Mafic

data Mafic a b t Source #

This is used to generate an indexed magma from an unindexed source

By constructing it this way we avoid infinite reassociations in sums where possible.

Constructors

Mafic Int (Int -> Magma Int t b a)

runMafic :: Mafic a b t -> Magma Int t b a Source #

Generate a Magma using from a prefix sum.

TakingWhile

data TakingWhile (p :: Type -> Type -> Type) (g :: Type -> Type) a b t Source #

This is used to generate an indexed magma from an unindexed source

By constructing it this way we avoid infinite reassociations where possible.

In TakingWhile p g a b t, g has a nominal role to avoid exposing an illegal _|_ via Contravariant, while the remaining arguments are degraded to a nominal role by the invariants of Magma

Constructors

TakingWhile Bool t (Bool -> Magma () t b (Corep p a))
