/**
* Structure specifying a specialization map entry.
*
* Description
*
* If a {@code constantID} value is not a specialization constant ID used in the shader, that map entry does not affect the behavior of the pipeline.
*
* Valid Usage
*
*
* - For a {@code constantID} specialization constant declared in a shader, {@code size} must match the byte size of the {@code constantID}. If the specialization constant is of type {@code boolean}, {@code size} must be the byte size of {@code VkBool32}
*
*
* See Also
*
* {@link VkSpecializationInfo}
*
* Member documentation
*
*
* - {@code constantID} – the ID of the specialization constant in SPIR-V.
* - {@code offset} – the byte offset of the specialization constant value within the supplied data buffer.
* - {@code size} – the byte size of the specialization constant value within the supplied data buffer.
*
*
* Layout
*
* struct VkSpecializationMapEntry {
uint32_t constantID;
uint32_t offset;
size_t size;
}
