You can write this as:

void WaylandWindow::Configure(uint32_t time,
                              uint32_t edges,
                              ...) {
...
}

If it fits (and this is the preferred way too).

+    uint32_t edges,
+    int32_t x,
+    int32_t y,
+    int32_t width,
+    int32_t height) {
+  WaylandEvent event;
+  event.geometry_change.time = time;
+  event.geometry_change.x = x;
+  event.geometry_change.y = y;
+  event.geometry_change.width = width;
+  event.geometry_change.height = height;
+
+  widget_->OnGeometryChange(event);
+}
+
+}  // namespace ui
