trait Scope extends Serializable
A Scope
is the foundation of safe, composable resource management in ZIO. A
scope has two fundamental operators, addFinalizer
, which adds a finalizer
to the scope, and close
, which closes a scope and runs all finalizers that
have been added to the scope.

Abstract Value Members
- abstract def addFinalizerExit(finalizer: (Exit[Any, Any]) => UIO[Any])(implicit trace: ZTraceElement): UIO[Unit]
Adds a finalizer to this scope.
Adds a finalizer to this scope. The finalizer is guaranteed to be run when the scope is closed.
- abstract def fork(implicit trace: ZTraceElement): UIO[Closeable]
Forks a new scope that is a child of this scope.
Forks a new scope that is a child of this scope. The child scope will automatically be closed when this scope is closed.

Extends the scope of a

workflow that needs a scope into this scope by providing it to the workflow but not closing the scope when the workflow completes execution.Extends the scope of a
ZIO
workflow that needs a scope into this scope by providing it to the workflow but not closing the scope when the workflow completes execution. This allows extending a scoped value into a larger scope. - def finalize(): Unit
