IOActions

doobie.util.io$.IOActions
class IOActions[M[_]](implicit M: Sync[M])

Constructor for a module of IO operations in some effectful monad. This is by no means complete; contributions welcome. The construtors here expose naked lifetime-managed objects and should be used with caution; they are mostly intended for library authors who wish to integrate vendor- specific behavior that relies on JDK IO.
