Struct draw2d::graphics::vulkan::device::QueueFamilyIndices

pub struct QueueFamilyIndices { /* fields omitted */ }

This struct holds all of the queue indices required by this application.

Implementations

impl QueueFamilyIndices

pub fn find(
    physical_device: &PhysicalDevice,
    ash: &Instance,
    window_surface: &dyn WindowSurface
) -> Result<Self>

Find all of the queue families required by this application.

Yields an Err if any of the queues cannot be found.

The implementation is greedy, e.g. the same queue will be used for multiple operations where possible.

pub fn as_queue_create_infos(&self) -> Vec<DeviceQueueCreateInfo>

Create a vector of queue create info structs based on the indices.

Automatically handles duplicate indices

pub fn get_queues(&self, logical_device: &Device) -> Result<(Queue, Queue)>

Return a tuple of the actual vulkan queues.

Handles duplicate queue family indices automatically.
