A ReaderT monad transformer holding a sqlite database connection.
persistSqlite :: [EntityDef] -> Q [Dec]Source
Generate data types and instances for the given entity definitions. Can

runSqlite :: MonadCatchIO m => SqliteReader m a -> Database -> m aSource
Run a series of database actions within a single transactions. On any exception, the transaction is rolled back.
