Attribute Macro auto_globalhooksinfo_impl

#[auto_globalhooksinfo_impl]

Derive the implementation of the vulkan_layer::GlobalHooksInfo trait from the implementation of the vulkan_layer::GlobalHooks trait.

This attribute macro should be used over an implementation item of the vulkan_layer::GlobalHooks trait, and will implement the vulkan_layer::GlobalHooksInfo trait for the type:

• GlobalHooksInfo::hooked_commands returns a list of the overridden methods that appear in the implementation item.
• GlobalHooksInfo::HooksType and GlobalHooksInfo::HooksRefType are defined as Self and &Self.
• GlobalHooksInfo::hooks returns self.

Examples

use ash::vk;
use vulkan_layer::{
    auto_globalhooksinfo_impl, GlobalHooks, GlobalHooksInfo, LayerResult, LayerVulkanCommand,
    VkLayerInstanceLink,
};

#[derive(Default)]
struct MyGlobalHooks;

#[auto_globalhooksinfo_impl]
impl GlobalHooks for MyGlobalHooks {
    fn create_instance(
        &self,
        _p_create_info: &vk::InstanceCreateInfo,
        _layer_instance_link: &VkLayerInstanceLink,
        _p_allocator: Option<&vk::AllocationCallbacks>,
        _p_instance: *mut vk::Instance,
    ) -> LayerResult<ash::prelude::VkResult<()>> {
        LayerResult::Unhandled
    }
}

let my_global_hooks: MyGlobalHooks = Default::default();
assert!(std::ptr::eq(&my_global_hooks, my_global_hooks.hooks()));
assert_eq!(
    MyGlobalHooks::hooked_commands(),
    [LayerVulkanCommand::CreateInstance]
);
