Scope

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.

final def addFinalizer(finalizer: ⇒ UIO[Any])(implicit trace: ZTraceElement): UIO[Unit]

A simplified version of addFinalizerWith when the finalizer does not depend on the Exit value that the scope is closed with.

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.
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.
