Struct vulkano::buffer::device_local::DeviceLocalBuffer

pub struct DeviceLocalBuffer<T: ?Sized, A = Arc<StdMemoryPool>> where
    A: MemoryPool,  { /* fields omitted */ }

Buffer whose content is accessible by the CPU.

Methods

impl<T> DeviceLocalBuffer<T>

fn new<'a, I>(
    device: &Arc<Device>,
    usage: &Usage,
    queue_families: I
) -> Result<Arc<DeviceLocalBuffer<T>>, OomError> where
    I: IntoIterator<Item = QueueFamily<'a>>, 

Builds a new buffer. Only allowed for sized data.

impl<T> DeviceLocalBuffer<[T]>

fn array<'a, I>(
    device: &Arc<Device>,
    len: usize,
    usage: &Usage,
    queue_families: I
) -> Result<Arc<DeviceLocalBuffer<[T]>>, OomError> where
    I: IntoIterator<Item = QueueFamily<'a>>, 

Builds a new buffer. Can be used for arrays.

impl<T: ?Sized> DeviceLocalBuffer<T>

unsafe fn raw<'a, I>(
    device: &Arc<Device>,
    size: usize,
    usage: &Usage,
    queue_families: I
) -> Result<Arc<DeviceLocalBuffer<T>>, OomError> where
    I: IntoIterator<Item = QueueFamily<'a>>, 

Builds a new buffer without checking the size.

Safety

You must ensure that the size that you pass is correct for T.

impl<T: ?Sized, A> DeviceLocalBuffer<T, A> where
    A: MemoryPool, 

fn device(&self) -> &Arc<Device>

Returns the device used to create this buffer.

fn queue_families(&self) -> Vec<QueueFamily>

Returns the queue families this buffer can be used on.
