functions based on generate

generate :: (acc -> Maybe (y, acc)) -> acc -> T y Source

unfoldR :: (acc -> Maybe (y, acc)) -> acc -> T y Source

generateInfinite :: (acc -> (y, acc)) -> acc -> T y Source

fromList :: [y] -> T y Source

toList :: T y -> [y] Source

toStorableSignal :: Storable y => ChunkSize -> T y -> Vector y Source

fromStorableSignal :: Storable y => Vector y -> T y Source

iterate :: (a -> a) -> a -> T a Source

iterateAssociative :: (a -> a -> a) -> a -> T a Source

repeat :: a -> T a Source

functions based on crochetL

crochetL :: (x -> acc -> Maybe (y, acc)) -> acc -> T x -> T y Source

scanL :: (acc -> x -> acc) -> acc -> T x -> T acc Source

scanLClip :: (acc -> x -> acc) -> acc -> T x -> T acc Source

input and output have equal length, that's better for fusion

map :: (a -> b) -> T a -> T b Source

unzip :: T (a, b) -> (T a, T b) Source

unzip3 :: T (a, b, c) -> (T a, T b, T c) Source

delay1 :: a -> T a -> T a Source

This is a fusion friendly implementation of delay. However, in order to be a crochetL the output has the same length as the input, that is, the last element is removed - at least for finite input.

delay :: y -> Int -> T y -> T y Source

take :: Int -> T a -> T a Source

takeWhile :: (a -> Bool) -> T a -> T a Source

replicate :: Int -> a -> T a Source

functions consuming multiple lists

foldL' :: (x -> acc -> acc) -> acc -> T x -> acc Source

foldL :: (acc -> x -> acc) -> acc -> T x -> acc Source

lengthSlow :: T a -> Int Source

can be used to check against native length implementation
