Expand description

Cached nullable PFNs for Global dispatch.

A resolved pointer does not establish enabled API, extension or feature state. Keep the native objects and supplying library alive while using these pointers.

Fields§

§create_instance: PFN_vkCreateInstance

Cached function pointer for vkCreateInstance.

Khronos reference: vkCreateInstance

§get_instance_proc_addr: PFN_vkGetInstanceProcAddr

Cached function pointer for vkGetInstanceProcAddr.

Khronos reference: vkGetInstanceProcAddr

§enumerate_instance_version: PFN_vkEnumerateInstanceVersion

Cached function pointer for vkEnumerateInstanceVersion.

Khronos reference: vkEnumerateInstanceVersion

§enumerate_instance_layer_properties: PFN_vkEnumerateInstanceLayerProperties

Cached function pointer for vkEnumerateInstanceLayerProperties.

Khronos reference: vkEnumerateInstanceLayerProperties

§enumerate_instance_extension_properties: PFN_vkEnumerateInstanceExtensionProperties

Cached function pointer for vkEnumerateInstanceExtensionProperties.

Khronos reference: vkEnumerateInstanceExtensionProperties

Implementations§

impl FnEntry

pub unsafe fn new_from_resolver( load: unsafe extern "system" fn(InstanceHandle, *const c_char) -> PFN_vkVoidFunction, ) -> Self

Load all commands for this dispatch level.

§Safety

load must implement the Vulkan proc-addr contract and remain callable for the lifetime of this table and all derived raw function pointers.
