Struct ccthw::graphics::vulkan_api::OneTimeSubmitCommandBuffer

pub struct OneTimeSubmitCommandBuffer { /* private fields */ }

A utility for managing a small command pool which runs synchronous commands.

Implementations

impl OneTimeSubmitCommandBuffer

pub unsafe fn new( render_device: Arc<RenderDevice>, queue: Queue ) -> Result<Self, GraphicsError>

Create a new one time submit command buffer.

Params

• render_device: used to create the underlying Vulkan resources
• queue: The queue which will be used for command buffer submission

Safety

Unsafe because:

• The application must destroy this resource before exiting.

pub unsafe fn command_buffer(&self) -> CommandBuffer

Get the current command buffer.

Safety

Unsafe because:

• the caller must not hold the command buffer after submission
• the command buffer is always ready for commands, there is no need to call vkBeginCommandBuffer
• the command buffer never needs to be explicitly ended by vkEndCommandBuffer

pub unsafe fn sync_submit_and_reset(&mut self) -> Result<(), GraphicsError>

Submit the current command buffer and block the CPU until all commands complete on the GPU.

Safety

Unsafe because:

• the application is responsible for synchronizing access to any resources referenced by the commands as they execute.
