Struct FinalizerStack 

pub struct FinalizerStack { /* private fields */ }

A stack of finalizers with LIFO semantics.

Finalizers are pushed when registered (defer_async/defer_sync) and popped during region finalization. The LIFO ordering ensures resources are released in the reverse order they were acquired.

Implementations

impl FinalizerStack

pub fn new() -> Self

Creates a new empty finalizer stack.

pub fn with_escalation(escalation: FinalizerEscalation) -> Self

Creates a new finalizer stack with the specified escalation policy.

pub const fn escalation(&self) -> FinalizerEscalation

Returns the escalation policy.

pub fn push(&mut self, finalizer: Finalizer)

Pushes a finalizer onto the stack.

pub fn pop(&mut self) -> Option<Finalizer>

Pops a finalizer from the stack (LIFO order).

pub fn len(&self) -> usize

Returns the number of pending finalizers.

pub fn is_empty(&self) -> bool

Returns true if there are no pending finalizers.

pub fn push_sync<F>(&mut self, f: F)

where F: FnOnce() + Send + 'static,

Pushes a synchronous finalizer.

pub fn push_async<F>(&mut self, future: F)

where F: Future<Output = ()> + Send + 'static,

Pushes an asynchronous finalizer.
