pub struct CompatSink<T, Item> { /* private fields */ }

Available on crate feature compat only.

Implementations

impl<T, Item> CompatSink<T, Item>

pub fn new(inner: T) -> CompatSink<T, Item>

Creates a new CompatSink.

pub fn get_ref(&self) -> &T

Get a reference to 0.3 Sink contained within.

pub fn get_mut(&mut self) -> &mut T

Get a mutable reference to 0.3 Sink contained within.

pub fn into_inner(self) -> T

Returns the inner item.

Trait Implementations

impl<T, Item> Debug for CompatSink<T, Item>where T: Debug, Item: Debug,

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

Formats the value using the given formatter.

impl<T, Item> Sink for CompatSink<T, Item>where T: Sink<Item> + Unpin,

type SinkItem = Item

The type of value that the sink accepts.

type SinkError = <T as Sink<Item>>::Error

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

fn start_send( &mut self, item: <CompatSink<T, Item> as Sink>::SinkItem ) -> Result<AsyncSink<<CompatSink<T, Item> as Sink>::SinkItem>, <CompatSink<T, Item> as Sink>::SinkError>

Begin the process of sending a value to the sink.

fn poll_complete( &mut self ) -> Result<Async<()>, <CompatSink<T, Item> as Sink>::SinkError>

Flush all output from this sink, if necessary.

fn close( &mut self ) -> Result<Async<()>, <CompatSink<T, Item> as Sink>::SinkError>

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

fn wait(self) -> Wait<Self>where Self: Sized,

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>, Self: Sized,

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>, Self: Sized,

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, Self: Sized,

Transforms the error returned by the sink.

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

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>where Self: Sized,

Adds a fixed-size buffer to the current sink.

fn flush(self) -> Flush<Self>where Self: Sized,

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

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

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>, Self: Sized,

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