-- Hoogle documentation, generated by Haddock -- See Hoogle, http://www.haskell.org/hoogle/ -- | Library for IP and MAC addresses -- -- The ip package provides types and functions for dealing with -- IPv4 addresses, CIDR blocks, and MAC addresses. We provide instances -- for typeclasses found in commonly used packages like aeson, -- vector, and hashable. We also provide Parsers for -- working with attoparsec. -- -- Notably, this package does not overload functions by introducing any -- typeclasses of its own. Neither does it prefix functions with the name -- of the type that they work on. Instead, functions of the same name are -- exported by several different modules, and it is expected that end -- users disambiguate by imported these modules qualified. For example, -- Data.IPv4.Text and Data.IPv4.ByteString.Char8 have -- nearly identical export lists. -- -- The only module intended to be imported unqualified is -- Net.Types. The types in this package should not conflict with -- the types in any other commonly used packages. -- -- The following packages are intended to be used with this package: -- -- @package ip @version 0.8.5 module Net.Internal eitherToAesonParser :: Either String a -> Parser a attoparsecParseJSON :: Parser a -> Value -> Parser a stripDecimal :: Text -> Either String Text decodeIPv4TextReader :: Reader Word32 decodeIPv4TextEither :: Text -> Either String Word32 ipOctetSizeErrorMsg :: String rightToMaybe :: Either a b -> Maybe b toDotDecimalText :: Word32 -> Text toDotDecimalBuilder :: Word32 -> Builder rangeToDotDecimalText :: Word32 -> Word8 -> Text rangeToDotDecimalBuilder :: Word32 -> Word8 -> Builder -- | I think that this function can be improved.

--   public x == not (reserved x)
--
public :: IPv4 -> Bool module Net.IPv4.Range -- | Normalize an IPv4Range. The first result of this is that the -- IPv4 inside the IPv4Range is changed so that the -- insignificant bits are zeroed out. For example: -- -- 
--   >>> prRange $ normalize $ IPv4Range (fromOctets 192 168 1 19) 24
--   192.168.1.0/24
--

--
-- -- The second effect of this is that the mask length is lowered to be 32 -- or smaller. Working with IPv4Ranges that have not been -- normalized does not cause any issues for this library, although other -- applications may reject such ranges (especially those with a mask -- length above 32). -- -- Note that normalize is idempotent, that is: -- -- 
--   normalize r == (normalize . normalize) r
--

--   False
--
-- -- Typically, element-testing functions are written to take the element -- as the first argument and the set as the second argument. This is -- intentionally written the other way for better performance when -- iterating over a collection. For example, you might test elements in a -- list for membership like this: -- -- 
--   >>> let r = IPv4Range (fromOctets 10 10 10 6) 31
--   
--   >>> mapM_ (print . contains r) (take 5 $ iterate succ $ fromOctets 10 10 10 5)
--   False
--   True
--   True
--   False
--   False
--

--   10.10.1.128
