Description

Structurally tag binary serialisation stream. Useful when most Binary instances are Generic derived.

Say you have a data type

data Record = Record
  { _recordFields  :: HM.HashMap Text (Integer, ByteString)
  , _recordEnabled :: Bool
  }
  deriving (Eq, Show, Generic)

instance Binary Record
instance Structured Record

then you can serialise and deserialise Record values with a structure tag by simply

structuredEncode record :: ByteString
structuredDecode lbs :: IO Record

If structure of Record changes in between, deserialisation will fail early.

Technically, Structured is not related to Binary, and may be useful in other uses.

Encoding and decoding

These functions operate like binary's counterparts, but the serialised version has a structure hash in front.

structuredEncode :: (Binary a, Structured a) => a -> ByteString Source #

Structured encode. Encode a value to using binary serialisation to a lazy ByteString. Encoding starts with 16 byte large structure hash.

structuredEncodeFile :: (Binary a, Structured a) => FilePath -> a -> IO () Source #

Lazily serialise a value to a file

structuredDecode :: (Binary a, Structured a) => ByteString -> a Source #

Structured decode. Decode a value from a lazy ByteString, reconstructing the original structure. Throws pure exception on invalid inputs.

structuredDecodeOrFailIO :: (Binary a, Structured a) => ByteString -> IO (Either String a) Source #

structuredDecodeFileOrFail :: (Binary a, Structured a) => FilePath -> IO (Either String a) Source #

Lazily reconstruct a value previously written to a file.

Structured class

class Typeable a => Structured a where Source #

Class of types with a known Structure.

For regular data types Structured can be derived generically.

data Record = Record { a :: Int, b :: Bool, c :: [Char] } deriving (Generic)
instance Structured Record

Since: Cabal-syntax-3.2.0.0
