Struct SubscriptionHandle 

pub struct SubscriptionHandle { /* private fields */ }

RAII handle returned by [Engine::subscribe_mem_changes]. Holds the consumer’s subscription id and a back-reference to the engine’s shared registry. On Drop (or via the explicit Self::unsubscribe consumer) the slot is removed from the registry — subsequent events to that mem skip the callback.

Subscriber lifetime equals the handle’s lifetime. Dropping the handle without explicit unsubscribe() is the idiomatic path — the Drop impl is sufficient.

Implementations

impl SubscriptionHandle

pub fn mem(&self) -> &str

Mem name this subscription is bound to.

pub fn unsubscribe(self)

Explicitly release the subscription. Equivalent to dropping the handle; the form exists for consumer code that wants to express intent rather than rely on scope ending.

Trait Implementations

impl Debug for SubscriptionHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for SubscriptionHandle

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
