Methods

showsPrec :: Int -> Vect n a -> ShowS #

show :: Vect n a -> String #

showList :: [Vect n a] -> ShowS #

vectMap :: (a -> b) -> Vect n a -> Vect n b Source #

A kind of fmap for Vect.

vectSnoc :: a -> Vect n a -> Vect (S n) a Source #

VCons to the end of a Vect.

vectToList :: Vect n a -> [a] Source #

Drop the length index from a Vect, giving a typical list.

listToVect :: IsNat n => [a] -> Maybe (Vect n a) Source #

Try to produce a Vect from a list. The nat index must be fixed somehow, perhaps with the help of ScopedTypeVariables.

showVect :: Show a => Vect l a -> String Source #

Show a Vect.
