding, and all applicable consecutive bindings

  • VUID-VkCopyDescriptorSet-dstBinding-00347
    dstBinding must be a valid binding within dstSet

  • VUID-VkCopyDescriptorSet-dstArrayElement-00348
    The sum of dstArrayElement and descriptorCount must be less than or equal to the number of array elements in the descriptor set binding specified by dstBinding, and all applicable consecutive bindings

  • VUID-VkCopyDescriptorSet-dstBinding-02632
    The type of dstBinding within dstSet must be equal to the type of srcBinding within srcSet

  • VUID-VkCopyDescriptorSet-srcSet-00349
    If srcSet is equal to dstSet, then the source and destination ranges of descriptors must not overlap, where the ranges may include array elements from consecutive bindings

  • VUID-VkCopyDescriptorSet-srcSet-01918
    If srcSet’s layout was created with the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT flag set, then dstSet’s layout must also have been created with the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT flag set

  • VUID-VkCopyDescriptorSet-srcSet-04885
    If srcSet’s layout was created without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT flag set, then dstSet’s layout must have been created without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT flag set

  • VUID-VkCopyDescriptorSet-srcSet-01920
    If the descriptor pool from which srcSet was allocated was created with the VK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT flag set, then the descriptor pool from which dstSet was allocated must also have been created with the VK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT flag set

  • VUID-VkCopyDescriptorSet-srcSet-04887
    If the descriptor pool from which srcSet was allocated was created without the VK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT flag set, then the descriptor pool from which dstSet was allocated must have been created without the VK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT flag set

  • VUID-VkCopyDescriptorSet-dstBinding-02753
    If the descriptor type of the descriptor set binding specified by dstBinding is VK_DESCRIPTOR_TYPE_SAMPLER, then dstSet must not have been allocated with a layout that included immutable samplers for dstBinding

Valid Usage (Implicit)

  • VUID-VkCopyDescriptorSet-sType-sType
    sType must be VK_STRUCTURE_TYPE_COPY_DESCRIPTOR_SET

  • VUID-VkCopyDescriptorSet-pNext-pNext
    pNext must be NULL

  • VUID-VkCopyDescriptorSet-srcSet-parameter
    srcSet must be a valid VkDescriptorSet handle

  • VUID-VkCopyDescriptorSet-dstSet-parameter
    dstSet must be a valid VkDescriptorSet handle

  • VUID-VkCopyDescriptorSet-commonparent
    Both of dstSet, and srcSet must have been created, allocated, or retrieved from the same VkDevice
