Structure specifying a copy descriptor set operation.

Description

If the VkDescriptorSetLayoutBinding for dstBinding is DESCRIPTOR_TYPE_MUTABLE_EXT and srcBinding is not DESCRIPTOR_TYPE_MUTABLE_EXT, the new active descriptor type becomes the descriptor type of srcBinding. If both VkDescriptorSetLayoutBinding for srcBinding and dstBinding are 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.

Valid Usage

• srcBinding must be a valid binding within srcSet
• 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, as described by consecutive binding updates
• dstBinding must be a valid binding within dstSet
• 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, as described by consecutive binding updates
• The type of dstBinding within dstSet must be equal to the type of srcBinding within srcSet
• 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 as described by consecutive binding updates
• If the descriptor type of the descriptor set binding specified by srcBinding is DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK, srcArrayElement must be an integer multiple of 4
• If the descriptor type of the descriptor set binding specified by dstBinding is DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK, dstArrayElement must be an integer multiple of 4
• If the descriptor type of the descriptor set binding specified by either srcBinding or dstBinding is DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK, descriptorCount must be an integer multiple of 4
• If srcSet’s layout was created with the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT flag set, then dstSet’s layout must also have been created with the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT flag set
• If srcSet’s layout was created with neither DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT nor DESCRIPTOR_SET_LAYOUT_CREATE_HOST_ONLY_POOL_BIT_EXT flags set, then dstSet’s layout must have been created without the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT flag set
• If the descriptor pool from which srcSet was allocated was created with the 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 DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT flag set
• If the descriptor pool from which srcSet was allocated was created with neither DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT nor DESCRIPTOR_POOL_CREATE_HOST_ONLY_BIT_EXT flags set, then the descriptor pool from which dstSet was allocated must have been created without the DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT flag set
• If the descriptor type of the descriptor set binding specified by dstBinding is DESCRIPTOR_TYPE_SAMPLER, then dstSet must not have been allocated with a layout that included immutable samplers for dstBinding
• If VkDescriptorSetLayoutBinding for dstSet at dstBinding is DESCRIPTOR_TYPE_MUTABLE_EXT, the new active descriptor type must exist in the corresponding pMutableDescriptorTypeLists list for dstBinding if the new active descriptor type is not DESCRIPTOR_TYPE_MUTABLE_EXT
• If VkDescriptorSetLayoutBinding for srcSet at srcBinding is DESCRIPTOR_TYPE_MUTABLE_EXT and the VkDescriptorSetLayoutBinding for dstSet at dstBinding is not DESCRIPTOR_TYPE_MUTABLE_EXT, the active descriptor type for the source descriptor must match the descriptor type of dstBinding
• If VkDescriptorSetLayoutBinding for dstSet at dstBinding is DESCRIPTOR_TYPE_MUTABLE_EXT, and the new active descriptor type is DESCRIPTOR_TYPE_MUTABLE_EXT, the pMutableDescriptorTypeLists for srcBinding and dstBinding must match exactly

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_COPY_DESCRIPTOR_SET
• pNext must be NULL
• srcSet must be a valid VkDescriptorSet handle
• dstSet must be a valid VkDescriptorSet handle
• Both of dstSet, and srcSet must have been created, allocated, or retrieved from the same VkDevice
