Ribosome.Host.Class.Msgpack.Map

Helper for encoding values to a heterogeneous MessagePack map.

Documentation

class MsgpackMapElem a where

Utility class for MsgpackMap.

Methods

msgpackMapElem :: a -> Map Text Object

Instances

(MsgpackEncode a, t ~ Text) => MsgpackMapElem (t, Maybe a)

Defined in Ribosome.Host.Class.Msgpack.Map

Methods

msgpackMapElem :: (t, Maybe a) -> Map Text Object

(MsgpackEncode a, t ~ Text) => MsgpackMapElem (t, a)

Defined in Ribosome.Host.Class.Msgpack.Map

Methods

msgpackMapElem :: (t, a) -> Map Text Object

class MsgpackMap a where

This class provides a variadic method for encoding MessagePack maps.

Methods

msgpackMap :: a

Encode an arbitrary number of heterogeneously typed values to a single MessagePack map. This function is variadic, meaning that it takes an arbitrary number of arguments:

>>> msgpackMap ("number", 5 :: Int) ("status", "error" :: Text) ("intensity", 3.14 :: Double) :: Object
ObjectMap (Map.fromList [(ObjectString "number", ObjectInt 5), (ObjectString "status", ObjectString "error"), (ObjectString "intensity", ObjectFloat 3.14)])

This avoids the need to call toMsgpack once for each element and then once more for the map.
