Khronos Reference Page
Vulkan Specification
Contains information about specialization constants.

Specialization constants are a mechanism whereby constants in a SPIR-V module can have their constant value specified at the time the VkPipeline is created. This allows a SPIR-V module to have constants that can be modified while executing an application that uses the Vulkan API.

Valid Usage
- If mapEntryCount is not 0, pMapEntries must be a pointer to an array of mapEntryCount VkSpecializationMapEntry structures
- If dataSize is not 0, pData must be a pointer to an array of dataSize bytes
- The offset member of any given element of pMapEntries must be less than dataSize
- For any given element of pMapEntries, size must be less than or equal to dataSize minus offset
Member documentation
- mapEntryCount – the number of entries in the pMapEntries array
- pMapEntries – a pointer to an array of VkSpecializationMapEntry which maps constant IDs to offsets in pData
- dataSize – the byte size of the pData buffer
- pData – contains the actual constant values to specialize with
Layout
```
struct VkSpecializationInfo {
    uint32_t mapEntryCount;
    const VkSpecializationMapEntry * pMapEntries;
    size_t dataSize;
    const void * pData;
}
```
