Struct vulkano::buffer::device_local::DeviceLocalBuffer
[−]
[src]
pub struct DeviceLocalBuffer<T: ?Sized, A = PotentialDedicatedAllocation<StdMemoryPoolAlloc>> { /* fields omitted */ }
Buffer whose content is in device-local memory.
This buffer type is useful in order to store intermediary data. For example you execute a compute shader that writes to this buffer, then read the content of the buffer in a following compute or graphics pipeline.
The DeviceLocalBuffer
will be in device-local memory, unless the device doesn't provide any
device-local memory.
Methods
impl<T> DeviceLocalBuffer<T>
[src]
pub fn new<'a, I>(
device: Arc<Device>,
usage: BufferUsage,
queue_families: I
) -> Result<Arc<DeviceLocalBuffer<T>>, DeviceMemoryAllocError> where
I: IntoIterator<Item = QueueFamily<'a>>,
[src]
device: Arc<Device>,
usage: BufferUsage,
queue_families: I
) -> Result<Arc<DeviceLocalBuffer<T>>, DeviceMemoryAllocError> where
I: IntoIterator<Item = QueueFamily<'a>>,
Builds a new buffer. Only allowed for sized data.
impl<T> DeviceLocalBuffer<[T]>
[src]
pub fn array<'a, I>(
device: Arc<Device>,
len: usize,
usage: BufferUsage,
queue_families: I
) -> Result<Arc<DeviceLocalBuffer<[T]>>, DeviceMemoryAllocError> where
I: IntoIterator<Item = QueueFamily<'a>>,
[src]
device: Arc<Device>,
len: usize,
usage: BufferUsage,
queue_families: I
) -> Result<Arc<DeviceLocalBuffer<[T]>>, DeviceMemoryAllocError> where
I: IntoIterator<Item = QueueFamily<'a>>,
Builds a new buffer. Can be used for arrays.
impl<T: ?Sized> DeviceLocalBuffer<T>
[src]
pub unsafe fn raw<'a, I>(
device: Arc<Device>,
size: usize,
usage: BufferUsage,
queue_families: I
) -> Result<Arc<DeviceLocalBuffer<T>>, DeviceMemoryAllocError> where
I: IntoIterator<Item = QueueFamily<'a>>,
[src]
device: Arc<Device>,
size: usize,
usage: BufferUsage,
queue_families: I
) -> Result<Arc<DeviceLocalBuffer<T>>, DeviceMemoryAllocError> 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>
[src]
pub fn queue_families(&self) -> Vec<QueueFamily>
[src]
Returns the queue families this buffer can be used on.

Returns the size of the buffer in bytes.
fn conflicts_buffer(&self, other: &BufferAccess) -> bool
[src]
Returns true if an access to self
potentially overlaps the same memory as an access to other
. Read more
