Struct SubscriptionHandle 

pub struct SubscriptionHandle { /* private fields */ }

Owns one source subscription. Dropping it cancels the subscription and stops the source’s internal polling/listening for this subscriber.

Implementations

impl SubscriptionHandle

pub fn new(cancel: impl FnOnce() + Send + Sync + 'static) -> Self

Creates a handle whose Drop runs cancel.

pub fn empty() -> Self

Creates a no-op handle (for sources that never need cleanup).

Trait Implementations

impl Debug for SubscriptionHandle

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

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.
