Struct Sink

pub struct Sink<T, E = Error> { /* private fields */ }

Subscriber sink.

Implementations

impl<T: Serialize, E: Serialize> Sink<T, E>

pub fn notify(&self, val: Result<T, E>) -> SinkResult

Sends a notification to the subscriber.

Trait Implementations

impl<T: Clone, E: Clone> Clone for Sink<T, E>

fn clone(&self) -> Sink<T, E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug, E: Debug> Debug for Sink<T, E>

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

Formats the value using the given formatter.

impl<T: Serialize + Unpin, E: Serialize + Unpin> Sink<Result<T, E>> for Sink<T, E>

type Error = SendError

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send( self: Pin<&mut Self>, item: Result<T, E>, ) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.
