Enum ErasedSinkTrySendError

pub enum ErasedSinkTrySendError {
    Full,
    Disconnected,
    Other(Arc<dyn Error + Send + Sync + 'static>),
}

Type-erased error for SinkTrySend::try_send

Provided for situations where providing a concrete error type is awkward.

futures::channel::mpsc::Sender wants this because when its try_send method fails, it is not possible to extract both the sent item, and the error!

tor_memquota::mq_queue::Sender wants this because the types of the error return from its try_sendwould otherwise be tainted by complex generics, including its privateEntry` type.

Variants

Full

The stream was full.

No arrangements will have been made for a wakeup when space becomes available.

Corresponds to SinkTrySendError::is_full

Disconnected

The stream has disconnected

Corresponds to SinkTrySendError::is_disconnected

Other(Arc<dyn Error + Send + Sync + 'static>)

Something else went wrong
