VkCopyDescriptorSet

The VkCopyDescriptorSet structure is defined as:

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;

• 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. If the descriptor binding identified by srcSet and srcBinding has a descriptor type of VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK then srcArrayElement specifies the starting byte offset within the binding to copy from.
• dstSet, dstBinding, and dstArrayElement are the destination set, binding, and array element, respectively. If the descriptor binding identified by dstSet and dstBinding has a descriptor type of VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK then dstArrayElement specifies the starting byte offset within the binding to copy to.
• 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. If the descriptor binding identified by srcSet and srcBinding has a descriptor type of VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK then descriptorCount specifies the number of bytes to copy and the remaining array elements in the source or destination binding refer to the remaining number of bytes in those.

If the VkDescriptorSetLayoutBinding for dstBinding is VK_DESCRIPTOR_TYPE_MUTABLE_EXT and srcBinding is not VK_DESCRIPTOR_TYPE_MUTABLE_EXT, the new active descriptor type becomes the descriptor type of srcBinding. If both VkDescriptorSetLayoutBinding for srcBinding and dstBinding are VK_DESCRIPTOR_TYPE_MUTABLE_EXT, the active descriptor type in each source descriptor is copied into the corresponding destination descriptor. The active descriptor type can be different for each source descriptor.
