std::optional<std::string> GetValidationLayerName ()Get the name of Vulkan validation layer if it is supported. Otherwise
return std::nullopt instead.
Defined at line 125 of file ../../src/ui/lib/escher/vk/vulkan_instance.cc
bool ValidateLayers (const std::set<std::string> & required_layer_names)Enumerate the available instance layers. Return true if all required
layers are present, and false otherwise.

bool ValidateExtensions (const std::set<std::string> & required_extension_names, const std::set<std::string> & required_layer_names)Enumerate the available instance extensions. Return true if all required
extensions are present, and false otherwise. NOTE: if an extension isn't
found at first, we look in all required layers to see if it is implemented
there.

DebugUtilsMessengerCallbackHandle RegisterDebugUtilsMessengerCallback (VkDebugUtilsMessengerCallbackFn function, void * user_data)Add debug report callback to registry. Registered callbacks are invoked
by |DebugUtilsMessengerCallbackEntrance| when validation error occurs.
The returned handle will be required when deregistering the callback.
