object JacksonSource
Provides helpers for creating fs2.Stream and Iterator instances of JsonEvent from various underlying event sources,
using the Jackson library as the underlying event parser.
The helpers in this object operate in terms of the IntoJacksonJsonParser typeclass, which defines logic for
using a source value to construct a Jackson JsonParser in a Resource. From there, the helpers take care of
converting the jackson parser/event model to the spac JsonEvent model.
For example:
val file = new File("./stuff.json") val jsonStream: Stream[IO, JsonEvent] = JacksonSource[IO](file)
