type Array = Vector Value

A JSON "array" (sequence).
TwoElemArray :: SumEncoding
aeson Data.Aeson Data.Aeson.TH Data.Aeson.Types
A constructor will be encoded to a 2-element array where the first element is the tag of the constructor (modified by the constructorTagModifier) and the second element the encoded contents of the constructor.
withArray :: String -> (Array -> Parser a) -> Value -> Parser a
