zip :: NonEmpty a -> NonEmpty b -> NonEmpty (a, b) #

The zip function takes two streams and returns a stream of corresponding pairs.

zipWith :: (a -> b -> c) -> NonEmpty a -> NonEmpty b -> NonEmpty c #

The zipWith function generalizes zip. Rather than tupling the elements, the elements are combined using the function passed as the first argument.

map :: (a -> b) -> NonEmpty a -> NonEmpty b #

Map a function over a NonEmpty stream.
