toBytes :: UUID -> [Word8]

Returns the passed in UUID as a list of 16 bytes.

fromBytes :: [Word8] -> UUID

Creates a UUID out of a list of bytes. Will throw an error if the list is not of length 16.

unsafeFromBytes :: [Word8] -> UUID

Creates a UUID out of a list of bytes. Does not perform a length check on the passed in list. Behavior is undefined for lists not of length 16.

toForeignPtr :: UUID -> ForeignPtr CChar

Unsafe.

Given a UUID, returns a pointer to the 16 bytes of memory that make up the UUID.

fromForeignPtr :: ForeignPtr CChar -> UUID

Unsafe.

The passed in pointer is treated as if it were a pointer to 16 bytes of memory, which is then returned as a UUID.
