Struct sink_splitter::Splitter

pub struct Splitter<K: Eq + Hash, S> { /* fields omitted */ }

This is the input Sink that routes each item to one of many output sinks. This sink takes as input (K, V) pairs where K is the key that determines which output sink to route to and V is the value that is sent to the output sink.

Methods

impl<K, V, E, S> Splitter<K, S> where
    K: Clone + Eq + Hash,
    S: Sink<SinkItem = V, SinkError = E>,
    E: Debug, 

fn into_sinks(self) -> HashMap<K, S>

Consume this Splitter and return its map of output sinks. Note that this function does not close any of the sinks.

Trait Implementations

impl<K: Debug + Eq + Hash, S: Debug> Debug for Splitter<K, S>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<K, V, E, S> Sink for Splitter<K, S> where
    K: Clone + Eq + Hash,
    S: Sink<SinkItem = V, SinkError = E>,
    E: Debug, 

type SinkItem = (K, V)

The type of value that the sink accepts.

type SinkError = Error<K, V, E>

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

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

Begin the process of sending a value to the sink.

fn poll_complete(&mut self) -> Poll<(), Self::SinkError>

Flush all output from this sink, if necessary.

fn close(&mut self) -> Poll<(), Self::SinkError>

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 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.
