Struct Memcpy3DParams 

pub struct Memcpy3DParams {
    pub src_pitch: usize,
    pub dst_pitch: usize,
    pub width: usize,
    pub height: usize,
    pub depth: usize,
    pub src_height: usize,
    pub dst_height: usize,
}

Parameters for a 3D (volumetric) memory copy.

3D copies extend the 2D pitched model with a depth dimension. The source and destination are conceptually 3D arrays where each 2D “slice” has its own pitch, and slices are separated by pitch * slice_height bytes.

Fields

src_pitch: usize

Bytes per row in the source (including padding).

dst_pitch: usize

Bytes per row in the destination (including padding).

width: usize

Bytes of actual data to copy per row.

height: usize

Number of rows per slice to copy.

depth: usize

Number of slices (depth) to copy.

src_height: usize

Height of the source allocation (rows per slice, including any padding rows). Used to compute the byte stride between slices.

dst_height: usize

Height of the destination allocation (rows per slice).

Implementations

impl Memcpy3DParams

pub fn new( src_pitch: usize, dst_pitch: usize, width: usize, height: usize, depth: usize, src_height: usize, dst_height: usize, ) -> Self

Creates new 3D copy parameters.

pub fn validate(&self) -> CudaResult<()>

Validates the parameters.

Checks that width <= both pitches, height <= both allocation heights, and all dimensions are non-zero.

Errors

Returns CudaError::InvalidValue if any constraint is violated.

pub fn src_slice_stride(&self) -> usize

Returns the source byte stride between 2D slices.

pub fn dst_slice_stride(&self) -> usize

Returns the destination byte stride between 2D slices.

pub fn src_byte_extent(&self) -> usize

Returns the total source byte extent for the 3D region.

pub fn dst_byte_extent(&self) -> usize

Returns the total destination byte extent for the 3D region.

Trait Implementations

impl Clone for Memcpy3DParams

fn clone(&self) -> Memcpy3DParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Memcpy3DParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Memcpy3DParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Memcpy3DParams

fn eq(&self, other: &Memcpy3DParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
