    Data type representing the common setup, error-handling, and cleanup strategy associated with an SQL transaction.

    Data type representing the common setup, error-handling, and cleanup strategy associated with an SQL transaction. A Transactor uses a Strategy to wrap programs prior to execution.

    before

    a program to prepare the connection for use

    after

    a program to run on success

    oops

    a program to run on failure (catch)

    always

    a programe to run in all cases (finally)

    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.

    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.

    M

    a target effect type; typically IO
