Struct screen_13::driver::QueueFamilyProperties

pub struct QueueFamilyProperties {
    pub queue_flags: QueueFlags,
    pub queue_count: u32,
    pub timestamp_valid_bits: u32,
    pub min_image_transfer_granularity: [u32; 3],
}

Describes additional propeties of the current execution queue.

Fields

queue_flags: QueueFlags

Bitmask specifying capabilities of queues in a queue family.

queue_count: u32

Number of queues which are available.

timestamp_valid_bits: u32

The unsigned integer count of meaningful bits in the timestamps written via vkCmdWriteTimestamp2 or vkCmdWriteTimestamp.

The valid range for the count is 36 to 64 bits, or a value of 0, indicating no support for timestamps. Bits outside the valid range are guaranteed to be zeros.

min_image_transfer_granularity: [u32; 3]

The minimum granularity supported for image transfer operations on the queues in this queue family.

Trait Implementations

impl Clone for QueueFamilyProperties

fn clone(&self) -> QueueFamilyProperties

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueueFamilyProperties

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

Formats the value using the given formatter.

impl Hash for QueueFamilyProperties

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl PartialEq<QueueFamilyProperties> for QueueFamilyProperties

fn eq(&self, other: &QueueFamilyProperties) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
