Struct vulkano::instance::QueueFamily

pub struct QueueFamily<'a> { /* fields omitted */ }

Represents a queue family in a physical device.

A queue family is group of one or multiple queues. All queues of one family have the same characteristics.

Methods

impl<'a> QueueFamily<'a>

fn physical_device(&self) -> PhysicalDevice<'a>

Returns the physical device associated to this queue family.

fn id(&self) -> u32

Returns the identifier of this queue family within the physical device.

fn queues_count(&self) -> usize

Returns the number of queues that belong to this family.

Guaranteed to be at least 1 (or else that family wouldn't exist).

fn supports_graphics(&self) -> bool

Returns true if queues of this family can execute graphics operations.

fn supports_compute(&self) -> bool

Returns true if queues of this family can execute compute operations.

fn supports_transfers(&self) -> bool

Returns true if queues of this family can execute transfer operations.

Note: Queues that support graphics or compute operations also always support transfer operations. As of writing this, this function will always return true. The purpose of this function is to be future-proofed in case queues that don't support transfer operations are ever added to Vulkan.

fn supports_sparse_binding(&self) -> bool

Returns true if queues of this family can execute sparse resources binding operations.

Trait Implementations

impl<'a> Debug for QueueFamily<'a>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

impl<'a> Copy for QueueFamily<'a>

impl<'a> Clone for QueueFamily<'a>

fn clone(&self) -> QueueFamily<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
