Struct EventListenerId 

pub struct EventListenerId<E: IxaEvent> { /* private fields */ }

An opaque token for a registered event listener.

Pass this token to Context::unsubscribe_from_event to stop the listener from receiving future emissions of the same event type.

Trait Implementations

impl<E: Clone + IxaEvent> Clone for EventListenerId<E>

fn clone(&self) -> EventListenerId<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug + IxaEvent> Debug for EventListenerId<E>

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

Formats the value using the given formatter.

impl<E: Hash + IxaEvent> Hash for EventListenerId<E>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<E: PartialEq + IxaEvent> PartialEq for EventListenerId<E>

fn eq(&self, other: &EventListenerId<E>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
