Struct VulkanFrameAccess 

Source 
pub struct VulkanFrameAccess(/* private fields */);
Expand description

Locked FFmpeg Vulkan surface state passed to the native GPU boundary.

Editing a record changes no frame by itself. The record a guard writes back is reachable only through the unsafe access_mut, since its values must describe work actually submitted.

Implementations§

Source§

impl VulkanFrameAccess

Source

pub const fn frame(&self) -> &VulkanFrameDescriptor

The frame’s images and their synchronization state.

Source

pub const fn frame_mut(&mut self) -> &mut VulkanFrameDescriptor

Mutable frame state; see VulkanFrameAccessGuard::access_mut for what it must hold.

Source

pub const fn allocator(&self) -> u64

The frames context’s VkAllocationCallbacks, or zero.

Source

pub const fn queue_family(&self) -> u32

The queue family the frame’s images are owned by.

Source

pub const fn layer_count(&self) -> u32

Array layers of each image.
