Synopsis

Documentation

data h :. t infixr 3 #

A composite type to parse your custom data structures without having to define dummy newtype wrappers every time.

instance FromRow MyData where ...
instance FromRow MyData2 where ...

then I can do the following for free:

res <- query' c "..."
forM res $ \(MyData{..} :. MyData2{..}) -> do
  ....
