Struct ConnectionInterface 

pub struct ConnectionInterface { /* private fields */ }

The reciprocal of ConnectionHandle.

Implementations

impl ConnectionInterface

pub fn send_to_frontend( &self, item: PubSubItem, ) -> Result<(), SendError<PubSubItem>>

Send a pubsub item to the frontend.

pub async fn recv_from_frontend(&mut self) -> Option<Box<RawValue>>

Receive a request from the frontend. Ensures that if the frontend has dropped or issued a shutdown instruction, the backend sees no more requests.

pub fn close_with_error(self)

Close the interface, signaling a generic backend-gone error to the frontend.

The pubsub service will attempt to reconnect using the configured retry policy. Use Self::close_with_transport_error to opt out of the reconnect loop on deterministic, non-retryable failures.

pub fn close_with_transport_error(self, err: TransportError)

Close the interface, signaling a specific transport error to the frontend.

Use TransportErrorKind::non_retryable_str / TransportErrorKind::non_retryable to construct an error that short-circuits the pubsub service’s reconnect loop. Any other error kind triggers the normal reconnect-with-retries path.

Trait Implementations

impl Debug for ConnectionInterface

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
