Struct GpuPad 

pub struct GpuPad {
    pub pads: Vec<(usize, usize)>,
    pub value: Arc<Tensor>,
}

Constant padding via two copy_nds: broadcast the pad value across the whole output, then drop the input into the interior. No dedicated kernel. Reflect/ Edge modes are left on the host (see GpuPad::from_core).

Fields

pads: Vec<(usize, usize)>

value: Arc<Tensor>

Implementations

impl GpuPad

pub fn from_core(op: &Pad) -> Option<Self>

impl Op for GpuPad

fn name(&self) -> StaticName

fn as_typed(&self) -> Option<&dyn TypedOp>

fn validation(&self) -> Validation

The kind of accuracy check that should be performed on operation when testing them.

fn info(&self) -> Result<Vec<String>, Error>

Short (one-line) strings giving hints on internal implementation or important configuration details to be displayed in dumps.

impl PartialEq for GpuPad

fn eq(&self, other: &GpuPad) -> 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.
