Struct TestCommunicationBackend 

pub struct TestCommunicationBackend {
    outgoing_tx: Sender<OutgoingMessage>,
    outgoing_rx: Receiver<OutgoingMessage>,
    outgoing: Arc<RwLock<Vec<OutgoingMessage>>>,
    incoming_tx: Sender<IncomingMessage>,
    incoming_rx: Receiver<IncomingMessage>,
}

Fields

outgoing_tx: Sender<OutgoingMessage>

outgoing_rx: Receiver<OutgoingMessage>

outgoing: Arc<RwLock<Vec<OutgoingMessage>>>

incoming_tx: Sender<IncomingMessage>

incoming_rx: Receiver<IncomingMessage>

Implementations

impl TestCommunicationBackend

pub fn new() -> Self

Create a new test communication backend.

pub fn push_incoming(&self, message: IncomingMessage)

Inject a message as if it were received from a remote endpoint.

pub async fn outgoing(&self) -> Vec<OutgoingMessage>

Get a copy of all the outgoing messages that have been sent.

pub async fn drain_outgoing(&self) -> Vec<OutgoingMessage>

Trait Implementations

impl Clone for TestCommunicationBackend

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CommunicationBackend for TestCommunicationBackend

type SendError = ()

Error returned by send, classified via IpcErrorKind.

type Receiver = TestCommunicationBackendReceiver

Receiver type returned by subscribe.

async fn send(&self, message: OutgoingMessage) -> Result<(), Self::SendError>
