Enum RecvError 

#[non_exhaustive]
pub enum RecvError {
    Closed,
    Lagged(Lagged),
}

Error returned by EventSubscription::recv and LifecycleSubscription::recv.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Closed

The producer is gone — the session has shut down or the client has stopped. No further events will be delivered.

Lagged(Lagged)

The subscriber fell behind. See Lagged.
