Struct PadPlan 

pub struct PadPlan { /* private fields */ }

A compiled pad traversal.

Replay fills every destination element with the caller-provided fill scalar, then copies reachable input positions into the padded output. A dense column-major destination with a unit-stride axis-0 operand and non-negative edges without interior spacing instead writes disjoint spans (low pad, operand run, high pad) per column so each element is written once.

Implementations

impl PadPlan

pub fn compile( operand_dims: &[usize], operand_strides: &[isize], dest_dims: &[usize], dest_strides: &[isize], edge_padding_low: &[i64], edge_padding_high: &[i64], interior_padding: &[i64], ) -> Result<PadPlan, StridedError>

Compile a pad plan for one operand layout and destination layout.

pub fn execute<T>( &self, dest: &mut RawStridedMut<'_, T>, operand: &RawStridedRef<'_, T>, fill: T, exec: Exec<'_>, ) -> Result<(), StridedError>

where T: Copy + Send + Sync,

Execute the prepared pad traversal.

pub fn execute_uninit<T>( &self, dest: &mut RawStridedMut<'_, MaybeUninit<T>>, operand: &RawStridedRef<'_, T>, fill: T, exec: Exec<'_>, ) -> Result<(), StridedError>

where T: Copy + Send + Sync,

Execute pad into storage whose reachable destination elements are uninitialized.
