Struct draw2d::graphics::vulkan::buffer::StaticBuffer

pub struct StaticBuffer { /* fields omitted */ }

A static chunk of real GPU memory. Each instance is backed by a GPU allocation.

Implementations

impl StaticBuffer

pub fn empty(
    device: Arc<Device>,
    usage: BufferUsageFlags,
    properties: MemoryPropertyFlags
) -> Result<Self>

Create a new buffer with no memory allocated.

pub fn allocate(&self, size: u64) -> Result<Self>

Allocates another buffer with the same properties as the current buffer.

pub fn create(
    device: Arc<Device>,
    usage: BufferUsageFlags,
    properties: MemoryPropertyFlags,
    size: u64
) -> Result<Self>

Create a new buffer with the specified size.

Trait Implementations

impl Buffer for StaticBuffer

unsafe fn raw(&self) -> Buffer

The raw buffer handle. Valid for the lifetime of this buffer.

unsafe fn allocation(&self) -> &Allocation

The device memory handle. Valid for the lifetime of this buffer.

fn size_in_bytes(&self) -> u64

The size, in bytes, of the allocated device memory.

impl Drop for StaticBuffer

fn drop(&mut self)

Free the buffer and any memory which is allocated.

It is the responsibility of the application to synchronize this drop with any ongoing GPU actions.
