class MsgpackMap a where Source #

This class provides a variadic method for encoding MessagePack maps.

Methods

msgpackMap :: a Source #

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.
