Struct vulkano::buffer::device_local::DeviceLocalBuffer [−][src]
pub struct DeviceLocalBuffer<T: ?Sized, A = PotentialDedicatedAllocation<StdMemoryPoolAlloc>> { /* fields omitted */ }
Expand description
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.
Implementations
pub fn new<'a, I>(
device: Arc<Device>,
usage: BufferUsage,
queue_families: I
) -> Result<Arc<DeviceLocalBuffer<T>>, DeviceMemoryAllocError> where
I: IntoIterator<Item = QueueFamily<'a>>,
pub fn new<'a, I>(
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.
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>>,
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>>,
Builds a new buffer. Can be used for arrays.
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>>,
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>>,
Builds a new buffer without checking the size.
Safety
You must ensure that the size that you pass is correct for T
.
Returns the queue families this buffer can be used on.
Trait Implementations
Returns the inner information about this buffer.
Returns true if an access to self
potentially overlaps the same memory as an access to
other

Returns a key that uniquely identifies the buffer. Two buffers or images that potentially overlap in memory must return the same key. Read more
