UUID

Synopsis

Documentation

data UUID #

The UUID type. A Random instance is provided which produces version 4 UUIDs as specified in RFC 4122. The Storable and Binary instances are compatible with RFC 4122, storing the fields in network order as 16 bytes.

Random UUID 
Instance details

Defined in Data.UUID.Types.Internal

Methods

randomR :: RandomGen g => (UUID, UUID) -> g -> (UUID, g) #

random :: RandomGen g => g -> (UUID, g) #

randomRs :: RandomGen g => (UUID, UUID) -> g -> [UUID] #

randoms :: RandomGen g => g -> [UUID] #

randomRIO :: (UUID, UUID) -> IO UUID #

randomIO :: IO UUID #

toText :: UUID -> Text #

Convert a UUID into a hyphentated string using lower-case letters.

fromText :: Text -> Maybe UUID #

If the passed in Text can be parsed as an ASCII representation of a UUID, it will be. The hyphens may not be omitted.

toByteString :: UUID -> ByteString #

Encode a UUID into a ByteString in network order.

fromByteString :: ByteString -> Maybe UUID #

Extract a UUID from a ByteString in network byte order. The argument must be 16 bytes long, otherwise Nothing is returned.

toWords :: UUID -> (Word32, Word32, Word32, Word32) #

Covert a UUID into a sequence of Word32 values. Useful for when you need to serialize a UUID and neither Storable nor Binary are appropriate. Introduced in version 1.2.2.

fromWords :: Word32 -> Word32 -> Word32 -> Word32 -> UUID #

Create a UUID from a sequence of Word32. The opposite of toWords. Useful when you need a total function for constructing UUID values. Introduced in version 1.2.2.

null :: UUID -> Bool #

Returns true if the passed-in UUID is the nil UUID.

nil :: UUID #

The nil UUID, as defined in RFC 4122. It is a UUID of all zeros. null u iff u == nil.

generateNamed #

Arguments

:: UUID

Namespace

-> [Word8]

Object

-> UUID 

Generate a UUID within the specified namespace out of the given object.

Uses a SHA1 hash. The UUID is built from first 128 bits of the hash of the namespace UUID and the name (as a series of Word8).

namespaceDNS :: UUID #

The namespace for DNS addresses

namespaceURL :: UUID #

The namespace for URLs

namespaceOID :: UUID #

The namespace for ISO OIDs

namespaceX500 :: UUID #

The namespace for X.500 DNs
