Instances details

Semigroup (JsonEndo a) Source #
Instance details Defined in HaskellWorks.Data.Aeson Methods (<>) :: JsonEndo a -> JsonEndo a -> JsonEndo a # sconcat :: NonEmpty (JsonEndo a) -> JsonEndo a # stimes :: Integral b => b -> JsonEndo a -> JsonEndo a #
Monoid (JsonEndo a) Source #
Instance details Defined in HaskellWorks.Data.Aeson Methods mempty :: JsonEndo a # mappend :: JsonEndo a -> JsonEndo a -> JsonEndo a # mconcat :: [JsonEndo a] -> JsonEndo a #
KeyValue a => KeyValue (JsonEndo a) Source #
Instance details Defined in HaskellWorks.Data.Aeson Methods (.=) :: ToJSON v => Key -> v -> JsonEndo a #

Same as object except used in combination with .?= and .!= instead of .=.

For example:

toJSON o = objectEndo
  [ "mandatory" .!= o ^. the "mandatory"
  , "optional"  .?= o ^. the "optional"
  ]

(.?=) :: (KeyValue p, ToJSON v, Monoid p) => Key -> Maybe v -> p infixr 7 Source #

Render optional fields as missing in JSON output.

(.!=) :: (KeyValue kv, ToJSON v) => Key -> v -> kv infixr 7 Source #

Same as .=, but with lower precedence to work well with lens.
