- layerName[VK_MAX_EXTENSION_NAME_SIZE] – a null-terminated UTF-8 string specifying the name of the layer. Use this name in the ppEnabledLayerNames array passed in the VkInstanceCreateInfo structure to enable this layer for an instance.
- specVersion – the Vulkan version the layer was written to, encoded as described in Version Numbers.
- implementationVersion – the version of this layer. It is an integer, increasing with backward compatible changes.
- description[VK_MAX_DESCRIPTION_SIZE] – a null-terminated UTF-8 string providing additional details that can be used by the application to identify the layer.
