Enum QueueFamily 

pub enum QueueFamily {
    Explicit(u32),
    External,
    Foreign,
}

One side of a QueueFamilyOwnershipTransfer.

The named variants stand for the queue families that Vulkan reserves for resources shared outside the current device; Explicit carries an ordinary queue family index, such as the one returned by vulkan::Device::queue_family_index.

Variants

Explicit(u32)

A specific queue family, identified by its index.

External

The queue family of an external, non-Vulkan API (VK_QUEUE_FAMILY_EXTERNAL).

Foreign

The queue family of a foreign consumer of the memory, such as a different device or the kernel (VK_QUEUE_FAMILY_FOREIGN_EXT).

Requires the VK_EXT_queue_family_foreign extension.

Trait Implementations

impl Clone for QueueFamily

fn clone(&self) -> QueueFamily

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueueFamily

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

Formats the value using the given formatter.

impl PartialEq for QueueFamily

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

Tests for self and other values to be equal, and is used by ==.

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

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