Enum Scratch 

pub enum Scratch {
    None,
    OneTile,
    WholeGrid,
}

How much of a plane’s accumulator its scratch holds at once. Serialized names are persisted in autotune keys and must not change.

Variants

None

No window: fragments store through their intrinsic, which cannot add; a drain that needs one opens OneTile.

OneTile

One tile, bounced through shared memory with three cube-wide barriers each.

WholeGrid

The plane’s whole grid, two barriers for the whole drain.

Implementations

impl Scratch

pub fn slots(self, tiles: usize) -> usize

Slots the window holds for a grid of tiles.

pub fn bounces(self) -> bool

Whether a fragment goes through shared memory on its way out; forced when partials are summed.

pub fn at_least_bouncing(self, bouncing: bool) -> Scratch

This setting raised to bouncing where bouncing demands it.
