Data.Array.Parallel.PArray.PRepr

Defines the PRepr family and PA class that converts between the user level element types and our generic representation. Apart from unpackPA, the PA wrapper functions defined here all have equivalent PR versions in Data.Array.Parallel.PArray.PData, so see there for documentation.

Documentation

type family PRepr a

Family of Representable types. These are the types that we know how to represent generically. PRepr takes an arbitrary type and produces the generic type we use to represent it.

Instances for simple types are defined by the library. For algebraic types, it's up to the vectoriser/client module to create a suitable instance.

class PR (PRepr a) => PA a where

A PA dictionary contains the functions that we use to convert a representable type to and from its generic representation.

The conversions methods should all be O(1).
