- 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.

SynchronousDatabaseActioninstances by the execution engine.The context object passed to
SynchronousDatabaseActioninstances 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.- Definition Classes

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). Allrunandstreamcalls on a given database instance use the same effect type.Concrete subclasses supply:
asyncFcontrols(admission control + connection arbiter)

db.runexecution state carried through the interpreter via a CE3Ref.sessionis typed asOption[AnyRef]rather thanOption[Session]to avoid path-dependent type issues with the abstractSessiontype member in Scala 2.13. Callers cast toSessionas needed.sessionReleaseholds the finalizer produced byResource.allocatedfor 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.- Definition Classes
