Fields

width: usize

height: usize

num_channels: usize

pitch: usize

Implementations

impl<T: Copy> DeviceBuffer2D<T>

pub fn new(width: usize, height: usize, num_channels: usize) -> Self

pub unsafe fn copy_from_async( &mut self, other: &HostBuffer<T>, stream: &Stream, ) -> Result<(), Error>

Copy from host buffer.

Safety

This function is marked unsafe because it does not synchronize and the operation might not have completed when it returns.

pub unsafe fn copy_to_async( &self, other: &mut HostBuffer<T>, stream: &Stream, ) -> Result<(), Error>

Copy to host buffer.

Safety

This function is marked unsafe because it does not synchronize and the operation might not have completed when it returns.

pub fn fill_with_byte( &mut self, value: u8, stream: &Stream, ) -> Result<(), Error>

Fill buffer with byte value.

pub fn num_elements(&self) -> usize

pub fn as_internal(&self) -> &DevicePtr

Get readonly reference to internal DevicePtr.

pub fn as_mut_internal(&mut self) -> &mut DevicePtr

Get mutable reference to internal DevicePtr.

pub unsafe fn free(&mut self)

Release the buffer memory.

Panics

This function panics if binding to the corresponding device fails.

Safety

The buffer may not be used after this function is called, except for being dropped.

Trait Implementations

impl<T: Copy> Drop for DeviceBuffer2D<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: Copy> Send for DeviceBuffer2D<T>

Implements Send for DeviceBuffer2D.

Safety

This property is inherited from the CUDA API, which is thread-safe.

impl<T: Copy> Sync for DeviceBuffer2D<T>

Implements Sync for DeviceBuffer2D.

Safety

This property is inherited from the CUDA API, which is thread-safe.
