sizeSequence :: (IsSequence mono, Flat (Element mono)) => mono -> NumBits -> NumBits Source #
Calculate size of an instance of IsSequence as the sum: * of the size of all the elements * plus the size of the array constructors (1 byte every 255 elements plus one final byte)
encodeSequence :: (Flat (Element mono), MonoFoldable mono) => mono -> Encoding Source #
Encode an instance of IsSequence, as an array
decodeSequence :: (Flat (Element b), IsSequence b) => Get b Source #
Decode an instance of IsSequence, as an array
encodeList :: (Flat (Element mono), MonoFoldable mono) => mono -> Encoding Source #
decodeList :: (IsSequence b, Flat (Element b)) => Get b Source #
encodeMap :: (Flat (ContainerKey map), Flat (MapValue map), IsMap map) => map -> Encoding Source #
Encode an instance of IsMap, as a list of (Key,Value) tuples
decodeMap :: (Flat (ContainerKey map), Flat (MapValue map), IsMap map) => Get map Source #
Decode an instance of IsMap, as a list of (Key,Value) tuples
Sequences are defined as Arrays:
Array v = A0 | A1 v (Array v) | A2 v v (Array v) ... | A255 ... (Array v)
In practice, this means that the sequence is encoded as a sequence of blocks of up to 255 elements, with every block preceded by the count of the elements in the block and a final 0-length block.
Lists are defined as:
List a ≡ Nil | Cons a (List a)
The AsList/AsArray wrappers can be used to serialise sequences as Lists or Arrays
>>>
tst $ AsArray ([]::[()])
(True,8,[0])
>>>
tst $ AsArray [11::Word8,22,33]
(True,40,[3,11,22,33,0])
>>>
tst $ AsList ([]::[()])
(True,1,[0])
>>>
tst (AsList [11::Word8,22,33])
(True,28,[133,197,164,32])
>>>
tst (AsSet (Data.Set.fromList [11::Word8,22,33]))
(True,28,[133,197,164,32])
Maps are saved as lists of (key,value) tuples.
>>>
tst (AsMap (Data.Map.fromList ([]::[(Word8,())])))
(True,1,[0])
>>>
tst (AsMap (Data.Map.fromList [(3::Word,9::Word)]))
(True,18,[129,132,128])
