Type Members

  1. trait All extends Read with Write with Schema with Transactional

    The bottom type of all standard effects.

    The bottom type of all standard effects. It is used by the DBIO and StreamingDBIO type aliases instead of Nothing because the compiler does not properly infer Nothing where needed. You can still introduce your own custom effect types but they will not be used by DBIO and StreamingDBIO, so you either have to define your own type aliases or spell out the proper DBIOAction types in type annotations.

  2. trait Read extends Effect

    Effect for DBIOActions that read from the database ("DQL")

  3. trait Schema extends Effect

    Effect for DBIOActions that manipulate a database schema ("DDL")

  4. trait Transactional extends Effect

    Effect for transactional DBIOActions ("DTL")

  5. trait Write extends Effect

    Effect for DBIOActions that write to the database ("DML")
