Instance details

Defined in Data.Generics.Str

Methods

showsPrec :: Int -> Str a -> ShowS

show :: Str a -> String

showList :: [Str a] -> ShowS

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

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

strType :: Str a -> a #

Take the type of the method, will crash if called

strList :: Str a -> [a] #

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

listStr :: [a] -> Str a #

Convert a list to a Str

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

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