Synopsis

newtype Autodocodec a = Autodocodec {
- unAutodocodec :: a
}

Documentation

newtype Autodocodec a Source #

Autodocodec is a wrapper to provide codec-based deriving strategies.

Example usage

data Via = Via {viaOne :: !Text, viaTwo :: !Text}
  deriving stock (Show, Eq, Generic)
  deriving (FromJSON, ToJSON) via (Autodocodec Via)

instance HasCodec Via where
  codec =
    object "Via" $
      Via
        <$> requiredField "one" "first field" .= viaOne
        <*> requiredField "two" "second field" .= viaTwo
