Enum EventSubscriptionError 

pub enum EventSubscriptionError {
    Disconnected,
}

Failure reported while setting up or receiving from an event subscription.

Zero-capacity subscriber queues are rejected when subscriptions are created. Once a subscription exists, this error type reports delivery failures observed by EventSubscription.

Variants

Disconnected

The subscription can no longer receive new events.

Already queued events are delivered first. After the queue is drained, recv and try_recv return this error when the hub disconnects the subscriber, the hub is shut down, or the subscription is disconnected by its overflow policy.

Trait Implementations

impl Clone for EventSubscriptionError

fn clone(&self) -> EventSubscriptionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EventSubscriptionError

impl Debug for EventSubscriptionError

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

Formats the value using the given formatter.

impl Eq for EventSubscriptionError

impl Error for EventSubscriptionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for EventSubscriptionError

fn eq(&self, other: &EventSubscriptionError) -> 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.
