Struct Scope 

pub struct Scope { /* private fields */ }

Hierarchical resource scope: parent close cascades to children; supports finalizers and awaitable close.

Implementations

impl Scope

pub fn make() -> Self

Creates a new root scope (open, no parent).

pub fn fork(&self) -> Self

Child scope linked under self; inherits close if the parent is already closed.

pub fn extend(&self, other: &Scope) -> bool

Reparents other under self if both are open; returns false if either is closed.

pub fn close(&self) -> bool

Closes with Exit::succeed; returns true on the first successful close.

pub fn close_with_exit(&self, exit: Exit<(), Never>) -> bool

Closes this scope and descendants, runs finalizers (LIFO) with exit, then opens the close latch.

pub fn add_finalizer(&self, finalizer: Finalizer) -> bool

Registers finalizer to run on close; returns false if already closed.

pub fn wait_closed(&self) -> Effect<(), Never, ()>

Wait until this scope has completed a successful close (including this scope’s finalizers).

pub fn close_signalled(&self) -> Effect<bool, Never, ()>

true once this scope has fired close signalling (after finalizers on the closing path).

pub fn is_closed(&self) -> bool

true if this scope or an ancestor has closed.

Trait Implementations

impl Clone for Scope

fn clone(&self) -> Scope

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Scope

fn default() -> Self

Returns the “default value” for a type.
