Struct DeviceBuffer

pub struct DeviceBuffer<T> { /* private fields */ }

Device memory buffer

Implementations

impl<T: Copy> DeviceBuffer<T>

pub fn new(len: usize, device: Arc<Device>) -> Result<Self>

Allocate a new device buffer

pub fn len(&self) -> usize

Get buffer length

pub fn is_empty(&self) -> bool

Check if buffer is empty

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

Get the device this buffer is allocated on

pub unsafe fn as_ptr(&self) -> *const T

Get raw device pointer

Safety

The caller must ensure that the returned pointer is not used after the DeviceBuffer is dropped. The caller must also ensure that the memory is not accessed concurrently.

pub unsafe fn as_mut_ptr(&mut self) -> *mut T

Get mutable raw device pointer

Safety

The caller must ensure that the returned pointer is not used after the DeviceBuffer is dropped. The caller must also ensure that the memory is not accessed concurrently.

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

Copy from host memory

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

Copy to host memory

pub fn fill(&mut self, value: T) -> Result<()>

Fill buffer with a value
