Struct vulkano::command_buffer::synced::SyncCommandBuffer

pub struct SyncCommandBuffer { /* fields omitted */ }

Command buffer built from a SyncCommandBufferBuilder that provides utilities to handle synchronization.

Implementations

impl SyncCommandBuffer

pub fn lock_submit(
    &self,
    future: &dyn GpuFuture,
    queue: &Queue
) -> Result<(), CommandBufferExecError>

Tries to lock the resources used by the command buffer.

Note: You should call this in the implementation of the CommandBuffer trait.

pub unsafe fn unlock(&self)

Unlocks the resources used by the command buffer.

Note: You should call this in the implementation of the CommandBuffer trait.

Safety

The command buffer must have been successfully locked with lock_submit().

pub fn check_buffer_access(
    &self,
    buffer: &dyn BufferAccess,
    exclusive: bool,
    queue: &Queue
) -> Result<Option<(PipelineStages, AccessFlagBits)>, AccessCheckError>

Checks whether this command buffer has access to a buffer.

Note: Suitable when implementing the CommandBuffer trait.

pub fn check_image_access(
    &self,
    image: &dyn ImageAccess,
    layout: ImageLayout,
    exclusive: bool,
    queue: &Queue
) -> Result<Option<(PipelineStages, AccessFlagBits)>, AccessCheckError>

Checks whether this command buffer has access to an image.

Note: Suitable when implementing the CommandBuffer trait.

pub fn num_buffers(&self) -> usize

pub fn buffer(
    &self,
    index: usize
) -> Option<(&dyn BufferAccess, PipelineMemoryAccess)>

pub fn num_images(&self) -> usize

pub fn image(
    &self,
    index: usize
) -> Option<(&dyn ImageAccess, PipelineMemoryAccess, ImageLayout, ImageLayout)>
