This structure describes the following features:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• EXTENSION FEATURES SHADERINPUTATTACHMENTARRAYDYNAMICINDEXING
  shaderInputAttachmentArrayDynamicIndexing indicates whether arrays of input attachments can be indexed by integer expressions that are dynamically uniform within either the subgroup or the invocation group in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_INPUT_ATTACHMENT must be indexed only by constant integral expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the InputAttachmentArrayDynamicIndexing capability.
• EXTENSION FEATURES SHADERUNIFORMTEXELBUFFERARRAYDYNAMICINDEXING
  shaderUniformTexelBufferArrayDynamicIndexing indicates whether arrays of uniform texel buffers can be indexed by integer expressions that are dynamically uniform within either the subgroup or the invocation group in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER must be indexed only by constant integral expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the UniformTexelBufferArrayDynamicIndexing capability.
• EXTENSION FEATURES SHADERSTORAGETEXELBUFFERARRAYDYNAMICINDEXING
  shaderStorageTexelBufferArrayDynamicIndexing indicates whether arrays of storage texel buffers can be indexed by integer expressions that are dynamically uniform within either the subgroup or the invocation group in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER must be indexed only by constant integral expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the StorageTexelBufferArrayDynamicIndexing capability.
• EXTENSION FEATURES SHADERUNIFORMBUFFERARRAYNONUNIFORMINDEXING
  shaderUniformBufferArrayNonUniformIndexing indicates whether arrays of uniform buffers can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER or VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the UniformBufferArrayNonUniformIndexing capability.
• EXTENSION FEATURES SHADERSAMPLEDIMAGEARRAYNONUNIFORMINDEXING
  shaderSampledImageArrayNonUniformIndexing indicates whether arrays of samplers or sampled images can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_SAMPLER, VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER, or VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the SampledImageArrayNonUniformIndexing capability.
• EXTENSION FEATURES SHADERSTORAGEBUFFERARRAYNONUNIFORMINDEXING
  shaderStorageBufferArrayNonUniformIndexing indicates whether arrays of storage buffers can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_STORAGE_BUFFER or VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the StorageBufferArrayNonUniformIndexing capability.
• EXTENSION FEATURES SHADERSTORAGEIMAGEARRAYNONUNIFORMINDEXING
  shaderStorageImageArrayNonUniformIndexing indicates whether arrays of storage images can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_STORAGE_IMAGE must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the StorageImageArrayNonUniformIndexing capability.
• EXTENSION FEATURES SHADERINPUTATTACHMENTARRAYNONUNIFORMINDEXING
  shaderInputAttachmentArrayNonUniformIndexing indicates whether arrays of input attachments can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_INPUT_ATTACHMENT must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the InputAttachmentArrayNonUniformIndexing capability.
• EXTENSION FEATURES SHADERUNIFORMTEXELBUFFERARRAYNONUNIFORMINDEXING
  shaderUniformTexelBufferArrayNonUniformIndexing indicates whether arrays of uniform texel buffers can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the UniformTexelBufferArrayNonUniformIndexing capability.
• EXTENSION FEATURES SHADERSTORAGETEXELBUFFERARRAYNONUNIFORMINDEXING
  shaderStorageTexelBufferArrayNonUniformIndexing indicates whether arrays of storage texel buffers can be indexed by non-uniform integer expressions in shader code. If this feature is not enabled, resources with a descriptor type of VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER must not be indexed by non-uniform integer expressions when aggregated into arrays in shader code. This also indicates whether shader modules can declare the StorageTexelBufferArrayNonUniformIndexing capability.
• EXTENSION FEATURES DESCRIPTORBINDINGUNIFORMBUFFERUPDATEAFTERBIND
  descriptorBindingUniformBufferUpdateAfterBind indicates whether the implementation supports updating uniform buffer descriptors after a set is bound. If this feature is not enabled, VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT must not be used with VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER.
• EXTENSION FEATURES DESCRIPTORBINDINGSAMPLEDIMAGEUPDATEAFTERBIND
  descriptorBindingSampledImageUpdateAfterBind indicates whether the implementation supports updating sampled image descriptors after a set is bound. If this feature is not enabled, VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT must not be used with VK_DESCRIPTOR_TYPE_SAMPLER, VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER, or VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE.
• EXTENSION FEATURES DESCRIPTORBINDINGSTORAGEIMAGEUPDATEAFTERBIND
  descriptorBindingStorageImageUpdateAfterBind indicates whether the implementation supports updating storage image descriptors after a set is bound. If this feature is not enabled, VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT must not be used with VK_DESCRIPTOR_TYPE_STORAGE_IMAGE.
• EXTENSION FEATURES DESCRIPTORBINDINGSTORAGEBUFFERUPDATEAFTERBIND
  descriptorBindingStorageBufferUpdateAfterBind indicates whether the implementation supports updating storage buffer descriptors after a set is bound. If this feature is not enabled, VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT must not be used with VK_DESCRIPTOR_TYPE_STORAGE_BUFFER.
• EXTENSION FEATURES DESCRIPTORBINDINGUNIFORMTEXELBUFFERUPDATEAFTERBIND
  descriptorBindingUniformTexelBufferUpdateAfterBind indicates whether the implementation supports updating uniform texel buffer descriptors after a set is bound. If this feature is not enabled, VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT must not be used with VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER.

If this feature is not enabled, VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT must not be used with VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER.
• EXTENSION FEATURES DESCRIPTORBINDINGUPDATEUNUSEDWHILEPENDING
  descriptorBindingUpdateUnusedWhilePending indicates whether the implementation supports updating descriptors while the set is in use. If this feature is not enabled, VK_DESCRIPTOR_BINDING_UPDATE_UNUSED_WHILE_PENDING_BIT must not be used.
• EXTENSION FEATURES DESCRIPTORBINDINGPARTIALLYBOUND
  descriptorBindingPartiallyBound indicates whether the implementation supports statically using a descriptor set binding in which some descriptors are not valid. If this feature is not enabled, VK_DESCRIPTOR_BINDING_PARTIALLY_BOUND_BIT must not be used.

  descriptorBindingVariableDescriptorCount indicates whether the implementation supports descriptor sets with a variable-sized last binding. If this feature is not enabled, VK_DESCRIPTOR_BINDING_VARIABLE_DESCRIPTOR_COUNT_BIT must not be used.
• EXTENSION FEATURES RUNTIMEDESCRIPTORARRAY
  runtimeDescriptorArray indicates whether the implementation supports the SPIR-V RuntimeDescriptorArray capability. If this feature is not enabled, descriptors must not be declared in runtime arrays.

If the VkPhysicalDeviceDescriptorIndexingFeatures structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceDescriptorIndexingFeatures, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
