Synopsis

The Data Type

data Str a Source

Constructors

Zero
One a
Two (Str a) (Str a)

Instances

Functor Str
Foldable Str
Traversable Str
Eq a => Eq (Str a)
Show a => Show (Str a)

strMap :: (a -> b) -> Str a -> Str bSource

strMapM :: Monad m => (a -> m b) -> Str a -> m (Str b)Source

strType :: Str a -> aSource

Take the type of the method, will crash if called

strList :: Str a -> [a]Source

Convert a Str to a list, assumes the value was created with listStr

listStr :: [a] -> Str aSource

Convert a list to a Str

strStructure :: Str a -> ([a], [a] -> Str a)Source

Transform a Str to a list, and back again, in a structure preserving way. The output and input lists must be equal in length.
