Trait Implementations

impl<T, E> Stream for Body<T, E>

type Item = T

The type of item this stream will yield on success.

type Error = E

The type of error this stream may generate.

fn poll(&mut self) -> Poll<Option<T>, E>

Attempt to pull out the next value of this stream, returning None if the stream is finished.

fn wait(self) -> Wait<Self>

Creates an iterator which blocks the current thread until each item of this stream is resolved.

fn map<U, F>(self, f: F) -> Map<Self, F> where F: FnMut(Self::Item) -> U

Converts a stream of type T to a stream of type U.

fn map_err<U, F>(self, f: F) -> MapErr<Self, F> where F: FnMut(Self::Error) -> U

Converts a stream of error type T to a stream of error type U.

fn filter<F>(self, f: F) -> Filter<Self, F> where F: FnMut(&Self::Item) -> bool

Filters the values produced by this stream according to the provided predicate.

fn filter_map<F, B>(self, f: F) -> FilterMap<Self, F> where F: FnMut(Self::Item) -> Option<B>

Filters the values produced by this stream while simultaneously mapping them to a different type.

fn then<F, U>(self, f: F) -> Then<Self, F, U> where F: FnMut(Result<Self::Item, Self::Error>) -> U, U: IntoFuture

Chain on a computation for when a value is ready, passing the resulting item to the provided closure f.

fn and_then<F, U>(self, f: F) -> AndThen<Self, F, U> where F: FnMut(Self::Item) -> U, U: IntoFuture<Error=Self::Error>

Chain on a computation for when a value is ready, passing the successful results to the provided closure f.

fn or_else<F, U>(self, f: F) -> OrElse<Self, F, U> where F: FnMut(Self::Error) -> U, U: IntoFuture<Item=Self::Item>

Chain on a computation for when an error happens, passing the erroneous result to the provided closure f.

fn collect(self) -> Collect<Self>

Collect all of the values of this stream into a vector, returning a future representing the result of that computation.

fn fold<F, T, Fut>(self, init: T, f: F) -> Fold<Self, F, Fut, T> where F: FnMut(T, Self::Item) -> Fut, Fut: IntoFuture<Item=T>, Self::Error: From<Fut::Error>

Flattens a stream of streams into just one continuous stream.

fn skip_while<P, R>(self, pred: P) -> SkipWhile<Self, P, R> where P: FnMut(&Self::Item) -> R, R: IntoFuture<Item=bool, Error=Self::Error>

Skip elements on this stream while the predicate provided resolves to true.

fn for_each<F>(self, f: F) -> ForEach<Self, F> where F: FnMut(Self::Item) -> Result<(), Self::Error>

Runs this stream to completion, executing the provided closure for each element on the stream.

fn take(self, amt: u64) -> Take<Self>

Creates a new stream of at most amt items of the underlying stream.

fn skip(self, amt: u64) -> Skip<Self>

Creates a new stream which skips amt items of the underlying stream.

fn fuse(self) -> Fuse<Self>

Fuse a stream such that poll will never again be called once it has finished.

fn catch_unwind(self) -> CatchUnwind<Self> where Self: UnwindSafe

Catches unwinding panics while polling the stream.

fn buffered(self, amt: usize) -> Buffered<Self> where Self::Item: IntoFuture, Self::Item::Error == Self::Error

fn forward<S>(self, sink: S) -> Forward<Self, S> where S: Sink<SinkItem=Self::Item>, Self::Error: From<S::SinkError>

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

fn split(self) -> (SplitSink<Self>, SplitStream<Self>) where Self: Sink

Splits this Stream + Sink object into separate Stream and Sink objects, which can be useful when you want to split ownership between tasks, or allow direct interaction between the two objects (e.g. via Sink::send_all).
