Showing

explicitShow :: Show a => RAList a -> String Source #

explicitShowsPrec :: Show a => Int -> RAList a -> ShowS Source #

Construction

empty :: RAList a Source #

Empty RAList.

>>> empty :: RAList Int
fromList []

singleton :: a -> RAList a Source #

Single element RAList.

cons :: a -> RAList a -> RAList a Source #

cons for non-empty rals.

Indexing

(!) :: RAList a -> Int -> a Source #

(!?) :: RAList a -> Int -> Maybe a Source #

safe list index.

>>> fromList ['a'..'f'] !? 0
Just 'a'

>>> fromList ['a'..'f'] !? 5
Just 'f'

>>> fromList ['a'..'f'] !? 6
Nothing

uncons :: RAList a -> Maybe (a, RAList a) Source #

>>> uncons $ fromList []
Nothing

>>> uncons $ fromList "abcdef"
Just ('a',fromList "bcdef")

length :: RAList a -> Int Source #

null :: RAList a -> Bool Source #

Conversions

toList :: RAList a -> [a] Source #

fromList :: [a] -> RAList a Source #

>>> fromList ['a' .. 'f']
fromList "abcdef"

>>> explicitShow $ fromList ['a' .. 'f']
"NonEmpty (NE (Cons0 (Cons1 (Nd (Lf 'a') (Lf 'b')) (Last (Nd (Nd (Lf 'c') (Lf 'd')) (Nd (Lf 'e') (Lf 'f')))))))"

Folding

ifoldMap :: Monoid m => (Int -> a -> m) -> RAList a -> m Source #

Mapping

adjust :: forall a. Int -> (a -> a) -> RAList a -> RAList a Source #

Adjust a value in the list.

>>> adjust 3 toUpper $ fromList "bcdef"
fromList "bcdEf"

If index is out of bounds, the list is returned unmodified.

>>> adjust 10 toUpper $ fromList "bcdef"
fromList "bcdef"

>>> adjust (-1) toUpper $ fromList "bcdef"
fromList "bcdef"

map :: (a -> b) -> RAList a -> RAList b Source #

>>> map toUpper (fromList ['a'..'f'])
fromList "ABCDEF"

imap :: (Int -> a -> b) -> RAList a -> RAList b Source #

>>> imap (,) $ fromList ['a' .. 'f']
fromList [(0,'a'),(1,'b'),(2,'c'),(3,'d'),(4,'e'),(5,'f')]

itraverse :: forall f a b. Applicative f => (Int -> a -> f b) -> RAList a -> f (RAList b) Source #
