Module space

Expand description

The logical coordinate space a tile lives in, and how a level of it splits (partition).

Modules§

Coords: An immutable coordinate/extent list whose expand’s IntoMut is the identity. Copying into mutable slots (as Sequence does) would erase constness.
CoordsExpand
LevelTable: A Partitioning with a name for each of its axes; unnamed axes print their index.
PlaneOrder: The order the planes of a launch take a level’s tiles in, where a plane level spans the launch rather than one cube (Levels::launch_planes): in blocks, each a box of tiles held by consecutive planes, the blocks taken in a CubeOrder over their grid.
Portion: The regions this instance touches and how much of the first and last is its own. Counted in the level below’s joint steps.
Shape: Every axis with its comptime extent, in canonical order.
UnitCube: The cubes a unit level spanning the launch groups its units in (Levels::launch_units): planes planes of plane_width units each. The units share nothing, so the cube is only how the launch groups them.

ComputeScope: The hardware a level’s tiles can go to, ordered inner to outer.
Count: How many tiles a level takes along one of its axes.
Coverage: How a level covers its tiles.
CubeOrder: The order a cube level distributes its boxes to the grid. A swizzle width need not divide the grid; the last strip is ragged.
Spread: How a distributed axis’s tiles are handed to a scope’s instances.
UnitShare: What the plane’s units each hold of a tile’s cells once a units level is distributed.

swizzle: Maps a linear index to 2D zigzag coordinates (x, y) within strips of num_steps steps of step_length (> 0) elements each.
