Struct draw2d::graphics::vulkan::command_pool::ReusableCommandPool

pub struct ReusableCommandPool { /* fields omitted */ }

This struct holds a command pool and tracks which buffers have been allocated.

It allows easy reuse of transient command buffer allocations between frames.

It is the responsibility of the caller to synchronize resets and destruction.

Implementations

impl ReusableCommandPool

pub fn new(device: Arc<Device>, debug_name: impl Into<String>) -> Result<Self>

pub fn request_command_buffer(&mut self) -> Result<CommandBuffer>

Request a command buffer.

A command buffer is available if it has been allocated and has not been requested since the last call to reset.

The returned buffer is owned by this pool, the caller should not retain a reference to the buffer beyond the next call to reset.

pub unsafe fn reset(&mut self) -> Result<()>

Reset the command pool and mark return all allocated as available for use again.

Unsafe because the caller must ensure that the GPU is done with all of the allocated command buffers prior to calling this function.

Trait Implementations

impl Drop for ReusableCommandPool

fn drop(&mut self)

The owner of the TransientCommandPool must ensure that all usage of the command buffers has completed prior to dropping.
