Struct vulkano::instance::QueueFamily

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

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.

Implementations

impl<'a> QueueFamily<'a>

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

Returns the physical device associated to this queue family.

pub fn id(&self) -> u32

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

pub 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).

pub fn timestamp_valid_bits(&self) -> Option<u32>

If timestamps are supported, returns the number of bits supported by timestamp operations. The returned value will be in the range 36..64. If timestamps are not supported, returns None.

pub fn min_image_transfer_granularity(&self) -> [u32; 3]

Returns the minimum granularity supported for image transfers in terms of [width, height, depth]

pub fn supports_graphics(&self) -> bool

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

pub fn supports_compute(&self) -> bool

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

pub 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.

pub fn supports_sparse_binding(&self) -> bool

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

Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
