Struct DeviceBuffer 

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

Implementations

impl<T> DeviceBuffer<T>

pub fn new() -> Self

Creates an “empty” DeviceBuffer with a null pointer and zero length.

pub fn with_capacity(len: usize) -> Self

Allocate device memory for len elements of type T.

pub fn fill_zero(&self) -> Result<(), CudaError>

Fills the buffer with zeros.

pub fn fill_zero_suffix(&self, start_idx: usize) -> Result<(), CudaError>

Fills a suffix of the buffer with zeros. The start_idx is the index in the buffer, in T elements.

pub fn len(&self) -> usize

Returns the number of elements in this buffer.

pub fn is_empty(&self) -> bool

Returns whether the buffer is empty (null pointer or zero length).

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

Returns a raw mutable pointer to the device data (typed).

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

Returns a raw const pointer to the device data (typed).

pub fn as_mut_raw_ptr(&self) -> *mut c_void

Returns a *mut c_void (untyped) pointer.

pub fn as_raw_ptr(&self) -> *const c_void

Returns a *const c_void (untyped) pointer.

pub fn as_buffer<U>(self) -> DeviceBuffer<U>

Converts the buffer to a buffer of different type. T must be composable of Us.

pub fn view(&self) -> DeviceBufferView
