Synopsis

Documentation

newtype Ent (field :: Symbol) a Source #

Entity wrapper that adds ToJSON, FromJSON, and ElmType instances

The first type parameter field is a symbol used for the key name

>>> toElmTypeSource (Proxy :: Proxy (Ent "userId" User))
"type alias User = { userName : String, userId : Int }"
