Struct futures_util::stream::Zip

#[must_use = "streams do nothing unless polled"]
pub struct Zip<St1: Stream, St2: Stream> { /* fields omitted */ }

An adapter for merging the output of two streams.

The merged stream produces items from one or both of the underlying streams as they become available. Errors, however, are not merged: you get at most one error at a time.

Trait Implementations

impl<St1: Debug + Stream, St2: Debug + Stream> Debug for Zip<St1, St2> where     St1::Item: Debug,     St2::Item: Debug,

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

Formats the value using the given formatter.

impl<St1: Stream + Unpin, St2: Stream + Unpin> Unpin for Zip<St1, St2>

impl<St1, St2> Stream for Zip<St1, St2> where     St1: Stream,     St2: Stream,

type Item = (St1::Item, St2::Item)

Values yielded by the stream.

fn poll_next(self: PinMut<Self>, cx: &mut Context) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.
