DisposableTracker

Struct DisposableTracker 

Source
pub struct DisposableTracker { /* private fields */ }
Expand description

A tracker that can be manually disposed before it’s dropped.

Unlike Tracker, DisposableTracker provides a dispose() method to explicitly clean up all subscriptions. This is useful for long-lived objects that need to clear subscriptions mid-lifecycle.

DisposableTracker is Clone - all clones share the same internal state via Rc. Subscriptions are cleaned up when ALL DisposableTracker clones are dropped. Tracker clones do NOT count towards this - only DisposableTracker ownership matters.

Implementations§

Source§

impl DisposableTracker

Source

pub fn new() -> Self

Creates a new empty DisposableTracker.

Source

pub fn tracker(&self) -> &Tracker

Returns the underlying Tracker for use with subscribe methods.

Source

pub fn dispose(&mut self)

Manually disposes all tracked subscriptions.

After calling this, the tracker is still valid and can track new subscriptions, but all previous subscriptions are cleaned up.

Source

pub fn subscription_count(&self) -> usize

Returns the number of active subscriptions tracked.
