Documentation

data S r1

Hints that evaluating this array is only a small amount of work. It will be evaluated sequentially in the main thread, instead of in parallel on the gang. This avoids the associated scheduling overhead.

(Shape sh, FillRange r1 r2 sh e) => FillRange (S r1) r2 sh e

(Shape sh, Fill r1 r2 sh e) => Fill (S r1) r2 sh e

Combine r1 a r2 b => Combine (S r1) a (S r2) b

Read (Array r1 sh e) => Read (Array (S r1) sh e)

Show (Array r1 sh e) => Show (Array (S r1) sh e)

data family Array r sh e

Arrays with a representation tag, shape, and element type. Use one of the type tags like D, U and so on for r, one of DIM1, DIM2 ... for sh.
