sealed abstract class Transactor[M[_]]

A thin wrapper around a source of database connections, an interpreter, and a strategy for running programs, parameterized over a target monad M and an arbitrary wrapped value A. Given a stream or program in ConnectionIO or a program in Kleisli, a Transactor can discharge the doobie machinery and yield an effectful stream or program in M.
