Struct grpcio::ServerStreamingSink

#[must_use = "if unused the sink may immediately cancel the RPC"]
pub struct ServerStreamingSink<T> { /* fields omitted */ }

A sink for server streaming call.

To close the sink properly, you should call close or fail before dropping.

Methods

impl<T> ServerStreamingSink<T>

pub fn set_status(&mut self, status: RpcStatus)

pub fn fail(self, status: RpcStatus) -> ServerStreamingSinkFailure

Trait Implementations

impl<T> Drop for ServerStreamingSink<T>

fn drop(&mut self)

The corresponding RPC will be canceled if the sink did not call close or fail before dropping.

impl<T> Sink for ServerStreamingSink<T>

type SinkItem = (T, WriteFlags)

The type of value that the sink accepts.

type SinkError = Error

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

fn start_send(
    &mut self,
    item: Self::SinkItem
) -> StartSend<Self::SinkItem, Error>

Begin the process of sending a value to the sink.

fn poll_complete(&mut self) -> Poll<(), Error>

Flush all output from this sink, if necessary.

fn close(&mut self) -> Poll<(), Error>

A method to indicate that no more values will ever be pushed into this sink.

fn wait(self) -> Wait<Self>

Creates a new object which will produce a synchronous sink.

fn with<U, F, Fut>(self, f: F) -> With<Self, U, F, Fut> where
    F: FnMut(U) -> Fut,
    Fut: IntoFuture<Item = Self::SinkItem>,
    <Fut as IntoFuture>::Error: From<Self::SinkError>, 

Composes a function in front of the sink.

fn with_flat_map<U, F, St>(self, f: F) -> WithFlatMap<Self, U, F, St> where
    F: FnMut(U) -> St,
    St: Stream<Item = Self::SinkItem, Error = Self::SinkError>, 

Composes a function in front of the sink.

fn sink_map_err<F, E>(self, f: F) -> SinkMapErr<Self, F> where
    F: FnOnce(Self::SinkError) -> E, 

Transforms the error returned by the sink.

fn sink_from_err<E>(self) -> SinkFromErr<Self, E> where
    E: From<Self::SinkError>, 

Map this sink's error to any error implementing From for this sink's Error, returning a new sink.

fn buffer(self, amt: usize) -> Buffer<Self>

Adds a fixed-size buffer to the current sink.

fn fanout<S>(self, other: S) -> Fanout<Self, S> where
    S: Sink<SinkItem = Self::SinkItem, SinkError = Self::SinkError>,
    Self::SinkItem: Clone, 

Fanout items to multiple sinks.

fn flush(self) -> Flush<Self>

A future that completes when the sink has finished processing all pending requests.

fn send(self, item: Self::SinkItem) -> Send<Self>

A future that completes after the given item has been fully processed into the sink, including flushing.

fn send_all<S>(self, stream: S) -> SendAll<Self, S> where
    S: Stream<Item = Self::SinkItem>,
    Self::SinkError: From<<S as Stream>::Error>, 

A future that completes after the given stream has been fully processed into the sink, including flushing.
