The trait for the mesh to hold buffers

Required Methods

fn create( device: Arc<VulkanDevice>, data: &[T], cmdbuf: VkCommandBuffer, usage: VkBufferUsageFlags, ) -> Result<Self, VulkanError>

Used to create the buffer

fn get_vk_buffer(&self) -> VkBuffer

Must be able to get the VkBuffer handle

fn get_device(&self) -> Arc<VulkanDevice>

Get the device

fn set_data(&mut self, data: &[T]) -> Result<(), VulkanError>

Set data to be flushed

fn len(&self) -> usize

Get the number of the items in the buffer

fn convert_to_buffer_vec(self) -> BufferVec<T>

Convert to BufferVec<T>

fn convert_to_buffer_with_type(self) -> BufferWithType<T>

Convert to BufferWithType<T>

Provided Methods

fn flush(&mut self, _cmdbuf: VkCommandBuffer) -> Result<(), VulkanError>

Flush staging buffer data to GPU

fn discard_staging_buffer(&self)

Discard staging buffer if the buffer’s staging buffer is discardable

fn is_empty(&self) -> bool

Check if the buffer is empty

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
