Enum StencilIntrinsic 

pub enum StencilIntrinsic {
    Index,
    North,
    South,
    East,
    West,
    At,
    Up,
    Down,
}

Stencil-specific intrinsics for neighbor access.

These are special intrinsics that the transpiler handles differently based on stencil configuration.

Variants

Index

Get current cell index: pos.idx()

North

Access north neighbor: pos.north(buf)

South

Access south neighbor: pos.south(buf)

East

Access east neighbor: pos.east(buf)

West

Access west neighbor: pos.west(buf)

At

Access neighbor at offset: pos.at(buf, dx, dy)

Up

3D: Access neighbor above: pos.up(buf)

Down

3D: Access neighbor below: pos.down(buf)

Implementations

impl StencilIntrinsic

pub fn from_method_name(name: &str) -> Option<Self>

Parse a method name to stencil intrinsic.

impl StencilIntrinsic

pub fn get_offset_2d(&self) -> Option<(i32, i32)>

Get the index offset for 2D stencil (relative to buffer_width).

Returns (row_offset, col_offset) where final offset is: row_offset * buffer_width + col_offset

pub fn get_offset_3d(&self) -> Option<(i32, i32, i32)>

Get the index offset for 3D stencil.

Returns (z_offset, row_offset, col_offset) where final offset is: z_offset * buffer_slice + row_offset * buffer_width + col_offset

pub fn is_3d_only(&self) -> bool

Check if this is a 3D-only intrinsic.

pub fn to_cuda_index_2d( &self, buffer_name: &str, buffer_width: &str, idx_var: &str, ) -> String

Generate CUDA index expression for 2D stencil.

Arguments

• buffer_name - Name of the buffer variable
• buffer_width - Width expression (e.g., “18” for tile_size + 2*halo)
• idx_var - Name of the current index variable

pub fn to_cuda_index_3d( &self, buffer_name: &str, buffer_width: &str, buffer_slice: &str, idx_var: &str, ) -> String

Generate CUDA index expression for 3D stencil.

Arguments

• buffer_name - Name of the buffer variable
• buffer_width - Width expression
• buffer_slice - Slice size expression (width * height)
• idx_var - Name of the current index variable

Trait Implementations

impl Clone for StencilIntrinsic

fn clone(&self) -> StencilIntrinsic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StencilIntrinsic

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

Formats the value using the given formatter.

impl PartialEq for StencilIntrinsic

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