C Specification

Information about the descriptor set layout is passed in an instance of the VkDescriptorSetLayoutCreateInfo structure:

typedef struct VkDescriptorSetLayoutCreateInfo {
    VkStructureType                        sType;
    const void*                            pNext;
    VkDescriptorSetLayoutCreateFlags       flags;
    uint32_t                               bindingCount;
    const VkDescriptorSetLayoutBinding*    pBindings;
} VkDescriptorSetLayoutCreateInfo;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • flags is a bitmask of VkDescriptorSetLayoutCreateFlagBits specifying options for descriptor set layout creation.

  • bindingCount is the number of elements in pBindings.

  • pBindings is a pointer to an array of VkDescriptorSetLayoutBinding structures.

Description

Valid Usage
  • The VkDescriptorSetLayoutBinding::binding members of the elements of the pBindings array must each have different values.

  • If flags contains VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT_KHR, then all elements of pBindings must not have a descriptorType of VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC or VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC

  • If flags contains VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT_KHR, then the total number of elements of all bindings must be less than or equal to VkPhysicalDevicePushDescriptorPropertiesKHR::maxPushDescriptors

  • If any binding has the VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT bit set, flags must include VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT_EXT

  • If any binding has the VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT bit set, then all bindings must not have descriptorType of VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC or VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC
