Struct Layout 

pub struct Layout {
    pub h: usize,
    pub w: usize,
    pub th: usize,
    pub tw: usize,
    pub ntx: usize,
    pub nt: usize,
    pub lanes: usize,
    pub s: usize,
    pub steps: usize,
}

Wavefront layout of one grid: tiles of th × tw, lanes lanes per tile.

Fields

h: usize

Grid height, width.

w: usize

Width.

th: usize

Tile height, width.

tw: usize

Tile width.

ntx: usize

Tile columns.

nt: usize

Tiles.

lanes: usize

Lanes per tile (≤ th); tile j uses global lanes j·lanes ...

s: usize

Slope.

steps: usize

Wavefront steps per tile.

Implementations

impl Layout

pub fn new(h: usize, w: usize, m: &Model) -> Self

Layout for an h × w grid.

pub fn tile(&self, tile: usize) -> (usize, usize, usize, usize)

Tile origin and extent (y0, x0, th, tw).

pub fn active( &self, l: usize, t: usize, tile: usize, f: impl FnMut(usize, usize), )

Pixels of lane l active at step t, as global (y, x), in decode order.

Trait Implementations

impl Clone for Layout

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Layout

impl Debug for Layout

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

Formats the value using the given formatter.
