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

  1. abstract def addFinalizerExit(finalizer: (Exit[Any, Any]) ⇒ UIO[Any])(implicit trace: Trace): 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.

  2. abstract def forkWith(executionStrategy: ⇒ ExecutionStrategy)(implicit trace: Trace): UIO[Closeable]

    Forks a new scope that is a child of this scope.

    Forks a new scope that is a child of this scope. Finalizers added to the child scope will be run according to the specified ExecutionStrategy. The child scope will automatically be closed when this scope is closed.

  4. final def addFinalizer(finalizer: ⇒ UIO[Any])(implicit trace: Trace): UIO[Unit]

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

  9. def executionStrategy: ExecutionStrategy

    The execution strategy finalizers associated with this scope will be run with.

  10. final def extend[R]: ExtendPartiallyApplied[R]

    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.

  11. final def fork(implicit trace: Trace): UIO[Closeable]

    Forks a new scope that is a child of this scope.

    Forks a new scope that is a child of this scope. Finalizers added to this scope will be run sequentially in the reverse of the order in which they were added when this scope is closed. The child scope will automatically be closed when this scope is closed.
