How to define vkCreateXcbSurfaceKHR in Erupted-V2? - d

Question

I'm trying to use XCB with Vulkan bindings Erupted-V2 but I'm getting an error:
source/gfxdevicevulkan.d(231,24): Error: undefined identifier vkCreateXcbSurfaceKHR
Here's my dub.json:
{
"name": "dvulkanbase",
"targetType": "executable",

"dependencies": {

}
}
]
}
Here's my imports in the file that uses vkCreateXcbSurfaceKHR:
import core.stdc.string;
import erupted;
import erupted.vulkan_lib_loader;
import matrix4x4;
import std.conv;
import std.exception;
import std.stdio;
version(linux)
{
import X11.Xlib_xcb;
public import xcb.xcb;
import erupted.platform_extensions;
mixin Platform_Extensions!VK_USE_PLATFORM_XCB_KHR;
}
Here's the relevant section of the calling code:
class GfxDeviceVulkan
{
this( int width, int height, void* windowHandleOrWindow, void* display, uint window )
{
loadGlobalLevelFunctions();
VkApplicationInfo appinfo;
appinfo.pApplicationName = "VulkanBase";
appinfo.apiVersion = VK_MAKE_VERSION( 1, 0, 2 );
version(linux)
{
const(char*)[3] extensionNames = [
"VK_KHR_surface",
"VK_KHR_xcb_surface",
"VK_EXT_debug_utils",
];
}
uint extensionCount = 0;
vkEnumerateInstanceExtensionProperties( null, &extensionCount, null );
auto extensionProps = new VkExtensionProperties[]( extensionCount );
vkEnumerateInstanceExtensionProperties( null, &extensionCount, extensionProps.ptr );
uint layerCount = 0;
vkEnumerateInstanceLayerProperties( &layerCount, null );
auto layerProps = new VkLayerProperties[]( layerCount );
vkEnumerateInstanceLayerProperties( &layerCount, layerProps.ptr );
const(char*)[1] validationLayers = ["VK_LAYER_KHRONOS_validation"];
VkInstanceCreateInfo createinfo;
createinfo.sType = VkStructureType.VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;
createinfo.pApplicationInfo = &appinfo;
createinfo.enabledExtensionCount = isDebug ? cast(uint)extensionNames.length : 2;
createinfo.ppEnabledExtensionNames = extensionNames.ptr;
createinfo.enabledLayerCount = isDebug ? validationLayers.length : 0;
createinfo.ppEnabledLayerNames = isDebug ? validationLayers.ptr : null;
enforceVk( vkCreateInstance( &createinfo, null, &instance ) );
loadInstanceLevelFunctions( instance );
version(linux)
{
auto xcbInfo = VkXcbSurfaceCreateInfoKHR(
VkStructureType.VK_STRUCTURE_TYPE_XCB_SURFACE_CREATE_INFO_KHR,
null,
0,
XGetXCBConnection( cast(xcb_connection_t*)display ),
window
);
enforceVk( vkCreateXcbSurfaceKHR( instance, &xcbInfo, null, &surface ) );
}
