Instances

Show Parsed Source #
Instance details Defined in Text.StringRandom.Parser Methods showsPrec :: Int -> Parsed -> ShowS # show :: Parsed -> String # showList :: [Parsed] -> ShowS #
Eq Parsed Source #
Instance details Defined in Text.StringRandom.Parser Methods (==) :: Parsed -> Parsed -> Bool # (/=) :: Parsed -> Parsed -> Bool #

processParse :: Text -> Either String Parsed Source #

processParse parses the regular expression string and returns an abstract syntax tree. If there is an error in the regular expression, it returns the Left value.
