Struct VulkanFrameAccess 

pub struct VulkanFrameAccess(/* private fields */);

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

A record on its own is inert: editing one changes no frame. The record a VulkanFrameAccessGuard or VulkanEncodeFrameAccess writes back is reachable only through their unsafe access_mut, because the layouts and timeline values it holds must describe work actually submitted, which nothing here can check. What a guard unlocks comes from its own copy of the record begin returned, never from this one.

Implementations

impl VulkanFrameAccess

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

The frame’s images and their synchronization state.

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

The frame’s images and their synchronization state, to record the layouts and timeline values a submission leaves them in (see VulkanFrameAccessGuard::access_mut for what they must be).

pub const fn allocator(&self) -> u64

The frames context’s VkAllocationCallbacks, or zero.

pub const fn queue_family(&self) -> u32

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

pub const fn layer_count(&self) -> u32

Array layers of each image.

impl Default for VulkanFrameAccess

fn default() -> Self
