## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `flags` is a bitmask of VkShaderCreateFlagBitsEXT describing additional parameters of the shader.

- `stage` is a VkShaderStageFlagBits value specifying a single shader stage.

- `nextStage` is a bitmask of VkShaderStageFlagBits specifying which stages can be used as a logically next bound stage when drawing with the shader bound. A value of zero indicates this shader stage must be the last one.

- `codeType` is a VkShaderCodeTypeEXT value specifying the type of the shader code pointed to be `pCode`.

- `codeSize` is the size in bytes of the shader code pointed to be `pCode`.

- `pCode` is a pointer to the shader code to use to create the shader.

- `pName` is a pointer to a null-terminated UTF-8 string specifying the entry point name of the shader for this stage.

- `setLayoutCount` is the number of descriptor set layouts pointed to by `pSetLayouts`.

- `pSetLayouts` is a pointer to an array of VkDescriptorSetLayout objects used by the shader stage. The implementation must not access these objects outside of the duration of the command this structure is passed to.

- `pushConstantRangeCount` is the number of push constant ranges pointed to by `pPushConstantRanges`.

- `pPushConstantRanges` is a pointer to an array of VkPushConstantRange structures used by the shader stage.

- `pSpecializationInfo` is a pointer to a VkSpecializationInfo structure, as described in Specialization Constants, or `NULL`.

## Description

When determining pipeline layout compatibility, compatibility is determined as if a the shader was created with a pipeline layout object that was created with identical values of `setLayoutCount`, `pSetLayouts`, `pushConstantRangeCount`, and `pPushConstantRanges`, and with VkPipelineLayoutCreateInfo::`flags` set to 0. If `flags` includes VK_SHADER_CREATE_DESCRIPTOR_HEAP_BIT_EXT, the shader is not considered created with a pipeline layout.

When specifying descriptor heap mappings, only mappings corresponding to bindings that are actually present in the SPIR-V shader affect compilation. Mappings are ignored when `codeType` is VK_SHADER_CODE_TYPE_BINARY_EXT. The resulting compiled binary from two different SPIR-V shaders which would have identical bit patterns must remain identical even if the mapping entries vary in any of the following ways:

- Different numbers of unused mapping structures

- Different binding counts for unused bindings

- Unused parameters in mapping structures (e.g. sampler offsets)

- Ignored parameters in mapping structures

- Different order of mapping structures, used or unused

Note | Calculating the same offset in a mapping via different parameter values is not guaranteed to provide identical results.
