Implementations§

impl PerformanceQuery

pub fn new(entry: &Entry, instance: &Instance) -> Self

pub unsafe fn enumerate_physical_device_queue_family_performance_query_counters_len( &self, physical_device: PhysicalDevice, queue_family_index: u32, ) -> VkResult<usize>

Retrieve the number of elements to pass to enumerate_physical_device_queue_family_performance_query_counters()

pub unsafe fn enumerate_physical_device_queue_family_performance_query_counters( &self, physical_device: PhysicalDevice, queue_family_index: u32, out_counters: &mut [PerformanceCounterKHR], out_counter_descriptions: &mut [PerformanceCounterDescriptionKHR], ) -> VkResult<()>

https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/vkEnumeratePhysicalDeviceQueueFamilyPerformanceQueryCountersKHR.html

Call enumerate_physical_device_queue_family_performance_query_counters_len() to query the number of elements to pass to out_counters and out_counter_descriptions. Be sure to Default::default()-initialize these elements and optionally set their p_next pointer.
