Napkin.Run.Effects.Interpreters.FakeLocal

Description

A SqlBackend interpreter that performs a minimal amount of table state management to facilitate dry runs and trivial unwrapping of SqlBackend effects.

It produces a report of used depedencies, but this is not intended for use in the Spec system for figuring out dependencies. User's forced/added dependencies would not show up here, for example. This is meant more for dry runs and simulations.

Synopsis

- _istate_hidden :: Set (Ref Table)
- _istate_targetCheck :: Bool
}
istate_targetCheck :: Lens' IState Bool
istate_managed :: Lens' IState (Set (Ref Table))
istate_hidden :: Lens' IState (Set (Ref Table))
istate_external :: Lens' IState (Set (Ref Table))
istate_created :: Lens' IState (Set (Ref Table))
emptyIState :: IState
createReference :: Member (State IState) r => Ref Table -> Sem r ()
