accessors :: Lookup a => AccessorTree a Source #
describeGAField :: GAField a -> String Source #
sameFieldType :: GAField a -> GAField b -> Bool Source #
Returns True if the type of fields is the same.
showFlat :: forall a. AccessorTree a -> Bool -> (Double -> String) -> a -> String Source #
Show a list of values . True --> align the colums, False --> total mayhem
