BasicBackend

trait BasicBackend extends AnyRef

Backend for the basic database and session handling features. Concrete backends like JdbcBackend extend this type and provide concrete types for Database and Session.

Type Members

  1. trait AnyDatabaseDef extends Closeable

    Non-parameterized marker trait for any database instance, regardless of effect type.

    Non-parameterized marker trait for any database instance, regardless of effect type. Use this type when you need to refer to "any database" without knowing the effect type.

  2. trait BasicActionContext extends AnyRef

    The context object passed to SynchronousDatabaseAction instances by the execution engine.

    The context object passed to SynchronousDatabaseAction instances by the execution engine. The heavy concurrency state lives in ExecState / Ref; this is a thin wrapper that gives SDAs access to the session and statement parameters.

  3. trait BasicDatabaseDef[F[_]] extends AnyDatabaseDef

    A database instance to which connections can be created.

    A database instance to which connections can be created.

    F[_] is the effect type (e.g. cats.effect.IO). All run and stream calls on a given database instance use the same effect type.

    Concrete subclasses supply:

    • asyncF
    • controls (admission control + connection arbiter)
  4. trait BasicSessionDef extends Closeable

    A logical session of a Database.

    A logical session of a Database. The underlying database connection is created lazily on demand.

  5. abstract type Context >: Null <: BasicActionContext

    The type of the context used for running SynchronousDatabaseActions

  6. abstract type Database[F[_]] >: Null <: BasicDatabaseDef[F[_]]

    The type of database objects used by this backend, parameterized by effect type.

  7. case class ExecState(ordinal: Long, session: Option[AnyRef], sessionRelease: Option[AnyRef], transactionDepth: Int, isolationLevel: Option[Int], previousIsolationLevel: Option[Int], pinnedDepth: Int) extends Product with Serializable

    Per-db.run execution state carried through the interpreter via a CE3 Ref.

    Per-db.run execution state carried through the interpreter via a CE3 Ref.

    session is typed as Option[AnyRef] rather than Option[Session] to avoid path-dependent type issues with the abstract Session type member in Scala 2.13. Callers cast to Session as needed.

    sessionRelease holds the finalizer produced by Resource.allocated for the currently-open session + semaphore permit pair. It is set when a session is first acquired and cleared (and run) when the session is released.

  8. abstract type Session >: Null <: BasicSessionDef

    The type of session objects used by this backend.
